Abstract:

The evaluation of land use structure is an important issue of region sustainable development research supported by geography and statistics The purpose of this study is to judge the rationality of land use structure from new perspectives and method The theory of information entropy and date envelopment analysis （DEA） has been employed A case study of evaluation of land use structure for Wujin district，China in 2010 is provided to illustrate the application of this research model The study area is located within the Yangtze River Delta near the southeast coast of China Nowadays，Wujin district is the place with the fast industrialization and urbanization in China Hence，the urbanrural land use structure of this area is complicating and rapidly changing As a result，this area becomes an ideal laboratory for the research on evaluation and optimization of land use structure In this article，16 towns affiliated to Wujin district were the research unit At the macro level，the regulation degree，equilibrium degree and dominance degree of regional land use structure were analyzed by use of information entropy model The result showed that land use structure had a significant spatial difference in Wujin District The disequilibrium between the development of industry and agriculture was so common in all of the 16 towns This difference was closely related to the economical and social structure of each research area At the micro perspective，land use efficiency was analyzed by use of data envelopment analysis model The optimization and adjustment direction in land use structure were pointed out from the view point of land use efficiency The result showed that the research method based on information entropy and data envelopment analysis model could effectively overcome the drawback of traditional evaluation techniques Compared with the traditional methods，the new optimization model based on a structure of the multicriteria factors and objective weighting method could evaluate the rationality of land use structure more comprehensively By adopting an overall point of view，government should vigorously intensify the land control Governments at all levels should，in the process of compiling the overall planning for land utilization，list evaluation of land use as one of the contents of the planning，expressly define the arrangement for the layout，quantum targets and quality requirements of land use It is necessary to improve technical efficiency，increase technical inputs on the unit area of land，and optimize the structure of resource inputs in the future development of Wujin The research method in this paper will be able to provide a certain reference value for optimization of regional land use structure
