摘　　要：基于信息熵和均衡度对长沙市2006-2012年城市土地利用结构的演变进行分析,并运用灰色关联度分析法探讨其与经济水平、产业结构及人口发展3个一级指标及其11个二级指标的关联程度,对各指标与地类变化的关联性进行排序,确定主要的影响因素.研究表明：7年间长沙市城市各职能类土地面积都在增加,增幅有所差异;信息熵总体呈现下降趋势,均衡度和优势度则趋于稳定;经济水平和产业结构的发展是长沙市城市土地利用结构演变的主要驱动力.Grey correlation analysis methods are used to explore the degree of correlation between 3 ifrst-level indicators and 11 second-level indicators of urban land use and industrial structures, and economic and population development. By analyzing the inlfuence of changing of urban land use structure during 2006–2012, key inlfuencing factors are identiifed. The city of Changsha within comentropy and balance degree. Results are as folows: (1) Al land types have been increasing in the past 7 years at different rates; (2) comentropy has decreased overal, but increased in some areas, and the difference between balance and dominance degrees have stabilized; (3) economic and industrial development are the main driving forces behind land use structure in Changsha.
