Inappropriate patterns and drastic changes in land-use have caused the severe environmental crisis. Therefore, it is necessary to accomplish any plan in relation to establishment of different activities with respect to land capabilities and land-use evaluation thought. In this study, ecological capabilities and the site selection of land uses in Babolrood basin, Mazandaran province were evaluated. For this purpose, at first, layers and necessary data were collected and then using GIS and systemic analysis method, the ecological capability for each one of uses such as forestry, agriculture, range management, ecotourist, conservation and urban, rural and industry development were evaluated. After that, based on social - economic studies and ecological capability, the final map of land-use planning for study area was prepared. The results show that 73.28 percent of the area is suitable for forestry land use and 5.53, 13.01, 6.87 and 1.31 percent of the area is suitable for intensive ecotourism, extensive ecotourism, agricultures and conservation purposes, respectively.

Nowadays, spatial spread balance in resources and utilities between cities is one of government aims. Utilities spreading balance is binded to their sites in order to all people can access them easily. On the other side, Land Surveying's main goal is regulating human activities in national environment to reach rational exploitation of resources and land capabilities. This goal could be accessed via GIS and its ability in various contexts. In this paper, we focused on spatial spread of Gas industry infrastructures, especially CNG stations in Qom province. First, we evaluated existing CNG cites. We designed special questionnaire containing questions about CNG station's quality, quantity, spatial and services. The forms were filled with drivers and we analyzed them. Also we used GIS to implement CNG cite standards and analyzed existing stations. Also we determined optimal places for CNG station using GIS. Our model includes AHP for weighting layers, a way that uses comparative methods for weighting, and Index Overlay for combining layers with AHP weights. Finally, we categorized Qom province in six categories ranging "Very Unsuitable Sites" to "Very Suitable Cites" for CNG station.

Dalir, Hamid | Ramezanzadeh lasboyee, Mehdi
The geomorphology is an important branch of natural Geography that its goal is promotion of human life, ultimately. The geomorphic processes have considerable impact on human life, and opposing, human activities and behaviors have its impacts on the geomorphologic units and geomorphologic processes, enhancing the above argument. The Gilan county, at its geographic position; embraced by two structural units; the Alborz-Talesh and Caspian sea, appears as a very good open space of morpho-dynamic formations and features. People of this region, on the track of new cultivation and industrial technologic products introduced, initiated a great changes in the Ecosystem, and due to low knowledge of Epigenic flow activities and sea level fluctuations of Caspian sea, they bother toweling and housing in the interior and exterior borders of the sea and rivers. This low knowledge of action and contractions of surrounding natural environment caused huge, bodily and financial damages to them in these hazardous yards.

Ghasemi, Maryam | Kalateh Meymari, Roghayeh | Moeini, Alireza
Inevitably, inconsideration of the population evacuation of villages can have irreparable consequences for the human settlements. Analysis and identification of the qualities of this issue can greatly help planners and decisionmakers in the spatial planning domain to prevent full evacuation of population from rural settlements. The study at hand was an applied research project done using descriptive-analytical approach. The statistical population comprised of villages with less than 100 residents in Khorasan Razavi province from 1986 to 2016. Moran’s local spatial analysis was used to investigate the spatial dimensions, and arithmetic mean and skewed distribution were used to examine the direction and range of distribution. The results showed that in the 1986, 1996, 2006, and 2016 censuses, 92.2, 90.1, 94.8, and 79.9 percent of the villages evacuated in the previous decade have had lower than 100 residents. The results of Moran’s spatial autocorrelation analysis demonstrated that the distribution pattern of villages on the threshold of evacuation during these three decades is cluster-like. Moreover, the results of arithmetic mean and skewed distribution indicated that 68 percent of the villages that are on the threshold of population evacuation are within the oval domain, and except for the 1986-1996 period – when the distribution direction of villages on the threshold of evacuation has been northwest-southeast, the direct has been northeast-southwest from 1996 to 2016.

Water provision service is one of the most valuable ecosystem services that is important as a key service for the healthfulness and management of water resources. In this study, using the Water Yield model of InVEST software, the water supply and demand in Ilam watershed was modeled. The data related to average annual precipitation, annual evaporation and transpiration, root limiting depth, water available for plants, land use map, water consumption and estimation of water provision quantity, basin boundary, and subbasins of the watershed were the inputs of this model. The results of model application showed that in Ilam watershed, 45 million cubic meters of water provided annually, with the highest and lowest water provision volumes being in Arghavan (7 million cubic meters) and Chalimar (802 thousand cubic meters) subbasins, respectively. According to results, there are great differences in the water supply and demand in the subbasins of this watershed. Therefore, planner and policymakers should pay attention to this important issue in the layout of land uses and foresee sustainable use of rich forests in the high yield subbasins such as Arghavan subbasin. The results provided in this study, along with showing the importance of modeling surface water demand and its used in macro-policies of water allocation, can function as a guideline and help the managers and planners of Ilam city to adopt reasonable decisions in managing ecosystem and correctly using land in this area.
