In the early years, the rising of the sea level, which is a part of natural treatment, destroyed many buildings, arable lands, residential and commercial areas. It seems that the main reason of these destructions is the diminishing of the legal setback efficiency and the proceeding of human activities. The aim of this study is to introduce the appropriate setback for southern coast of Caspian Sea (Gilan province) on the basis of critical levels of Caspian Sea and the results of coastal vulnerability regarding sea level rise. This setback is composed of two parts, vertical buffer and horizontal buffer. In this study, CVI method (coastal vulnerability index) was used for coastal vulnerability assessment. In this method, five variables were employed as in two sub-indexes, natural and human-induced sub-indexes. The final map is divided into four categories, from low to very high vulnerability. Finally the mean distance from the very high vulnerability category to vertical buffer boundary in every district is introduced as the horizontal buffer.

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.

This article has tried to achieve a full understanding of Regional goals of creating new towns and expand the concept of regional balance , survey these towns especially Andishe new town to balance the regional employment and residence space. Datas have been gathered from Library research methods, In-depth interviews and Match data with satellite images,after that these datas analysised with Cross-sectional and triangulation methods. The results are expressed: Andishe new town by absorbing part of the overflow crowd of Metropolitan area and providing employment to its residents and Surrounding urban areas for its part as a planned place has had the most influence to balance the regional employment and residence space

This paper takes a close look at the process of evolution of France’s spatial planning system. The rich background and solid approach of spatial planning in France, introduces this country as one of the pioneers of planning in various levels from local to urban and regional scales. The vision of this country during last decades especially in the field of spatial-physical development planning and monitoring developmental impacts shows a progressive and evolutionary process. Meanwhile, the essence of two levelled approach to planning that defines development at the strategic level and reveals its fruits at the action plan level has made France successful in achieving development goals and preserving its green-fields. In the inner cities with the approval of the new planning law of “Urban Solidarity and Regeneration” there has been a revision in land use planning approach and the mechanism of “Local Urban Plans” preparation has led to the integration of planning process.

The environment impact assessment studies have started with the approval environment impact assessment pattern by sustainable development committee in 1997, but theirs reports are prepared with the different qualities and generally are not comprehensive. Therefore, for considering all aspects of environment, complimentary studis are neccessary. Althoagh many of iran’s dams have environment impact assessment report. they created several problems in their areas. In this study for environment impact assessment of Zablo Dam matrix method was used. Study results have shown that the sum of negative effects are 632 and the negative effects are -524. so that Chahnimeh Four Construction despite of having negative impacts has higher positive impacts on social, economic and biological environment Then Chah nimeh could be implemented.

Every time a visitor sets foot in an ecotourism site, he/she causes a negative impact. this is an unavoidable fact. an ecotourism program initiates many public use activities that will have impacts ,both positive and negative. an Ecotourism Management Plan seeks to minimize the negative impacts.therefore monitoring and managing of visitor impacts are fundamental ecotourism management strategies. If you do not know what effects your ecotourism activities are having on the sites natural environment and the surrounding communities, then you cannot say that you are successful. Monitoring costs General Management Plan and requires trained personnel and assistance of interested stakeholders. The first methods developed to address tourism impacts evolved from the concept of carrying capacity. the more simple concept of carrying capacity-limiting numbers of visitors- can sometimes be used as a solution for mitigating impacts in restricted, small-scale situations .in the survey ,disrupting objects, such as carrying capacity and monitoring of visitors activities.

EIA is one of the acceptable ways for achieving sustainable development goals and as programming tools, it can define potential environmental impact that appears due to executing development projects, and select logical alternatives for solving them. The objective of this study is environmental impact assessment of Ghameshloo highway on Ghameshloo wildlife refugee condition that is located in Isfehan province. At firs by librarian researches we achieved real recognition of environment of area and the identification of all activities in construction and exploitation stage was implemented by literature reviews of project. Finally ICOLD matrix and checklist method was selected for EIA. The result of research shows that by paying attention to crossing this highway from Ghameshloo wildlife refugee and destroying the environment, the implementing of this plan is rejected. The total Values of plan are +182 and -682. According to being more negative impact (353) in biological environment, this environment incurs a loss more negative impacts from implementing this plan, Social environment with 95 values receives less negative impact

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.

Today, Optimization methods has many applications in all different areas of Country planning such as location finding and optimization in Urban Services. In this paper, we review some different methods of optimizations in location finding and Urban Services and. In each of the two areas, we will discuss the application via an example.
