摘　　要：以湖北省2001—2011年城市土地利用现状数据为基础,运用信息熵模型、洛伦茨曲线和基尼系数等方法对湖北省城市土地结构合理性进行分析。结果表明:12001—2011年湖北省城市土地结构信息熵和优势度均呈波动下降态势,并逐渐趋于稳定,表明湖北省城市土地开发利用日趋合理,但城市土地内部结构仍有待优化。2湖北省居住用地、公共设施用地、工业用地、绿地和特殊用地分布趋向均衡,仓储用地、对外交通用地、道路广场用地和市政公共设施用地的分布则日益集中。3基于信息熵和基尼系数的研究方法可真实地反映出区域城市土地利用动态演变规律,能准确地阐释区域土地结构的合理状况。Based on the urban land use data of I-Iubei Province from 2001 to 2011, applying the methods of information entropy, Lorenz curve and Gini coefficient, this paper analyzed the rationality of urban land structure. The results showed： （!）The information entropies and equilibrium degrees of urban land structure decreased fluctuating in Hubei from 2001 to 2011, and tended to be stable, showed that the urban land utilization was becoming more rational, but the internal structure of urban land still needed to be optimized. QThe distribution of residential land, land for public tacilitics, irl- dustrial land, greenland and land for special purpose tended to be balanced, the distribution of land for storage, land for transportation system, land fi）r roads and plazas and land for municipal utilities tended to be decentralized. QThe research method based on intforation entropy and Giui cocfficicut could reflect the dynamic evolution rules of regional urban land utilization, and explain the rationality of regional land structure accurately.
