摘　　要： 以广东省增城市为研究对象,在GIS平台下,根据1990、2000和2006年遥感影像解译获取的景观动态数据,分析了近16a来增城市景观格局变化规律。结果表明:增城市城市化的迅速发展,使得该市的林地和耕地面积剧烈减少,而居民地面积大幅度增加,景观破碎化程度严重,斑块数目猛增。土地利用的经济效益也有所提高,但由于人口的剧增,人均土地面积在不断减少。 With the help of RS and GIS, the remote sensing images of 1990, 2000 and 2006 in Zengcheng City, Guangdong Province were interpreted. The landscape diversity, degree of evenness, degree of fragmentation and aggregation index were calculated by principles and methods of landscape ecology in order to study the dynamic regularity of landscape pattern of Zengcheng in recent 16 years. Result showed that great changes in landscape pattern had taken place in Zengcheng from 1990 to 2006. The areas of woodland and farmland decreased rapidly, while the residential areas increased rapidly. The fragmentation degree of landscape pattern was aggregated and the patch number increased fiercely. The economic benefit of land use increased to some extent, but per capita usable land was gradually decreasing due to the population explosion.
