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.

Decentralization is the strategy which democratizes of the political system and accelerating to achieve sustainable development، which currently has made the executive government circles become a hot issue. Despite the focused concentration of power and decision-making at the center or top-level officials، decentralization make this possibility to deal with low levels issues and problems of they own directly. Thus، this paper uses the method of descriptive - analytic and with a library collection - documents to review tackles decentralization and define the decentralization policy in Iran before and after the revolution program. Evaluation results show that in spite of decentralization policyIn most cases، development programs، unfortunately، these programs have not been successful and convergence has intensified in Tehran. Reality still shows the focus of activities، services and decision-making centers in Tehran. So the solution is to reduce the concentration of political power - administrative and decision-making and management of the local administration and management of provincial to provide the main way to deal with the approach of decentralization and reform of the governance structure and the reduced concentration of Tehran and the development of developing countries، decentralization

Spatial justiceand geographical justiceasfair distributionof services andamenitiesin order toachieveaharmonioussocietyandone of the socialjusticeapproach. Not proper distributionof services،leads toelimination ofthe justice and willincreasedissatisfaction of citizens from their location. The research method is descriptive – analytical. In order to analysis of how the distribution of services in neighborhoods of six region of Tehran، theLQ، standardized coefficient and VIKOR model is used. Then، using theCopelandmodeltocombinethe results ofthese modelsisdiscussed. The results show that an urban service is not distributed fairly in neighborhoods of this region. So that neighborhoods of Arjanteen – saei and MedaneValiasr in the best position and neighborhoods of Fatemi and Ghezelghale، are locatedat the lowest level in having of urban services distribution. Alsofindingsindicatedthat thespatial distribution of populationand servicesis not fair. Thus،considering the structure of coherent andsystematicof city، attention tothe spatialjustice ofdistributionservicein levelneighborhoods of six regionsanddistributionof these servicesaccording tothepopulation، has made itnecessary.

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

Nowadays as for increasing growth of urban population and then expedite and ungovernable development of cities، many issues and problems have been stand on human societies The assessment of change rate of urban settlements in Sari city in the past half-century shows significant increment of urban lands space over the city. Increment of urban settlements in mentioned area takes place regardless capabilities and restrictions on lands and also ecological capability assessment process of urban development which causes wide range of valuable lands to be destroyed. Ecological capability assessment process of urban development estimates possible utilization of human from land for urban development usage. The present study which is descriptive and analysis and applicable research، is done to achieve designing and using a holistic and flexible model in order to ecological capability assessment of urban development by utilizing ANP. Analysis network process is relatively a modern method in the field of environmental researches that is based on mutual influence of environmental standards and of course wisdom collective judgment. The results of present research led to offering lands zoning map of the under studding area based on Ecological capability assessment of urban development to optimize activities in order to preventing environmental imbalance.
