Landscape fragmentation, due to the roads construction, urban infrastructure development and other land uses, seems to be in result of the loss of habitat in protected areas. Indeed, Landscape fragmentation causes a huge negative impact on wildlife, including important species. In result, the monitoring and management of protected areas, through the landscape ecology and quantification of fragmentation, will be so applicable. This research aims to quantify the landscape fragmentation in Kolah Ghazy national Park and wildlife refuge. To achieve this purpose, RS and GIS techniques were used to extract land uses in studied area and then landscape fragmentation was quantified using landscape metrics (CA, CAP, TE, MSI, NP, MPS and MNN) in class level. The results cleared that rich rangeland patches have been more integrated, but the incompatible land uses, such as mining, agriculture and urban infrastructure development make these patches to be more far away from each other, so, reduction of incompatible land uses is recommended in the region.

Planners always face a set of spatial conflicts in allocation of land to a particular activity; this implies that a land may be used for two or more parallel applications. Currently in Town and Country Planning programs recognizing priorities in the land allocation process are modeled independently without considering the role of other land uses, and as potential land-use conflicts are an issue that has been ignored. The purpose of this study is to introduce and use the LUCIS model to identify land allocation priorities along with conflict modeling. To implement the model, with using the Python programming language an ArcGIS toolbox has been developed. Due to the developed system, defining inputs, weights and stakeholder priorities, land use modeling will be done automatically. Finally, priorities and also major conflicts in the study area have been identified. Results of this study show that, in addition to having the capabilities of other models in land suitability analysis, LUCIS can properly model existing conflicts. Therefore, it is recommended that a separate part under title "Identification of land suitability conflicts" be specified in the descriptive setting of Town and Country Planning programs.

Azimi, Azadeh
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.

2017
Akbari, Reza
Developing according to foreign investment in South Korea is an economic miracle of contemporary century. The evolution of economic miracle has been accomplished by complete success of spatial planning. The most striking feature of spatial planning in South Korea is its implementation. Using descriptive- analytical method, this paper will seek success procedure of South Korea spatial planning and basic role of government in order to respond three questions: how government of South Korea was able to achieve such successes? Applying spatial planning as a tool in this process, which role government play? And what doctrines have this experiment in order to apply in Iran? Spatial planning of South Korea implement in three scale of master land, regional and urban plan. Urban planning of Korea has a three-tier structure. Urban master plan determine long-term growth path and future image of city in the upper level, urban management plan present program of city with binding rules and objective details in the next level, and the manner of programs and necessary strategies implementation in the third level. Urban management plan, including zoning plan (land use), urban facility plan, Maintenance plan of the city (time-out texture) and detailed plan of regions, is an unique, thorough and so successful sample among different countries and its doctrine is exploitable for Iran which has no land use and urban facilities plan and no sufficient and necessary solidarity in the field of time-out textures and detailed plan. Administrative identical process, preparing all plans by executors and approving lower – rank plans by preparers of upper – rank plans are another striking feature applying in spatial planning system of Korea which is major factors of urban plans implementation.

Parma, Rohollah | Maleknia, Rahim | Shataee, Shaban | Naghavi, Hamed
In order to land cover change modeling and detect to possibility of predict the future trend of Land Change modeler (LCM) was used. VNIR Data ASTER Sensor of TERRA satellite with spatial resolution of 15m for three periods 2000, 2007 and 2016 from Gilan-e-Gharb forests of Kermanshah province were analyzed. Land cover maps of years 2000, 2007 and 2016 four categories: forest cover, pasture lands, agricultural lands and built-up area areas for each of images were extracted. The results of data analysis in the first period (2000-2007) and the second period (2007-2016) showed the greatest increase in agricultural lands and pasture lands have the greatest decrease area. Based on these changes and by taking eight independent variable, transition potential modeling of 2016 was done using Artificial Neural Network. Then by hard predict model and images were classified of first period (2000- 2007), the land cover map in 2016 using Land Change Modeler was predicted. After evaluating the model, 83.09 and 71.10 overall accuracy was obtained for the first and second periods showed the consistency between prediction map and classified map of year 2016. The land cover maps by entering the second period (2007-2016) to Land Change Modeler the land.
