Intensive Use Evaluation Of Rural Land Based On Entropy Method And Cloud Model

With the development of social economy and urbanization process is accelerating, the rural population scale to urban concentration, the town to extension, which makes more prominent contradiction between people and land. At the same time, in the vast rural areas, rural residential area, land area per capita, the overall layout of the lack of planning guidance control, scattered layout, the internal structure of chaos,"hollow village" phenomenon is serious. Current situation of rural residents has hindered the construction of the new countryside and improve the quality of life of farmers. Rural land of our country’s new rural construction of the intensive degree of land use efficiency and intensive utilization in rural residential area, is the promotion of rural land and orderly, rational and scientific use of an important means.In this paper, the pro the Yellow River agricultural county-Ruicheng County as an example, through the analysis of the population, social and economic statistical data, combined with the1:10000data of land use change survey, topographic map, road map data screening of rural residential land intensive utilization of the main influence factors, the use of entropy method and cloud model weight of getting each influence factor, the weight will be two kinds of method to compute the weighted average as the weight of the evaluation factors, and rural residents in Ruicheng county were intensive utilization evaluation. Using cluster analysis to classify evaluation results, and the evaluation of database and land use status was connected with ARCGIS according to the value attribute; intensive degree size grading, and generate the intensity distribution map. Through the analysis, the intensive degree reached I level administrative village of69, mostly in the ancient town of Wei, Fenglingdu Town, town, township, mainly around the township to the town center village. II the administrative village of51, mostly in the ancient town of Wei, Fenglingdu Town, street south, Southern Town Village Township, mainly distributed in the intensive degree of grade I of the villages around. Ⅲ the administrative village of32, mainly distributed in the intensive degree II villages around, mostly in the mountains to the north, the township have distribution. IV the administrative village of23, mainly concentrated in the town of West Street, Yang Town, Zhang Xiang Township, mostly in the northern mountainous area. According to the actual situation of the evaluation results and Ruicheng County, comprehensive consideration of various administrative village population, farmers in the direction and the village economic development data, combined with geological disasters and the expansion of the road information, residents will be divided into natural village merge, village relocation type, change the old village and village community type four category.
