In recent decades due to growing prices of fossil fuels and environmental pollution as a result of increased energy demand in renewable energy research and study has been considered by researchers. Resource constraints and environmental investments in the electricity sector, including key issues that will affect the process to minimize cost and environmental impact has always been regarded experts. Environmental protection and energy security of the electricity produced by power plants solar power acts emphasized. Iran has a warm climate is semiarid due to the special geographical location and orientation on the radiation belts and desert, The more central parts of the country, especially those are with a clear sky. This increase in sunshine hours and radiation from these regions than in other parts of the world. Therefore study in the construction and deployment of solar sites in the regions of the country can achieve clean energy for residents. This paper uses the capabilities of GIS and models to predict the overall radiation, sunshine hours and the amount of radiant energy receivedin Ardekan township villages. Calculated for each of the months and years, where 7/ 7hours sunny day and average 5/3 solar radiation of more than kilowatt hours per square meter per day were suitable for solar construction sites were identified. And for embedding solar panels priority direction is south and southwest in this place, respectively.

AbstractIn this research through applying Terjung method, climatic parameters of average max and min temperature, average max and min relative humidity, average sunshine hours, and average wind speed of 4 synoptic and 14 climatology stations during 16 years statistical period (1994/3/21-2011/3/20) for each month of the year has been used to evaluate Semnan province human bioclimatic, also Arcmap and AutoCAD map software is used to prepare region maps in different months regarding to height gradient and buffering. The result of this survey indicates that most of the stations located in south, east, and west of the province in months Farvardin (March20-April 19) and Aban (October 22-November 20), and north provincial stations in months Ordibehesht, KHordad, Shahrivar, and Mehr (April 20 until June 20 ,and August 22 until October 21) are in relief confine. Due to dominance of massive climatic phenomena on country's atmosphere and therefore on province, the number of bioclimatic types decreases in cold months. On the other hand when warm months of the year begin the role of massive climatic phenomena decreases and local factors dominate, and therefore the type number increases.Key words:Human Bioclimatic,Terjung, Regionalization, Semnan province

Using of land and natural resources, without considering the environmental and ecological potential, cause the adverse effects and environment degradation. Geomorphic forms and processes are the prevailing natural features and disasters that have caused damage to the humans and the environment via theirs properties. This study investigates the suitable positions of urban settlements development in the Yasouj according to geomorphic forms and processes. In this regard, according to region's natural characteristics, 5 criteria, 15 sub-criteria and 84 classes were identified in order to achieve goals. First, layers slope, aspect, elevation classes, lithology, settlement density, distance from settlement, landuse, road density, distance from road, fault density, distance from fault, density river, distance from river, rainfall and temperature were prepared via basic maps of Yasouj, and were analyzed. Then, these factors were evaluated and were weighed by AHP model. At the end, their raster layers were integrated by Arc GIS 10 software, and final map of urban settlements development in the study area were drawn. Finally, to confirm the results, the final map was evaluated with the current map of the city Yasouj comparatively.The results show that among the effecting factors, sub-criteria of slope, lithology and distance from settlement, with weights of 0.205, 0.129 and 0.104,have been identified as the most important factors in the site selection of Yasouj urban settlements, respectively. According to final map, about %13.46 (37.56 Km2) and %24.44 (68.406 Km2) of the study area are very suitable and suitable for the development of urban settlements, respectively.

Cities forward to develop upon dangerous natural-infrastructures, while there is lack of proper and immediate urbanism law and provision. This condition, moreover to that exceeds the amount of these kinds of dangers, leads to make the most possible victims because of civil population concentration. This process suggests it is serious to determine the dangerous areas and plan for preventing development into the dangerous areas; because determining safe civil areas cannot be applied by the automated civil growth and the intentional targets of house-building dealers. For this reason, this research –using descriptive and analytic method- is seeking to survey Birjand’s physical civil growth and how this city is developed into dangerous areas, and then spots controlling and directing condition of building development growth. The research has been applied by descriptive and analytic method and the results show that not also the physical civil growth has been intensified, but if the civil population concentration has been increased after upgrading the city to province center, while this concentration is distributed without regarding dangerous factors and areas. Therefore, targeted and legal intervention to direct house-building path and refining executive solutions for minimizing damages and victims seem necessary.

The purpose of this study was to investigate the changes in Urmia Lake water level as well as to determine the main factors in the reduction of Urmia Lake water through the multivariate statistical method of principal component analysis (PCA) and its effect on the urban around of Lake. For this purpose, Landsat satellite images besides the data obtained from 29 variables in the statistical periods between 1970 and 2005 have been used. These variables include climate data, and monthly discharge of total basin and tourism situation of basin urban certainly Urmia. From the images, it can be recognized that the coastline has receded, particularly in East and South East, over the past 35 years (1975-2009). By the use of principal component analysis, six components with %78.8 of the total variance among the factors under study were identified as the main factors in the reduction of Urmia Lake water. The discharges in January, February, March, November, and December with %38.8 of the total variance were determined as the first component. Result indicated that The reduction of water level in Urmia Lake will cause many problems spatially in urban that are in distance of 40 KM Urmia Lake and also theirs that have wind direction of west and south west and are in east of lake. Grade of Urmia tourism has changed from one to four.
