摘　　要： 顺德区位于珠江三角洲核心地区,正经历着快速城市化的过程,土地资源不断减少与经济快速增长之间的矛盾日益突出。以覆盖顺德区1990年、2000年、2009年3个时相的TM遥感影像为主要数据源,综合利用遥感和GIS技术手段,运用动态度模型定量化研究LUCC,并借助景观格局指数反映顺德区3个时相土地覆盖格局的动态特征,以期更好地对顺德区土地进行规划、实现区域土地资源有效的可持续利用提供理论依据。结果表明:1990—2009年顺德区土地利用变化显著,且以基塘用地大面积减少和建设用地显著增加为主要特点;土地覆盖情况呈现人工景观替代自然半自然景观过程;景观指数分析表明,林地、耕地、基塘用地等均表现为破碎化,顺德区土地覆盖向破碎化方向发展;2000—2009年土地覆盖景观格局的变化趋于缓和,顺德区的城市化发展进入一个较为理性的阶段。 Shunde district is located in the core area of Pearl River Delta,which is experiencing the process of rapid urbanization,and the contradiction between diminishing land resources and rapid economic growth has become increasingly serious.Taking the TM remote sensing images of Shunde district in 1990,2000and2009 as the main data sources,and using the remote sensing and GIS as technology methods,this paper investigated the LUCC with the dynamic degree model quantitatively and characterized the land cover of these three periods with landscape index,which aimed to provide the basis for the better land planning of Shunde district and realize the sustainable utilization of regional land resources effectively.The results showed that the land use of study area changed significantly with the main characteristics on area of dike-pond land decreasing and construction land increasing from 1990 to 2009.There had been a process that the natural and semi-natural landscape were replaced by artificial one.The analysis of landscape index presented evidence of fragmentation development in Shunde district,while forest land,cultivated land and dike-pond land were characterized by fragmentation.From 2000 to 2009,there was a slow change of land cover landscape pattern and the civilization of Shunde district entered a rational stage.
