2014
Seidaiy, Sayed Eskandar | Azadi, Younes
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.

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.

Evaluation of land capability is a way of knowledge of nature and preventing its destruction. The Logic scoring of preference method is one of the new approaches in land evaluation. This method consists of three main components: the attributes tree, the preliminary criteria and the aggregation structure. Criteria and sub-criteria of the conservation model, criteria weightings and standardization functions were determined by the resources reviewing, environmental attributes of the area and consulting with local experts. Then, the decision tree is formed, after that, the sub-criteria, criteria and attributes were weighted. Their replacement capability was determined. Replaceabilityorsimultaneitymeans identifying importance of criteria and sub-criteria in decision making. So, more or less effect of criteria was determined on the final decision by the ranges of positive and negative numbers. Aggregation of criteria and sub-criteria were done by Weighted Average Power Method. Conservation maps were prepared with two scenarios without_with the replaceability criteria. Scenario result of without replaceability shows the region's conservation value better than the replaceability scenario. The research results showed that rivers and aquatic ecosystems, scarce native plants and Mountains with high slope and shallow soil are sensitive to degradation. The proposed GIS-based LSP method is an enhanced MCE approach that represents an excellent tool for discussion and deliberation among stakeholders, decision makers, land-use planners and other experts.

2011

In this research, first was identified suitable regions (considering ecological indexes) for intensive and extensive outdoor recreation and their various degrees using the usual tourism ecological model and applying GIS. Results showed that 297.223 hectares of park area have class 1 of extensive outdoor recreation potential, 86.465223 hectares class 2 of extensive outdoor recreation potential, 1.126 hectares class 1 of intensive outdoor recreation potential and 137.417 hectares class 2 of intensive outdoor recreation potential and 16.212 hectares of park area is protection region. In the next step, with field surveys wefound that one of problems that increases rudeness in park nature is absence of attention to all effective factors of outdoor recreation potential of the park. Thus with refer to field, recorded points of water resources, recreation facilities, access road and tourist attractions using GPS these non-ecologic factors as positive informational layers were mixed with primary outdoor recreation capability map and final outdoor recreation capability map was maed. Final results showed that although the usual method is very efficient, it most, because don't consider all effective factors of recreation and enter other informational layers except ecological factors
