By predicting land use changes, the extent of the expansion and destruction of resources can be determined, and future policies can be pushed in the right direction. The aim of this study is modeling the land use changes process in Mashhad by using Landsat satellite images related to 1989, 2008, and 2014. Initially, based on the hybrid method (unsupervised and supervised classification combination), land uses were classified into six classes. Then, by using the Markov chain, the transmission matrix between 1989 and 2008 was calculated and by applying it in the Markov-CA model, the land use map for 2014 was predicted. In the following, the predicted land use map for 2014 with the actual 2014 land use map was compared with the Crosstab table, and the total Kappa coefficient was 0.91. Accordingly, the accuracy of the predicted Markov-CA model was confirmed. Finally, this model was used to predict land use in 2030. Therefore, by entering the 2014 reference map as the base map, the 2030 land use map prediction map was extracted. The results showed that from 1998 to 2030 there will be an increasing trend in urban and arid lands and a decreasing trend in agricultural lands and gardens. The results indicate that the Markov-CA model can contribute to the design of a sustainable urban system.

Regional Foresight, which focuses on some of the specific land area in a given territory sub-national aims to achieve the desired future decisions, will be operational. This article examines the spatial organization of Settlement systems in Isfahan province And Presentation of the urban system in the horizon 1420.

Based on the findings, Isfahan province in terms of arrangement space systems will face in the next 25 years with five main scenario: Radial scenario, a scenario dismissed Islands, a cluster scenario, the scenario of multi-center, network scenario. Among the scenarios planned, the network scenario we can see the functional spatial integration in the region and the development integrated and balanced space.

Drought changes for optimal operation management of water resources well is the sensible. That's why last round of very extensive research on modeling drought in the world and Iran is and using their water projects and has conducted numerous hydraulic. One of the goals dynamic systems modeling potential policies to improve system performance. Modeling SPI index as an indicator of the country's drought situation stations using radial neural network model for each station was done. Independent variables neural network, relative humidity, temperature and lack of objects, which were selected according to their impact on precipitation. SPI index is the dependent variable. In total period of 42 years calculated by SPI, 12-month and 348 standard score by calculating the SPI 24-month, 336 standard score is obtained for each station. At all stations, ETo values from January to July to December increased and then fell in July to its maximum level reached in all stations. The highest average monthly ETo values in Abadan and Ahvaz stations in July and 18/232 and 16/214 mm respectively happened.

The government system of' Iran is centralized, and because in unitary and single power states, the security of political center (capital) with the total security of political system (National Security) has a direct relationship, the capital movement in Iran becomes important from two aspects; the first is to organize Tehran city and balance urban and regional system of the country and the second is to maintain the political security of the country. Capital movement from Tehran to other cities has been among the issues for more than 220 years but nothing has been done for some reasons. The aim of this paper which is written by descriptive – analyzing and survey method is to identify the main obstacles and the challenges of processing the capital and to present the strategies to remove the obstacles. So 7 elements as Economic, political, security, executive, social-cultural, legal and natural-ecological elements are selected in 55 items and are weighed by the academic elite people. After analyzing the information and using the structural equations model the results showed that the legal factor holding 10 items has the most direct (0/089) and indirect effect and the natural-ecological factor has the least effect (0/033) in moving the capital. Also the results of the network analyzing model for preference survey showed that the experts give priority to executive obstacles which hold final weigh 0/218 and compatibility rate 0/022 stands at the first grade in the priority survey of the obstacles.

Analysis and study of spatial structure and its relationship with regional flows changings is one of the most important issues in regional and country planning. In this paper we try to analyze the spatial structure of South-Alborz (that includes six provinces) based on passengers flow. In order to respond to questions and specific targets we used analytical-descriptive method. Also we used a lot of different statistical tests in ARC GIS and in order to analyze spatial organization of flows, we used another statistical test in UCINET and NET DRAW. This study is an applied and basic research and is a ex post facto. Based on findings the spatial structure of population (as a harmonious whole) has a relationship with passenger flows and these show a lot of forms and trends by time.

Although Iran has a strategic position in the Middle East and there are threats of neighboring and non-neighboring countries, projects and economic infrastructures have been established without proper defensive considerations and are targets for enemy threats and other offensive actions. The present study is an applied and developmental research that aims to study and scrutinize the vulnerability of infrastructures in Ardabil province from the perspective of passive defense. Moreover, analytic network process (ANP) approach is used in GIS environment with elements of physical and biological environment, accessibility, and infrastructures in order to carry out the research. The results of spatial pattern analysis and vulnerability zoning show that the spatial distribution of infrastructure in Ardabil province is cluster type (non-dispersive) and in terms of vulnerability, 7% of Ardabil province is located in highly vulnerable areas which are themselves among the most densely populated places with high amounts of established infrastructures. This is due to poor physical indicators and lack of sufficient managerial, industrial, and military institutions in these areas of the Ardabil province.

The occurrence of natural and human disasters can create heavy casualties in cities and urban areas and such a critical issue makes it inevitable to pay a great deal of attention to the vulnerability and safety aspects of cities and the accessibility to the urban welfare standards from the perspective of passive defense. The geostrategic location of Koohdasht city in Iran and its vulnerability against medium risk earthquakes as well as the strategic defensive role of the city in western parts of the country highlights the vital importance of vulnerability against earthquakes in Koohdasht city. This is a descriptive analytical research with a theoretical- applied essence. In order to achieve to the objectives of the survey, the critical and sensitive uses were identified based on the existing references and the spatial data bank was extracted using Delphi method and based on a survey consisted of 20 pundits. On the other hand, the principle of adjacency was taken into account. Based on the effectiveness of various indicators the combined model of FAHP-GIS was utilized to design the location model and the final raster of the vulnerability of urban infrastructures was provided using Arc GIS software and Spatial Analysis tools through the application of fuzzy overlay functions. The results of the study indicated that about 68 percent of the city infrastructures by meeting the conditions of adjacency between 0.29-0.55 and the vulnerability in the range of 0.45-0.71 fell in the high vulnerability zone.

Creating and preserving large patches in land use configuration and satisfying compactness and contiguity in land use configuration are nature-prescribed and nature-inspired criteria that can be used in land use planning better that before. Accompanying compactness and contiguity as the important landscape metrics in land use planning and land use configuration is close to applying proactive approaches rather than assessing the intense of Human activities' impacts on environment after its altering. To explain how to introduce compactness and contiguity to a land use configuration study, we assume the study area as a matrix that every cell or pixel of the matrix has the color or value that shows the type of land use. In this situation, the compact configuration will be made if the same color or value pixels are located adjacent to each other. With respect to this premise we defined some equations to achieve compactness and contiguity in land use configuration. Finally, we tested the equations in applied case of land use planning in a part of Gorgan Township. We applied hybrid of linear programming and ant colony algorithms for testing suggested method. The results show that the method can be succeeded in achieving these criteria.

The present study aims to provide a solution to optimize land use through multi-objective linear programming, and to solve the conflicts generated in the process using game theory, in two cities of Gorgan and Kurdkoy, Iran. The primary land use planning was completed for seven land use through multi-criteria evaluation and then a first allocation was implanted using MOLA. In the secondary land use planning phase, land use optimization, with multi-objective linear programming was conducted considering economic-social and environmental needs. Environmental requirments such as reducing runoff, non-point nitrogen pollution and soil erosion, were modeled using L-THIA and RUSLE models. For socio-economic parameters job, profit and initial costs were considered. To finalize, a multi-objective linear programming model, was designed. The environmental and socio-economic stakeholders have different needs. That creates conflict in the land use planning process. In the final third phase of the land use planning, game theory was used to resolve conflicts. Environmental and socio-economic players were allowed to play scenarios in triplicate. The results showed the winning changes in land use to the extent that an equilibrium between interest groups was reached.

The purpose of this paper is to analyze the Utility operating radius and service on city parks in Ardabil neighborhood, local, regional and urban level, to investigate the relationship between the distribution of these parks with water levels in the city of Ardabil, including Shorabil lake and Balyqlv river and reviews for distribution park. The data and information used by documentary. To analyze the data, the Thyssen polygons to measure the radius of the functional utility, network analysis to assess radius of the service or coverage of parks, and standard deviation ellipses analysis was used to examine the distribution of parks. The results indicate that the function of the radius of the park in the center of the city were favorable and neighboring areas with high water levels in the periphery of the city were unfavorable. In addition, the test also showed that the standard deviation ellipse for distribution parks in the city of Ardabil in the Northeast, Southwest and more in the direction of the river Balyqlv located. Also, investigating the per capita levels of parks in urban areas determined that, the area 2 municipality per capita is highest among municipality areas and the area 4 municipality has lowest per capita among municipalities.   Keywords
