Based on the TM and ETM remotely sensed images of Yangtze Estuary in 1987, 1995, 2000, and 2006, and by using RS, GIS, and mathematical statistical methods, this paper analyzed the dynamic changes of land use and land cover in different reclamation zones of the estuary. In terms of relative area occupied by each land use type, grassland showed significant spatial differences (P < 0.05) among the reclamation zones, while greenhouse land and paddy field showed significant temporal differences (P < 0.05). After eliminating the factor reclamation time, there was no significant difference in the land use diversity index among the reclamation zones. In terms of land use change rates, no significant spatial difference was observed among the reclamation zones, while greenhouse land and built-up area showed significant temporal differences. In terms of land use intensity and transformation direction, different reclamation zones had no significant differences. The land use dynamic changes in different reclamation zones of the estuary were mainly affected by reclamation time.
基于1987年、1995年、2000年和2006年长江口的TM和ETM遥感影像，运用遥感、地理信息系统和数理统计方法，分析了河口不同围垦区域土地利用与土地覆盖的动态变化。就各土地利用类型所占相对面积而言，草地在各围垦区域间存在显著空间差异（P<0.05），而温室用地和水田存在显著时间差异（P<0.05）。剔除围垦时间因素后，各围垦区域的土地利用多样性指数无显著差异。就土地利用变化率而言，各围垦区域间未观察到显著空间差异，而温室用地和建成区存在显著时间差异。就土地利用强度和转化方向而言，不同围垦区域无显著差异。河口不同围垦区域的土地利用动态变化主要受围垦时间影响。
