利用RS和GIS技术，选择1984年Landsat MSS和1992、2000以及2008年Landsat TM遥感影像数据作为主要数据源，结合自然保护区的发展历程对江苏盐城海岸带自然景观的动态变化过程及其驱动力进行了分析。结果表明：1984-2008年的24 a间，盐城海岸带变化特征表现为芦苇滩、碱蓬滩、泥滩等自然景观大幅减少，外来入侵物种米草滩及农田、水产养殖塘、住宅工业用地等人为活动强度较高的景观类型面积显著增加。景观基质构成由自然景观略占优势变成了以农田、水产养殖塘等人工景观为主。景观多样性持续降低，各类景观的分布越来越集中。导致景观格局变化的主要原因是土地利用方式的转变：由传统的水产品采集、粗放式芦苇种植转为高收益的水产养殖、农业生产和住宅工业用地，以及外来入侵物种的扩散。

Variation of landscape pattern can provide key information about human activity effects on landscape. The pa-per mainly deals with the spatio-temporal variation and driving force of the landscape pattern in the coast zone of Yancheng city with the technique of remote sensing and GIS employed. The results indicate:①the area of natural land-scape decreased remarkable, which included reed fields, Suaeda salsa fields, and mudflats. The area of Spartina alterni-flora fields and artificial landscape increased significantly. Spartina alterniflora is an alien invasion species. The majority of artificial landscape is aquaculture ponds and farmland. ② The landscape matrix had changed from the situation that the natural landscape was equal with the artificial landscape to that just the latter was dominant. ③The number of patch and patch density decreased, but average area of patches increased because lots of small natural landscape lost. Coastal landscape diversity degraded. ④ The main reason of coastal landscape pattern change was land use by human, which changed from the traditional aquatic products collection, extensive reed planting into high-yield aquaculture, agricultural production and the resident, as well as the spread of alien invasive species.
