Given that every business needs a bed a place in the geography of this place, defined geographical space. This geographical space supplier of tourist activities. Many factors affect the tourism industry, one of the most important climates. Along with geographic location, topography, landscape, flora and fauna, water and air as one of the most important local resource base plays a role in the development of tourism industry. Gilan province is one of the countries northern even with Mesa 14711 square kilometers. The province has two different morphology of the southern part of the province of North Alborz heights shown and the foothills and plains in coastal areas. The province because of the special circumstances of the geographical, exquisite natural scenery and abundant water resources in the row is one of the most tourist areas of the country. In this study, with the presentation of applied research, analytical and application software, Excel, Google Earth, ArcGIS10 to check the status of existing and potential climate in Gilan province was one of the country's Northern provinces. Which has convenient facilities in the field of tourism is also significant to analyze the specific situation of the province and also to discuss tourism and its development will conform to discuss climate. The result of climatic classification methods Domarten temperature and precipitation maps also will be show that there are good conditions for tourism development in the province and Finally, using the climate index TCI zoning province, and the results were presented in the field of tourism.

One of the UN Millennium Development Goals is women's participation in urban management. This article develops a theoretical framework for analyzing the relationship between community-based planning and women participation in cities. In this regard, collective action, social capital, and neighborhood as location for community planning are used. The framework identifies a series of variables that are theorized to affect a community's capacity to women participation. Method of study is analytical descriptive. The statistical population is women over 18 years old in Nematabad neighborhood. 29 questionnaires are distributed randomly. According to the findings it is recommended that, the strategy for development of community-based planning can be very effective in urban planning system in Iran as this strategy for host communities could bring about social welfare, justice, and socio-economic suitability. Also Social Network, marriage, education level, employment are the most important elements that affect women's participation in the development of community-driven development programs.

The destruction of the rivers and, consequently, the need to reconstruct them, is one of the known important problems in throughout the world. However, suitable methods for assessing the morphological changes (morphology) associated with this action, as well as the cognition of the effect of the morphological factors in order to intervention in the process of river reconstruction, are still being explored. The JAJROOD and LATYAN-dam areas in the north east of Tehran due to the pleasant weather have always been and are in Eco tourists and nature interested people noteworthy. For this reason, during the recent decades and because of human manipulations, the JAJROOD River basin and its margins have been heavily affected. Hence the study of hydro morphological changes in this river is strongly needed. The object of this research is to evaluate the hydro morphological conditions of one part of JAJROOD River using the MQI method. Accordingly, Landsat 8 satellite images of 2018 and Landsat 4 in 1976 were prepared and were take placed several field observations. The results of the research show that all areas of the region are in poor and very weak conditions regarded to the MQI method. These problems are caused by the cutting of trees in order to create human structures, harvesting sand, creating numerous promenades along the river's estuaries and changing the river pattern.

The horizontal and urban growth of the past few generations, due to the dominance of the centralized planning system in the country, has led, in accordance with the principle of village-to-city interconversions, that many villages located around cities have undergone numerous changes and changes in the indicator status Of development. These changes, in addition to having positive aspects in most cases, have had a negative impact on the sustainable development of rural areas located in the vicinity of these cities. In the current applied research, a quantitative and qualitative approach with a spatial and descriptive-analytic approach has been carried out. The main objective of this research is to identify the consequences of the Marivan Creep phenomenon on the changes in the development status of the surrounding villages, Over the last few decades, physical development has been speeding up. Data gathering in the theoretical part of the documentary and in the field was conducted by a survey method based on an interview with the local people and the locals to identify the outcomes, and then the classical distribution of the questionnaire among the studied villages and simple random among 203 households supervised by The Cochran formula was determined by volume, 30 from local development experts and observers of the status quo, in order to generalize the findings from the interviews. The results of analyzing the data with the fundamental theory of the technique in the qualitative section and the single-sample t-test in the quantitative section showed that the urban creep phenomenon, in addition to limited positive consequences in improving the physical condition, caused social deficiencies, failure Economic problems, inadequate visual quality, natural environment degradation and institutional management failures in the development of villages studied.

In recent years with the development of cities coatings of the Earth's has changed surface. These changes have caused some urban areas to have a few degrees higher than the surrounding temperature. This phenomenon is known as thermal islands. Mashhad is one of the major metropolises in Iran with the problem of thermal islands. Various parameters affect the formation of thermal islands in this city that should be considered. In this study TM, ETM+ and OLI images were used to obtain surface temperature over the period 1987-2016. The study of temporal variations in surface temperature showed that in the studied period, thermal islands were transferred from outside the city to the city. The model for describing the temperature of the surface of the earth has changed and has diminished from the temperature of the city's moderate and cool temperatures, and in contrast, the amount of high temperatures (thermal islands) has increased significantly. The TOPSIS method was also used to obtain the thermal forming factors. 13 natural and human factors affecting the formation of thermal islands were identified. Each expert opinion factor was used to determine the degree of importance. According to experts, the distance from the sanctuary with a weight of %234 and traffic of %155 is the most important and the height with a weight of %022 is least important in the formation of thermal islands. The final results obtained from this model showed that the factors affecting the formation of thermal islands are well recognized and the temperature decreases with these factors.

Today, in view of the growing population and population density in urban areas, especially in densely populated and susceptible cities, the need for an inclusive and comprehensive approach to natural disasters and disasters caused by their occurrence has become more evident. Focusing more than the size of the population in specific urban areas, lack of preventive planning and lack of readiness to deal with accidents such as earthquakes, is a very serious and important threat to citizens and the survival of the city. The capital city of Karaj, as one of the major cities in Iran, has a high risk of earthquakes due to the presence of several active faults inside and outside it. Accordingly, investigations of the seismic vulnerability of this city are one of the necessities of Karaj city management. Regarding this, the metropolis of karaj was selected as the study area. The method of research and analysis of information collected based on database-based methods using the ELECTRE FUZZY model and Criteria for building materials, number of floors, quality of buildings, population density, building density, area of parts, width of passageways, geology, distance from faults, distance from medical centers, distance from public space, distance from urban facilities and travel compatibility for research purposes Were used. The results indicate that 6, 8, 1, and 7 areas of Karaj municipality are vulnerable to earthquake, so that more than 70 percent of Karaj city is vulnerable to earthquake vulnerability on low and low floors and Only about 20% of the city of Karaj due to its proximity to the fault and the high density of population, construction and. . . is in high and high risk areas. According to the principles of urban planning, the regulations of 2800 can cover earthquake damage in these areas.

In this research, the development of cross-border cooperation (CBC) to study the factors and stimuli affecting the stability of the: : : : union: : : : in the border regions were discussed. The aim of the present study, functional and combination method (qualitative and quantitative) is. The data-gathering tool was a questionnaire and interview. The statistical community included various experts in the fields of political science, geography, economics, sociology, law enforcement experts, governorate and governorate in Sistan and Baluchestan province. Using a targeted sampling, 70 experts were selected. For analysis of data, descriptive tests and binary logistic regression model (LM-Newton-Marcard-Raphson method) were used. The results showed that in the area of planning for unity in Sistan and Baluchestan except for the determination of the right of the Hirmand River in the Sistan region, which was concluded with the country over a period of time, the plan was not approved or implemented, and among the five factors Economic, social, cultural-religious, institutional-structural and political security, three economic factors (0. 478), political-security (0. 473) and cultural-religious (0. 363) have the most effect on the stability of unity of border regions in Studied area. The results of this study can be used to develop border cooperation cooperation and coherence stability in different border regions of Iran.

Land use maps are considered as the most important sources of information in natural resource management. The purpose of this research is to review, model, and predict landslide changes in the 30-year period by LCM model in Shiraz. In this research, TM Landsat 4, 5 and OLI Landsat 8 images were used for 1985, 2000 and 2015 respectively, as well as topographic maps and area coverage. Subsequent validation and detection of changes were made using the prediction model of variation The use of LCM markov and the model of user change approach. The images were classified into four classes of Bayer, garden, urban lands, and arable land for each of the three periods. According to the results, aquaculture is the most dynamic user in the area, which has led to an upward trend during 1985-2015, so that the amount (4337 ha, 12. 7%) has been added to this area. The Bayer user change trend was also a downward trend during 1985 to 2015, reducing the 99. 1995 hectares of this class. The results of the change in the 1985 changes with a kappa coefficient of 0. 88, in the 2000 period with a CAAP of 0. 77, and in the period 2015 with a Kappa coefficient of 0. 92. The results of the change detection in 2030 are such that if the current trend continues in the region, 20. 33% will be added to the crop category, so that in 2030, agricultural cropping will be 95. 60% of the area of the area Gets In the Bayer and Garden uses 21. 22% and 0. 21% of the total area of each user has been reduced and has been added to the urban area. The prediction map derived from the Markov chain model is very important for providing a general view for better management of natural resources.

The purpose of this study is to determine the evapotranspiration in Fars province that in many studies such as hydrological balance of water, irrigation systems design and management, simulation of product volume and management of water resources is very important. To do this, first, required data such as daily temperature, humidity, precipitation, wind speed, solar radiation pressures, solar radiation, etc. was collected. We used 12 stations with the same statistical interval, for the period 1995-2015. In order to estimate the evapotranspiration of the reference plant in different growth stages, Torent White, Penman-Monteith and Hargreaves-Samani methods were used. Results showed that with decreasing latitude, the evapotranspiration rate increased, and the highest rate of evapotranspiration occurs in the south, southeast and the center of the study area. The correlation coefficient R2 between height and White Penman, Monteith and Hargreaves Samani, are 0. 9135, 0. 53223 and 0. 5286 respectively.

the occurrence of landslides in the direction of rivers, especially in the mountainous regions of Zagros range are processes that block rivers and form lake barriers. Della Landslide is an example of such landslide that occurred in the course of Shimbar River drainage and eventually created Lake Shimbar. geoarchaeological field studies performed on this slide using topographic maps, geological, digital model of the area, satellite images and Arc GIS software on the landslide and basin lake Shimbar resulted in the identification of the causes of landslides and changes in three stages of the lake. This study eventually rebuilds Paleogeomorphology of landslide area and the lake's dam Shimbar. The results showed that the main cause of the occurrence of landslides were tectonic processes in the region and based on archaeological evidence and the archaeological excavation of the canal, the landslides occurred before 2000 years ago. The formation and changes in the scope and depth of the lake Shimbar in 3 stages blocked the migration routes in area for a long time.

The extention of Snow cover and its spatial and temporal changes considered as a basic parameter in climatic and hydrologic studies. Data from satellite images due to the low cost and the large extention of cover are, effectively help the identifying of the snowy basins. Since the satellites are able to imaging a surface at different times, this will allow snow survey studies to investigate the spatial and temporal distribution of snow. In this research, Snow line changes and the surface temperature line in Alborz Mountains using NOAA-AVHRR satellite images since 2006 from 2015 was studied. The results showed that at the study period, maximum area of snow have been observed in April 2015, with the amount of 12051 square kilometers and the minimum area snow have been observed in June 2008, with the amount of 33 square kilometers. The average of the lowest elevation of snow covered areas, have been observed in April 2007, with the amount of 2662 meters and its highest value have been observed in June 2008 with the amount of 3820 meters. Also the most of the snow line change occurred between the years 2007 to 2008. Moreover, in almost of 15 years, the isoterm of zero degrees Celsius, matches with the snow line and its elevation has changed as the snow area is changed.

Quite a lot of people are employed in gas production and refining industry in IRAN. In case of weakness or lack of having an effective management, the associated companies will impose heavy damage to the country. In this regard, to achieve consistency and safety in IRAN, ascendancy of management in these companies is one of the main and effective attempts.

Subsequently, a questionnaire using Delphi technique is prepared and conducted over the statistical population. The obtained data was analyzed with SPSS and AMOS software, and the results showed that among the other factors, human resource has more considerable effect on crisis management.

The purpose of this research is to study the comfort conditions and determine the best measures for design and architecture compatible with the climate in Yazd. In this regard, the climatic data of Yazd city has been used in EPW format during the period (1981-2017). The results of the study of temperature and relative humidity also showed that temperatures of more than 38 ° C are visible in June and July. This suggests the need for a shadow in the architecture of the climate. In July, the discomfort conditions prevail over the entire day. From June to October (midday to midnight), midnight hours due to low humidity (38%) and high temperatures, conditions of discomfort and drought are very visible. The highest humidity is in the cold months of the year. In the wind hours of February to May (February to April), there is a discomfort. Also, according to the overall radiation pattern at different hours of the day, it was also shown that 25% of the daylight hours is very high and non-comfort, and 8% are in comfort conditions, which is more related to the cold weather of the year and the early hours And the end of the day. In general, due to the climate of Yazd city and the results of analysis, 20 strategies for architectural design have been used.

With the increasing population in cities, particularly big cities, demand for public goods and services increased too. But, due to certain political-economic structure of the country, often the rates of supplies growth have been less than the demands’ . The high-demand applications such as educational, for many reasons including, Lack of cities’ coordination executive bodies, financial problems and lack of education sector officials with scientific procedures for locating schools, faced with many problems to meet the needs of the students. In large urban areas like Tehran, for various reasons such as high population density and scarcity of land, these problems intensified. Fast, timely and appropriate accessibility to these training centers is very important and necessary in every community, especially in urban areas. And the equitable distribution of these centers in the city led to the establishment of spatial equity and social justice, which is an urban sustainable development objectives. The aim of this research is to evaluate the locating of training centers in primary schools in the district in order to achieve spatial justice. The type of research is practical, based on the purpose of thstudy, and the research method is descriptive-analytic. The data collection method is also documentary-survey. In order to weigh the criteria, experts have been used in the ANP model, and by Using the capabilities and features of geographical information system including: combining maps, raster calculator, network analysis and etc. has been done. Finally, after the implementation of VIKOR sample, the priority areas were identified for building elementary schools. The final output analysis obtained by this method in addition to determining of the compatibility or incompatibility of primary schools in the city will located the optimal sites for building new elementary schools.

Industrial revolution and its resulting changes have led to urban horizontal growing. Environmental pollution, more energy consumption, development without planning, Increased spending on infrastructure, particularly in the area of urban construction are the consequences of the urban horizontal growing. To remedy the crisis, efforts have been made to recognize patterns of urban development and the realization of sustainable urban form. Meanwhile, the compact city strategy was presented to solve the proposed problems. Compact city is an urban strategy to tackle the problem of sporadic and uncontrolled physical growth of cities. This study aimed to identify the obstacles to the realization of compact city strategy in the central part of Sari. The research method is qualitative on the basis of a theoretical approach. Data was collected in two ways of documentation and semi-structured interviews. The sample included people involved in urban development projects. Purposeful sampling was done using the snowball technique and finally 10 specialists in the research area were selected as the study sample. Results suggest that the presence of monuments, low interest of investors for construction, and inefficient transport system were among the obstacles of the realization of compact city strategy in the research area.

Today, the huge economic damage of natural hazards, especially of the micro-organisms, to human societies has led the concept of economic sustainability to mitigate the effects of crises to become an important area in crisis management. The purpose of this study was to investigate the role of environmental hazards (effluents) on Ahwaz economy. This research can be considered as a type of applied-development research, and is a descriptive-analytical study in a correlation manner. The population of the study consisted of all residents of Ahwaz, in 1395, there were no more than 1302000 people. The sample size was 384, based on the Cochran formula, and randomly available. To investigate the data, the structural equation path analysis was used in Amos18 software. The results indicated that the microprocesses had an effect on the economy of Ahwaz with a coefficient of 0. 31 and a significant level of 0. 002. Also, the effect of fiery gradients was 0. 73, and the significance level of 0. 000 on the tax, the microguns, with the coefficient of influence 0. 45 and the significance of 0. 000 per facility, the effects of the micrographs with the coefficient of 0. 55, and the significance of 0. 000 on the housing, With a coefficient of influence of 0. 17 and a significant amount of 0. 008 on transportation. Accordingly, microblogging has the most impact on finance with a coefficient of 0. 73, and transportation with a coefficient of influence of 0. 17 has had the least effect.

Vulnerability can be considered as an inherent defect in particular dimensions of the urban environment that is susceptible to damage due to its biological and physical characteristics or design features. Therefore, the present study aimed to investigate Ahwaz city structures and fine-tune its vulnerability from a passive defense perspective and to move it towards the future prospects of a safe city. This research is applied in terms of purpose and in terms of descriptive-analytical methodology based on the spatial-model studies approach. The data of this study include 11 educational, fire, administrative, police, power lines, terminals, urban facilities, business centers, roads, urban industries, gas transmission centers and health centers. GIS software was used to analyze the research data. Therefore, distance maps were designed and standardized for measuring the neighboring pattern after identifying the effective layers in the vulnerability and using the Distance tool. The FUZZY OVERLAY tool in ArcGIS software was used for spatial distribution and micro-zoning of Ahwaz vulnerability. The results show that in the section of vulnerability zoning, 29. 73% of the city area is completely vulnerable, 29% vulnerable, 21. 18% moderate, 13. 22% low and 6. 85% of the total city area in the state of vulnerability, respectively. There is very little reception.

A city is a vibrant, dynamic, and evolving phenomenon that grows and spreads over time and space, and is exhausted and degraded. It also faces crises such as natural hazards and artifacts, resulting from human relationships and physical elements, on the one hand, and social, economic, cultural, geographical, political, and historical conditions on the other. The deteriorated urban fabric, which has physical, functional and operational deterioration, are resistant to the above-mentioned crises and has low vulnerability. Therefore, the need of intervening in these fabrics is crucial for balancing, coordinating the foundations of social life, and improving the urban structure. In this regard, in this research, priority is given to the dimension of resilient deteriorated urban fabric based on a disaster resilience of place model which is one of the models of urban resilience measurement. This research is a descriptive-analytical according to method and is developmental-applied research in terms of the purpose. Also, Expert Choice software and AHP model are used to analyze the collected data by using a questionnaire. The results of the research indicate that, in three macro areas of Karaj, Hesarak and Mehrshahr, the physical-environmental resilience dimension has the highest weight and organizational-institutional resilience has the least weight. Overall, regarding prioritization of resilience dimensions, criteria and indicators, an increasing per capita of vital use in study areas, changing the economic structure of residents, as well as increasing the skill and coherence of citizens to deal with hazards and crises are important.

Cities are dramatically turning into complex social, economic, and environmental systems. Each urban system is vulnerable when it can not adapt to its changing conditions and critical situations. Therefore, in recent decades, natural disaster response approaches have introduced a new concept of urban resilience to prepare for disaster as much as possible. Is. Despite the recent attention and the abundant use of the concept of resilience in different areas of theoretical and practical limitations of this concept, this study aims to explain the causal pattern of resilience of cities. The present research is based on the descriptive-causal methodology. The statistical sample of the study was compiled by 35 experts and specialists in urban planning. Fuzzy Dumbled Fan was used to achieve the research goal. The findings of this study showed that based on the values of D-R, among the four metrics of urban resilience, the physical criterion with the value (0. 943) was the most effective measure of resilience in the city. Also, based on the D + R values, the physical criterion with the value of (896/2) was identified as the most important resiliency criterion in the city.
