Sustainable Spatial Analysis of Rural Settlements around around river ecosystems based on Eco- village model (Case study: Kashkan river basin, Poldokhtar county)

Sustainable development land depends on the sustainability of the rural system and Eco- village pattern can be a new approach an effective role in the sustainable development of the region and, national therefore. Having knowledge of changes in sustainable development and knowing its structure, dimensions and spatial expansion in rural areas are considered as critical parameters for appropriate decision making and planning. The present study is, to analyze and measure the spatial levels of rural sustainability settlements located in around Kashkan River Poldokhtar County. This research is based on purpose, applied and descriptive - analytic research. The required data are obtained in the first stage of qualitative methods grounded theory the interview ways and the second stage of quantitative methods, from the questionnaire. Studying field Poldokhtar County and statistical society research, villages set around on the kashkan. River. For weighing the indicators of the research the F'ANP model has been utilized; data analysis by using the multiple criteria decision- making method VIKOR was done. For classification Rurales study of the levels sustainability was conducted by cluster analysis method using ARC GIS software; for the analysis of the factors affecting the stability linear regression was utilized to measure the effective factors in the final indicator of development. findings of the study showed that of studying 23 villages, 3 village very strong sustainability, 8 village strong sustainability, 5 villages are medium sustainability and the unsustainable villages, there are 7 villages. Most of the rural sustainable situation in central areas of the county that fertile land Caused by river Alluvium has more width and are arranged closer to the center of the county. However, this stability has not happened equally in all indices of sustainability. This situation reflects the imperfect dynamics of the county settlement system in the county (Functional structural aspects). In terms of the application of quantitative models and techniques, this study using F 'ANP model in determining levels of sustainable rural demonstrates the effectiveness of the F'ANP model in geographical studies.
