Development is multilateral process that Different factors and variable such as political, economical, social, security and geographical have affected on this process. Although the role of these factor differs from one area to others. In the most developing countries, process of development is not fair. So that unfair development is one of feature and developing country. This matter is clear in Iran. So, some areas have suitable situation, in which, development index are good and environmental facilities are optimum. But in some areas the case is vice versa despot of natural facilities.Goal of this research is to identify reasons and barriers of Abou Musa Island' s non-developing. This research is a study for thesis of M.S. Title and this research is study of facilities and bapiers of Hormozgan province, development and its effect of national security.

Subterranean canals are part of underground water in dried and half dried regions in IRAN and gonabad for reason, mythological numerous subterranean canals, like ghasabe subterranean canal in this area is important. An accomplished study especially since 1982 up to day indicates that two original element in decreasing subterranean canals water. One improper operation is caused reducing the water level of underground sources and another phenomenon of universe climate' changes which its effect has appeared as severe drought in our country and is effectively the cause of decreasing water and reduction of underground water.Analyzing the descriptive correlation between climate and water field has been attributed and used by statistical method in this study. It has been recognized that there is a relation between cultivated level and water canals, so that during 1998 to 2007 that is nine years 23% water supply and %59 cultivated level has decreased as well and that 14% the immigration of villagers have been caused by decreasing canals water.

River basins especially in arid and semiarid lands including Iran and neighbor countries have always been populated and civilized.Increasing population and as a result pressure on water and soil resources in recent era, within change and improvement in water supplying techniques and cultivation systems, has caused more attention to these rare resources in our country. Hence, the management of natural resources and protecting plans in new methods has increasingly gained more importance and necessity. In this research, the impacts of ZRRP have been evaluated through a qualitative method. The results obtained from this research showed that the performance of the project's measures in reducing the number of floods and increasing the area under cultivation were excellent and these activities had a considerable impact on crop yield and economic condition of the farmers.92 percent of the respondents agreed that the project had considerable economic impacts for the farmers, reducing the costs of land management and expanding the available land for cultivation, and increasing crop yield and the land price, whereas the effectiveness of the project on other factors studied such as the social factors was found to be statistically insignificant.

One of the issues which is constantly encountered by regional and urban planners, is related to that of unequal growth and development of the regions and cities, such that by having a look at the spatial distributi6n of activities in the regions and cities, it becomes clear that such activities have been distributed unequally. In the present study the attempt is to analyze spatially the urban development indicators in regional metropolis of Iran. In order to achieve this crucial issue, by exploiting the techniques of the central index, Mac Granahan and Preston, by taking advantage of twenty variables of urban development and five population variables, gathered from regional metropolis of Iran, try to analyze and assess the situations of services in these cites. The results of the study, by using the technique of Mac Granahan show that metropolis as Tehran, Mashhad and Isfahan are in the first to the 3rd rank, while cities as yasuj and semnan are in the 29th and 30th rank. The finding of the study by taking advantage of Preston technique show that the indicators of development in regional metropolis of Iran doesn't have an equal trend and as the charts show where the charts slope alters and where there's a break in the charts slope, the change on the surface of the centrality of metropolis, has certainly occurred.

Frost is one of the most damaging natural incident which influences on various aspects of human life, i.e. economic issues, social issues, transportation, buildings infrastructures, and agriculture. Assisting to frost seems to be a necessary issue especially in agricultural issues. The aim of this research is the zoning of frost intensity in Yazd province. According to the point that frost in Iran and Yazd province causes numerous damages to the agriculture section, in this research it has been tried to examine the frost intensity and passage zero temperature and below. To do so, we have used daily Min Temperature data of 14 Yazd weather stations from, 1371 to 1386. Transition dates of zero and below zero temperatures also show that normally and by stations separation, zero transition date is from Aban outset to Azar middling, -2 transition dates is from Aban ending to Dey outset and for -5, from Azar middling to Dey middling.

One way to decrease the income gap in cities is to establish Service units that will lead to employment and income distribution. Rood-e-hen is located 45 kilometers east of Tehran metropolitan, which due to it's appropriate climate condition, construction of villas to spend leisure time in there and university development, the occupied population share in service Section from 48% in 1987 has increased to 79.3% in 2008 Research method: in this article by parametric and a parametric statistical method and field visits the role of service section at incom distribution has been analyzed. Findings: in comparison to the past, there- is a meaningful difference at income average, family, Consumer goods, food and clothing expenditure among employees of service section and other section and increase of satisfaction of clerks in service section.

To assess heat stress and thermal comfort conditions in seven southern coastal and insular cities of the country including Abadan, Boushehr, Bandar Abbas, Bandar Lengeh, Chabahar, Jask, and Kish, we used Heat Index (HI) method on synoptic hours, monthly, and annual basis for 30 -year period 1976-2005 in these cities. Our results showed no thermal stress for Abadan and Boushehr in January, February, and December, and for Bandar Abbas in January. For two selected months of February and August, we found lowest and highest Heat Index for the former month in Abadan and Chabahar respectively and for the latter month in Chabahar and Bandar Lengeh respectively.Furthermore, based on annual averages of Heat Index in under study seven cities, Abadan has lowest Heat Index and Bandar Lengeh and Jask have highest Heat Index and in cases with human prolonged exposure and/or physical activity they arecategorized as extreme caution and danger respectively.
