Evaluation on Land Intensive Utilization Based on the Combination of Principal Component Analysis and Entropy Value Method

WEN Xiu-qin et al (Department of Land and Resource Management of China University of Mining and Technology,Jiangsu Key Laboratory of Resources and Environmental Information Engineering,Xuzhou,Jiangsu 221008)  
Taking Xuzhou as an example,using the related land intensive utilization evaluation index system at home and abroad for reference,the evaluation index system including 3 grades,9 indices was established.This evaluation index system was simplified by using principal component analysis to reduce the index number from nine to three.The weight of each new index after simplification was determined by using entropy value method.At the same time,the intensive utilization situations of land in each county(city) of Xuzhou were concretely evaluated by using multifactor comprehensive evaluation method and compared with that in the urban district of Xuzhou.It was found that the land intensive utilization degree of the urban district of Xuzhou was obviously higher than that in each county(city).
