以多期遥感影像数据作为数据源（ MSS／TM／ETM＋／OLI／SPOT－5），借助GIS和RS技术，分别提取了乐清湾1981，1991，2001和2013年4个时期的海岸线矢量数据，并对其32年间的时空变化特征进行了分析，探讨其驱动因素．结果表明：受人类活动影响，近32年来乐清湾海岸线变化十分剧烈，自然岸线减少了105．5 km，人工岸线比例从1981年的22．2％增加到2013年的73．9％，陆域面积增加了90．83 km2．不同岸段的岸线变化也极不均衡，岐山—华秋洞岸段变化最为剧烈，陆地面积共增加了39．96 km2，以围海养殖和城镇与港口建设用地为主．乐清湾岸线变化可能造成滨海湿地生态系统的退化，生物栖息地场所减少，海岸带环境问题增多．

To analyze the characteristics of spatial and temporal variation during 32 a and explore its driving force, multi-source remote sensing data were selected as data source ( MSS /TM /ETM+/OLI/SPOT-5 ) , based on GIS and RS technology, four periods shoreline (1981, 1991, 2001 and 2013) of Yueqing Bay were extracted.Influenced by human activities, the shoreline changed intensively in Yueqing Bay.In recent 32 a, natural shoreline reduced 105 .5 km while the proportion of artificial shoreline increased from 22 .2% to 73.9%in 1981—2013, and land area increased 90.83 km2 .Changes of shoreline in different area were also very uneven, shoreline from Qishan-Huaqiudong was changed dramatically with the land area increased 39.96 km2 , and took reclamation farming and town and port construction land priority.Changes of Yueqing Bay shoreline might cause degradation of coastal wetland ecosystem, reducement habitat sites, increasement of coastal environmental issues.
