The petrochemical industry makes environmental impact and land suitability assessment is important for the petrochemical industry. The objective of this research is to develop a model to analyze the land suitability and site selection for petrochemical idusrty through a spatial-geographical study and environmental palnning and management approach. To this purpose, the land suitability and site selection were performed using the PROMETHEE II and ELECTERE III methods in combination with GIS. These methods were used to undertake the study objective in three stages. Firstly, a review of the literature led to the formulation of analytic land suitability importance for site selection of petrochemical idusrty. Secondly, the major factors influencing the identification of suitable locations for petrochemical idusrty were identified using experts. The outranking methods were used to determine final zoning map. The final zoning map shows about 16% ( 45.207 Km2) by PROMETHEE II and 10% ( 29.207 Km2) by ELECTERE III is suitable for development of petrochemical industry. Sensitivity analysis shows suitable area is consistent with each of input factors in the model. So, this model is suitable to analyze land suitability and site selection for petrochemical idusrty.

The planning literature has passed the prediction, forecasting and exploration of future concepts and has reached to futurology and foresight. Regional development planning is not exempt from this and needs a futuristic approach in order to be used after being planned. Identifying the future uncertainties and the underlying assumptions in the regional development planning by which the long-term plans have been established, is one of the most important main fields in the identification of problems and facing challenges of development documents. Post-planning also deals with the success or failure evaluation of the developed policy and planning in the future time horizon. Assumption Based Planning (ABP) is one of the post-planning methods, which could be used in preparing stable and compatible programs. This research is a combination of documentary and surveying methods in terms of the research type and is analytical and exploratory based on the new methods of futurology science in terms of the research nature which is conducted by a combination of qualitative and quantitative models. Data collection methods and techniques Delphi questionnaire was used and questionnaires are experts in developing and development issues surrounding region During two separate questionnaires have been completed. In this way, the correlation between each strategy uncertainty with mining experts from both questioners (strategies, inventory uncertainty) is calculated. The results show which areas are considered the most vulnerable strategies. Analysis of the results indicate that utilizing the ABP could be implemented in the regional development planning, which helps planners to have a consensus and commitment to the output. Thus, weaknesses and waivers existing in the long-term regional development planning could be identified and reviewed by utilizing the ABP.

Iran needs population growth in order to achieve high weight in the region and world as well as to obviate peripheral threats. Iran's area is so vast that it can accommodate more population than the current population. The country having population density of 46 individuals per square kilometer ranks 162 in the world. However, quality and efficacy are necessary for a population to lead high weight. Therefore, it has been attempted in this research to explain necessity of population growth of the country geographically; and to study optimization of indices for these changes and policy making in order to lead the changes in the framework of the land preparation plans. The research questions are: Which indices are considered as priority from the view point of the land preparation, concerning the population growth; and which areas and provinces are more apt to accommodate more population? General purpose of this study is to consider crucial land preparation indices in population growth policy and to prioritize provinces based on the indices. The research method is descriptive-analytical.

If you don’t know where you’re going, you might not get there. Urban Strategic planning and mainly vision developing is to determine position of the City that wants to reach. Revealing where the city wants to go, instead of continuing to do things in a routine way, city can focus their limited resources on programs that are most effective in achieving the vision. Acknowledging the important role of strategic planning and vision developing in contemporary cities, this paper tries to develop a vision for the city of Saveh in the form of strategic planning process. This research, based on objective is Applied, and based on the nature, analytical – descriptive. In the process of strategic analysis, External & Internal Factors Evaluation Matrix (EFEM & IFEM) is used.Based on the results of External & Internal Factors Evaluation Matrix, the best strategy for Saveh is to protect the stability of city. The final vision of Saveh, consisting six strategic aspects, which are: industrial and economic city, cultural – historical city, Healthy and sustainable city, enabling the processing of agricultural products, College city and Regional Scientific center, and Attractive and lively for sporting and cultural activities and festivals.

Positioning services are generally the activities in which all the features of a particular area are analyzed with regard to suitable land and its relation to the urban and rural functions. Choosing a location requires knowledge and accurate assessments, using appropriate models and tools. In this survey the was conducted in compliance with the standards and features of the site issue Geomorphic region has been examined and is The most important aim identify the status of military centers in the region and analyze environmental conditions and introduce suitable location for the construction military centers. The study is a descriptive-analytical one and benefiting from GIS, evaluates the border areas of South Ilam province and the positioning for the establishment of military centers with regard to the geomorphic and human criteria. therefore AHP model of GIS was used to determine the distribution of military centers of this area. It was finally concluded that %74 of the military centers of this part are placed in proper areas.

The objectives of this study were to investigate and to zoning desertification in a semi-arid region, khomein city using MEDALUS model. In first the study area was divided into four homogeneous land unites based on geomorphological facies. Then, based on input data in MEDALUS model, effective indicators in desertification including climate, vegetation, soil, erosion, groundwater resources and land management were selected. Then, the indices were weighted and the geometic mean was calculated and the map of each criteria was provided. The final map of desertification was prepared based on combination of all maps of each indicator.The results showed that 4.15%, 12.8%, 19.52%, 11.37%, 11.1%, 26.33%, and 14.7% of the study area are in vulnerable, low-intensity fragile, moderate intensity fragile, high intensity fragile, low-intensity critical, , moderate intensity critical, high intensity critical types, respectively.Also, investigation of desertification, relate to land use and land units exhibited that bared land and 1 and 2 land units, that has the most percent of critical type of desertification, is more capable to desertification comparing to other land use type

After movement decision, determination of new location is one of the most critical steps in the process of movement. The reason is that the results of movement, which have several different aspects, are emerged in the long term. The previous experiences showed that the nonchalance in locating the new settlements leads to failure of several movement plans. This study is a descriptive-analytical research. The purpose of this study is to evaluate the movement plans of Larini olya&sofla and Farrokh Abad in Ilam Province in terms of location through method of McHarg, and its needed data have been gathered through fieldwork and text study methods. The findings revealed that from perspective of a large part of criteria, the villages are in the appropriate and semi-appropriate conditions, but the slope of Larini village is inappropriate and Farrokh Abad village is inappropriate in terms of exposure to agricultural lands. Since there are a few situations in which settlements have all of the criteria, it can be concluded that the locations of these villages are appropriate from studied criteria, so the hypothesis is supported.
