Abstract

Introduction: Todays geomorphological studies is the basis of natural resources studies and scrutiny. Accordingly, the plain one of the most important geomorphological forms in arid and semi-dry that have the potential to embrace human population, as well as sources of soil and groundwater and surface water resources are rich. Understanding the processes and mechanisms that enable the user to determine the type of landforms and features as well as the units are remarkably better use of natural and sustainable development is very important. Through the influence of agriculture on the environment, economic growth and food security as though evolving, but very vital role in the economic development of any country. Any use of the land, regardless of differences in ecological and environmental potential to cause adverse environmental impacts such as soil erosion, desertification, deforestation is. Accordingly, the Qorveh County considerable talent in the field of agriculture, and always as one of the most important centers of agricultural production in the province has been. But due to lack of studies on the development of agriculture and the lack of a coherent and systematic planning of land use in this area is not optimal, and also because of the exclusion of farmers in many services and infrastructure facilities and agriculture, small villages and large villages are sending are collapsing. The aim of the present study the feasibility of Development of agricultural lands due to geomorphological features, evaluation of the effect of geomorphological, geological, climatic, hydrological and soil cultivation area on the increase or decrease, as well as geomorphological processes Qorveh and its relationship with cultivated land use and agricultural plain zoning and mapping of it. Qorveh County length and width 47° 38'9" & 35° 16'5" longitude, an area of â â 2480 is dedicated. The city is located in the south-eastern province of North Bijar, from East to Hamadan from the south to Kermanshah and Sanandaj is limited to the West. Methodology: According to the study, this is the way it works after the data collection, extraction and classification to the analysis of data was discussed that parameters, with expert opinion were scored by ANP and a comparison matrix of SUPER DECISION on the application is run and using fuzzy function optimized in ARC GIS software and using the Raster calculator the fuzzy layers on the final score is multiplied and information layers merged together and the final zoning was done FUZZY ANP method. They plan to use overlay zoning and land development feasibility study is prepared. According to studies conducted in this study geomorphological the study area for zoning appropriate in terms of agriculture as well as the results of classification by using FUZZY ANP in view of local experts is the best place for agricultural northern region compared to the other points of interest have been better. Results and discussion: Qorveh range of high altitudes, such as in South Mountain Darvazeh 3162 meters altitude, Ibrahim Attar with a height of 2793 meters and steep valleys such as valley consists of Oriya and Veyhaj that two streams of these valleys and Oriya and Veyhaj shed into plains and it is entered in the northeastern permanent river region Chmshvr. Northern of the region has slowly morphology. Geomorphological feature based on field observations and aerial photographs, elevation profile and slope of the mountains, hills, plains, rivers and hillsides are divided. A large part of the southern surrounded by mountains. Also the central of the studied area covered by the plains and hills scattered. In order to achieve the objectives of the study, data layers (slope, elevation, soil type, geology, land capability, temperature, precipitation, surface water and groundwater quality access) have been studied and analyzed. Water balance of the study area has been investigated then respective map is prepared. For combining layers, with the corresponding parameters of the vector to raster conversion in ARC GIS, the layers were prepared for fuzzy and Fuzzy layers in weight were achieved by the ANP, multiplication and gathered together all the layers and layers of fuzzy merged. As a result of zoning, the area of â â arable will be 1872/83 kilometer. Also the powers and limitations of the geomorphological and land capability set. Conclusion: The total annual rainfall in the study area equal to 837/6 million cubic meters that the 631/36 million cubic meters of it in the form of actual evapotranspiration and 1/5 million cubic meters of it to form of the evaporation of surface water is out of reach and taking into account the penetration factor and with low levels of domestic and industrial consumption 63/5 million cubic meters of water, renewable as they can be considered annually for agriculture. Based on these findings, the amount of annual renewable water for agriculture can be considered as well as favorable areas for agriculture in terms of geomorphology and land capacity was determined that very effectively help to determine how to cultivate and select the type of product proportional to renewable water and land available.
