摘　　要：以长江三角洲2000年和2014年的2期土地利用空间数据为基础,应用经济学中的洛伦茨曲线和基尼系数,进行长江三角洲2000—2014年的土地利用结构时空变化研究,分析得出:在时间上,长江三角洲土地利用结构变化中起主导作用的土地利用类型是耕地、林地、城镇用地和农村居民用地;在空间上,耕地、水库坑塘、农村居民用地和城镇用地分布比较均匀,其次是林地、河渠、草地、其他建设用地和滩地,湖泊、未利用土地和滩涂距绝对均匀线较远,说明在长江三角分布极不平衡,差距悬殊.15年间,耕地、林地、草地和河渠在向不均匀方向发展,湖泊、水库坑塘、滩涂、滩地、城镇用地、农村居民用地、其他建设用地和未利用地恰好相反.Based on the land use data of Yangtze River Delta region in 2000 and 2014 year, we introduced the concept of Lorenz curves and Gini coefficients to analyze the temporal-spatial variation of land use structure. The results showed that, with temporal change, cultivated land, forest land, urban land and rural residential area played an important role in the variation of land use struc- ture. In spatial chang, cultivated land, the reservoir and pond, rural residential area and urban land were dispersed, followed by forest laud, rivers and canals, grass land, other construction land and tidal flat. Lake, unused land and beach land were farther away from the uniform line and were extremely unevenly distributed in Yangtze River Delta region. Cultivated land, forest land, grass land and rivers and canals were converted to be uneven in 15 years of study period, while lake, the reservoir and pond, beach land, tidal flat, urban land, rural residential area, other construction land and unused land were reversed.
