Yongjing County natural economic and social conditions and land usein-depth analysis on the basis of building a county land economical and intensive useof the total target layer, economical and intensive use of agricultural Land and landfor construction of economical and intensive use of the rule layer, land investmentintensity, the intensity of land use, land-use efficiency, structure and layout of land useand land-use ecological benefits for the child rule layer, including32index layer ofcounty land economical and intensive use of the comprehensive evaluation indexsystem. Yongjing County land use in determining the weights of evaluation indexesand the actual value on the basis of economical and intensive use of the overall levelof,2005-2010Yongjing County land use of economical and intensive level of changeand the townships of land conservation, intensive level of use of spatial differences,Yongjing County land for construction potential estimates were evaluated.This study adopts the evaluation of the efficacy function, entropy method, principalcomponent analysis and evaluation Yongjing County land economical and intensiveuse. The obtained Yongjing County Farmers’ land economical and intensive use ofcounty land conservation, and intensive use of the comprehensive level ofcontribution is less than the economical and intensive use of land for construction.The whole evaluation system Yongjing County land economical and intensive use ofthe overall level of land use intensity, land utilization, the center for land inputintensity and land use structure and layout. Obtained through the comprehensive evaluation Yongjing County, intensive use of land value0.81belongs to the moderateeconomical and intensive use stage; comprehensive evaluation value of each indexlayer, the lowest for land use efficiency, the efficiency of land use "Land of inputintensity <land use structure and Layout <land use intensity; Yongjing CountyFarmers ’land economical and intensive use of land for construction of economicaland intensive use of the Comprehensive Evaluation of the value of0.49>Comprehensive Evaluation of the value of0.33; Yongjing County Farmers’ landconsolidated in this study, statistical score of0.70Comprehensive land forconstruction score of0.76, which can be seen in the low intensive use stage YongjingCounty Farmers’ land, construction land use in the moderate economical and intensiveuse stage; through statistical indicators, land use intensity of the highest scores.efficiency of land use lowest score. In this study, two methods Yongjing County landfor construction of economical and intensive use potential evaluation, drawn YongjingCounty existing land for construction of economical and intensive utilization of thepotential scale of1158.13hectares, and that the Yongjing counties intensive use ofland for construction or part of the potential Yongjing County to carry out theconstruction of tourism in the future with the use of more accurate guidance of theplanning target.
