摘　　要：土地集约利用评价作为重要的土地资源管理工具,对于土地资源的可持续利用和促进经济、生态、社会的协调发展具有重要意义。本文从宏观尺度进行城市土地集约利用情况的分类识别与横向比较研究,以江汉平原地区21个城市中心城区为研究对象,通过遥感解析与地理信息数据分析方法批量识别城市建设用地,在此基础上,构建多层次多维度的土地集约利用评价指标体系,运用熵权法以及K-means聚类分析方法对上述中心城区土地集约利用程度进行分类,揭示市级城市、省直管城市、县级城市等不同行政级别管辖差异下中心城区土地集约利用的分异情况,为城市因地制宜制定土地集约利用政策提供依据。The evaluation of intensive land use is an important tool to evaluate the degree of land intensive use.It is of great significance for realizing the sustainable use of land resources and promoting the coordinated development of economy,ecology and society.In recent years,research on the evaluation of intensive urban land use at home and abroad has mainly focused on urban agglomerations,provinces,cities and other scales in terms of research scale,and mainly involves developed coastal cities or provinces with strong economic foundations.There is a lack of research on cities at different administrative levels.A comparative study of intensive land use.In fact,under China’s land development rights allocation framework,which centers on the level-by-level allocation of land use indicators,cities at different administrative levels enjoy unequal land development rights.Specifically,cities with higher administrative levels have a stronger say in the allocation of land use indicators,and can obtain relatively more indicators for new urban construction land and fewer indicators for cultivated land protection tasks.However,it remains to be revealed what the differences are in the degree of intensive land use in cities at different administrative levels,and whether high-level cities with more say in urban construction land indicators show higher degrees of intensive land use.Therefore,this article selects Xiaogan City,Jingzhou City,Jingmen City,Tianmen City,Xiantao City,and Qianjiang City in the Jianghan Plain of Hubei Province as the research area.Xiaogan City,Jingzhou City,and Jingmen City are prefecture-level cities,and Tianmen City,Xiantao City,Qianjiang City is a city under the direct administration of the province.A total of six cities,nine county-level cities and the central urban areas of six county towns are used as research samples.From a macro scale,the classification,identification and horizontal comparison of intensive urban land use are studied,and through remote sensing analysis,use the geographical informatio
