摘　　要：海岸线是海域变化及陆地变化研究的重要参考依据。为了精确获取我国南海沿岸近十年的变化,这里以TM、OLI数据为基础,利用重复自组织数据分析技术(ISODATA)自动提取海岸线,提取结果采用区域统计分析进行精度验证。研究结果表明,近十年来,我国南海沿岸河流湖泊面积呈快速缩减趋势。The coastline is an important reference for the research of sea changes and land changes.In order to obtain the coast changes of the south China sea accurately in recent 10 years,this paper extracted the coastline automatically basing on the TM,OLI data by iterative self-organizing date analysis technique（ISODATA）.The precision verification of the extraction results was carried out by zonal statistics as table.The results indicates that in recent 10 years,the area of rivers and lakes along the south China sea coast showed a rapid reduction trend.
