[Spatiotemporal dynamics of land use and land cover changes in different reclamation zones of Yangtze Estuary].
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.
