Many indices have been suggested by scholars for studying biometeorology and bioclimatology which are used in the tourism climatology. Among them, the thermo-physiological indices which are based on the human energy balance model are more reliable. In this study to find the most appropriate time for tourism on Persian Gulf and Oman sea shores and to determine the time and place differences of comfort zone in the various seasons of the year, the daily data for 19 years from 1987-2005 for 6 main stations have been selected and analyzed with PET and PMV indices. The result of this study which has been done by RayMan model show that on the Persian gulf shores the thermal comfort days scattered in the hole years except for February which the throughout of the region experiences the cold tensions. On the Oman sea shores there is thermal comfort too from the mid of January to the mid of April. We found by comparing the comfort days of the stations on the Persian Gulf shore and the stations on the Oman sea shore on the basis of the selective factors, that the climatic comfort of Oman sea shores is more than that of Persian Gulf and a high percentage of non-comfort condition of Persian Gulf and Oman sea shores is because of the sultry of the these region.

Dolines are the major landforms in Takt-e-Soleiman region which have been created in different forms and sizes. Dolines have not been distributed equally on the surface of the region. Variables like: area, perimeter, depth, and height from sea level are different and caused to special landscape in this karstic region. This study tries to consider all four variables and indicates the effect of change of each variable on another. Measurements of dimensions have been done by land surveying and by field studies for indicating quantitative characteristics. After statistics analysis following results are indicated: Although the biggest doline is located on the highest part of the region, there isn’t direct relationship between height from sea level and doline area. The perimeter of dolines have a significant relationship with area of dolines but this relationship with depth and height is very poor. In study of dolines of this region indicated that with the rise of the height, depth is increased too.The height is an important variable which as independent variable has effect on the other variables. Depth and perimeter are influenced by height. Height factor can have notable influence on area but tectonic caused to restricting area of dolines and lack of relationship with height.

The cultivation and harvesting of oil seeds is of prime importance in the world today. As Canola is a type of economical oil seed, attempts have been underway to enrich the layers underlying its cultivation. However, it should be noted that owing to the effects of various factors on the growth and performance of autumn Canola, procedures to assess the suitability of sites for the cultivation of Canola require access to comprehensive descriptive information regarding the sites. GIS technology makes it possible to profit from such information and facilitates the spatial analysis of information using relevant models. Therefore, in the present study, considering the ecological needs of autumn Canola, Multi Criteria Decision Making techniques based on Analytical Hierarchy Process was used and modeling and spatial analysis of information was performed with the help of ARC/GIS 9.3 software. Finally, zones favorable to the cultivation of autumn Canola in the province of Ardabil were evaluated and demarcated. The results of the study show that regarding Canola cultivation, areas that have severe restrictions, relatively high restrictions, moderate restrictions, few restrictions and no restrictions make up 43.23%, 31.66%, 16.70%, 18.36% and 9.85% respectively, of the total provincial area.

Political geography and geopolitics of Tehran metropolis is full of historical and political experiences of Iranian nation. This city has acted as the heart of Iran and the main base of the country in all political, economic, cultural, and social dimensions and even military and security affairs for more than two centuries.Perhaps when Tehran was selected as Iran’s capital city, one might not have thought that this city, at least for a long period even after the change of state structure and regime of Iran, would remain as Iran’s capital city. Accordingly, review of the political history of this city during its political life, shows that during the last two centuries, vital key of survival of Iran lies in the political centrality of this city. However, in accordance with the realities of the Iranian political geography, it is not acceptable that Tehran’s politics would be stable forever. In general, the main purpose of this paper is the study and analysis of Tehran’s role as a power center in Iran’s political geography structure and political organization of its space.

Some of the criticism of modern cities is about the boring urban life which is the result of inappropriate urban spaces.Besides the statistics show that the urban areas are growing. Unfortunately, this physical development is being done regardless and without paying attention to the importance of cultural and recreational needs of the urban dwellers. The insufficient recreational facilities are among the main factors which are considered as an important obstacle for public participation and lack of social communication. Making recreational land use for all the citizens has become the first priority in modern approaches in urban planning. Developing these spaces has been considered as the basic necessity in promoting the quality of urban life and urban spaces. The main goal of this article is to find the relation between the amount of recreational land use and the promotion of urban culture and public participation. In this survey some indicators and mathematical parameters have been used. Besides, a questionnaire, with closed end questions based on Likert scale has been designed and its validity and reliability had been tested. Probability sampling was done and about three hundred residents in three main regions were interviewed. The results of these interviews were analyzed by SPSS software.Although many efforts have been recently done by urban managers in Tehran, the results of this survey show that people are not completely satisfied with the recreational land use. Results also show that there is no statistical relation between developing recreational land use and promoting urban culture.

In metropolitans, site selection of the services and using elements of new techniques like GIS is a main issue in practical aims of the urban planning. Using GIS and AHP models, the present paper is an attempt to assess the current condition and select the best site to place public libraries in Ahvaz. The SWOT method was also used to analyze the effective criteria in site selection for libraries. Finally, considering the centrality and consistency criteria, new sites are proposed. Presently, the libraries are not located in good places. Moreover, Ahvaz requires eleven extra public Libraries.

As meteorological data is considered an essential and basic data for different studies, hence, performance of various research projects as well as designing different development programs primarily depend on them. Based on these necessities and GIS applicability, a project related to GIS applications in climatological data has been designed and executed for the East Azerbaijan Agricultural and Natural Resource Researches Center. This project was mainly based on ArcGIS ILWIS and Access software. Firstly, all climatological recorded data were collected from different meteorological stations. Some statistical methods were applied for quality controlling of gathered data. Then, a Geo-database was established based on verified data into GIS environments. Like as other GIS databases, this geo-database consists spatially and attributes characteristics of meteorological data which were monthly organized on the basis daily observed data. This project can support different research programs in form of spatial analysis fulfillment. Obtained results can be exhibited in form of thematic maps, tabular or text files. The present work aims to present theoretical aspects of GIS applications into climatological studies. Demonstration of further utilizing of GIS applicability is considered too.

During three recent decades, because of augmentation of the damaging consequences followed by desolation of gardens, and green areas inside cities, as well as countryside, organization of urban green space activities seems to be inevitable. According to special part played by local parks in order to regulating of noise and air pollution, city managers focus on these kinds of parks. Therefore, the purpose of this study is to investigate factors effecting peoples' willingness to pay for local parks in Tabriz city, applying a Tobit model. A Contingent valuation survey of respondents was conducted between 147 visitors of "Shams", and "Manzarie" parks that were chosen in a random method among other local parks in Tabriz City during 2008 year. According to the results, 69 percent of visitors are willing to pay for using facilities of local parks. The mean of individuals' monthly willingness to pay is calculated about 12, 520 Rials (about 1.2 dollars).Results taken from model estimation, reveal that factors like household' s income, family dimension, visitors' gender, and marital situation, besides their satisfaction of parks social security has positive, and significant relationship, and their range of education has got negative and significant relationship with their willingness to pay.
