摘　　要：土地利用结构评价是地理学、统计学支撑的区域可持续发展研究的重要课题。旨在运用新的方法和视角评估土地利用结构的合理性。以常州市武进区土地利用结构作为研究对象,以该区的16个乡镇作为评估的单元,研究区独特的区位和土地利用结构为课题研究提供了天然的实验室。在宏观层面上,运用信息熵理论对区域土地利用结构的有序性、均衡度、优势度进行了分析,结果表明常州市武进区土地利用结构有序性具有明显的空间差异,这种差异跟各板块内部社会经济结构有密切关系;在微观层面上,采用数据包络分析方法,结合武进区社会经济等多项指标,从土地利用结构效率角度,指出武进区各乡镇土地利用结构优化调整方向。研究结果表明:基于信息熵和数据包络分析模型的研究方法可有效克服传统的基于多元统计方法的综合评价技术不足的缺点,能够更加全面地反映区域土地利用结构的差异情况。研究表明:在武进区未来发展过程中,政府应加强土地调控,必须以提高技术效率为主线,加大单位面积土地上的技术投入,优化资源投入结构。各级政府在编制土地利用总体规划时,应当将土地利用结构评估作为规划的一项内容,明确各土地资源类型的布局安排、数量指标和质量要求。另外,此评价方法对区域土地利用结构优化研究有一定的参考价值。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 us
