In this research, an attempt has been made to measure agricultural capabilities with two ecological models, which measure agricultural capabilities only with natural criteria and a model based on land preparation, which has a more comprehensive view. In order to collect information, the library method and referring to different institutions were exerted; also, it is an applied and descriptive-analytical research in nature and method, respectively. The agricultural potential of Kohgiluyeh and Boyer-Ahmad province based on Makhdoom model criteria, natural factors such as slope, direction, water level, rain, climate, depth, texture, fertility, and soil drainage using ecological power model have been evaluated, and the next stage is the agricultural capability of the province, based on the land use model, natural criteria include slope percentage, slope direction, soil (depth, texture, fertility, erosion, drainage), amount of water, rain, and weather, and human criteria include access roads, population, unemployment, poverty, and rural areas after evaluating the criteria by twenty experts in this field, the criteria were weighted after validation in the environment (SPSS) and averaging using AHP. The geographic information system environment is combined. By ARDES software and adapting the maps made taking into account the current situation, field observations, and Google Earth, the results indicate that the assessment of the agricultural capabilities of the province based on the land use model (which number is 87.62 according to the 400 points that have been identified obtained (leads to more realistic results than the ecological model) which is 73.58 according to the 400 specified points.

In the course of history, movement of rural homes was a common phenomenon. This phenomenon had several reasons such as natural disasters, provision of better natural resources, war, development projects, etc. Allocation of the new habitat was a vital decision and a critical step in the process of relocation due to its long term affects the lifestyle and livelihood of the inhabitants. Former experiences showed that inappropriate human settlement planning and provision has led to the failure of several relocation plans in the national scale. However, there are guidelines for relocation planners and officials to consider crucial factors and planning criteria. Among them the reduction of vulnerability, proximity to facilities and infrastructures, accessibility as well as favorable topography for construction and ecological capacity are noteworthy. This also includes operational factors for relocating rural settlements such as distance from natural resources, land provision, geographical orientation, percentage of slope, etc. Eslamieh and Andisheh as suburban villages of Sirvan and Eiyvan Cities had several physical and hygiene issues. They were also faced with topographical limitation for expansion due to nearby dam construction and as a result have been relocated into new locations within Ilam province. The purpose of this descriptive-analytical study is to evaluate the rural relocation plans based on the environmental, ecological, spatial, and performance criteria through Model of McHarg. The main criteria include climate, landform, geology, water resources, and infrastructures. The findings revealed that considering several criteria, the villages are in appropriate and semi-appropriate conditions. However, the results also showed that Eslamieh could be assessed inappropriate from the perspective of slope percentage and Andisheh from the perspective of fertile agricultural lands. In total, since residential fabric relatively has most of the criteria passed, it can be concluded that the relocation plans of these villages could be considered successful. Finally, some practical suggestions were proposed for promoting living conditions in these villages regarding the discussed criteria.

Proper programming and multiple use of environment are based on evaluation of the potential of land. Understanding of land capabilities in forests and their classifications can facilitate programming. Site capability classification is based on the understanding of environmental and ecological specifications. In fact ecological land classification is a system that classifies regions or sites with relative homogeneity in variables or ecological resources. Aim of this research is ecological evaluation of capability in forest sites of Nav-Asalem, Lesakooti-Tonekabon and Ziarat-Gorgan, in the Caspian region. The studied sites were selected by on the bases of following criteria: elevation, dominance aspect, level of intervention and availability of primary data. After exploration of ecological resources, analyze of them by (GIS) and data ultimately, the map of homogeneous ecological unites was prepared. Evaluation of ecological capability of the sites was performanced by multi-factor method and Makhdoom model. Finally, the forest site capability was demonstrated in 7 capability classes and their maps were prepared. The results showed that slope percentage, elevation and vegetation density factors are effective factors which are common factors in all models. Distinctive components of specific models are depth of soil at specific model of Nav-Asalem forest, the type of parental material and soil evolution at the specific model of Lesakooti-Tonekabon forest and depth of soil and soil evolution at the specific model of Ziarat-Gorgan forest.
