Study On Rural Residential Area Suitability Evaluation And Optimization Of The Layout At Shen Zhou City Based On GIS

Since the reform and open policy, our country rural life level is increasing, urbanand rural construction land area is more and more big, cultivated land occupied isgetting more and more serious, cultivated land protection is faced with the reality ofthe great pressure. At the same time, China’s rural construction is facing long-termlack of corresponding planning theory do his guide, development follow one’sinclinations, lead to layout is chaos, the confusion of cultivated land occupiedphenomenon is serious. Therefore, how to make the rural residential areas spacelayout of the land is more reasonable, prompted him to development is healthy, tosolve the urban and rural land area is unbalanced, supplement the cultivated land, assoon as possible for the new rural construction is a very important practicalsignificance.At present, the domestic research land suitable assessment is on agricultural landand urban construction land, And rural residential areas of space layout of thesuitability of is very small. This paper put Shen Zhou city for example. Land usestatus of case to be made actual survey and research, to land use status cardinalnumber and field survey data as the basis. The city space layout of the rural residentialareas suitable condition is be made evaluation, and according to the evaluation resultstypes are classified, Finally, this paper established the layout of the optimizationscheme. This evaluation system is thinking very thoroughly. method is simple, easy tounderstand, easy to operate, the process is accord with the actual situation. For therural residential areas reasonable layout provides a new way of thinking.The results of the study show that:（1）For a long time the ShenZhou rural residential areas of the city is morenaturally, but many rural building is in their own home fields scattered construction,no form a unified layout scheme. Land for residential areas is generally low efficiency,in general, tend to be scattered. The city of465villages in the countryside is a planardistribution of the town, the area of land to larger and more extensive. The village isclose to the more convenient traffic layout, appear small concentration trend, and take up a small and scattered basic farmland. The internal structure of the village waschaos, and is the lack of infrastructure, the road sclerosis rate is low, the waterdrainage and garbage disposal facilities is less or not, the village of leisure,entertainment, health in public places is less, and unable to meet the farmers’ modernway of life.（2）The rural residential areas of the ShenZhou county of the layout of thesuitability of evaluation result is divided into five level, including layout suitabilitygood regional area of57552.26hectares， accounting for46.62%of the totalevaluation area, distribution in the town, but the northern part of the urban distributionarea birth is the most； Layout suitability medium area is18820.61hectares,accounting for16.00%of the total area, distribution mainly in the southeastern part ofthe evaluation area；Layout suitability of poor area occupied area is6690.90hectares,accounting for5.31%of the total area, they are mainly distributed in the evaluation ofregional south; Layout suitability of poor area is714.18hectares, accounting for0.58%of the total area, they scattered layout, village far away from the center, thetraffic is not convenient.（3）The ShenZhou county rural residential areas of space layout and adjustmentscheme is local162village, accounting for34.54%of the village; The village centeris57, accounting for33.48%of the village; The reserve number is101villages,accounting for21.54%of the number of the village; The village is moved and49,accounting for10.45%of the village.
