浙江省沿海由于滩涂围垦引起海岸线的剧烈变迁，研究海岸线的变迁规律对生态环境安全、经济发展具有深远意义。采用1964年CORONA影像、1984年和2003年TM影像、2013年Landsat 8影像作为数据源，将浙江省慈溪市作为研究区域，以GIS和RS技术为支撑，采用人机交互方式提取了4个时期慈溪市海岸线，并结合其它资料，对海岸线变迁进行了分析。再利用TM和Landsat 8影像提取了慈溪市1984年、2003年以及2013年3个时间段的NDVI值，根据NDVI分析了慈溪市植被生态情况以及其变化趋势。

As the tidal flat reclamation in Zhejiang causes severe changes in coastline , the research on coastline change has far -reaching significance in ecological security and economic development . With CORONA image in 1964 , TM images in 1984 and 2003 , Landsat 8 image in 2013 as the data source and with Cixi City , Zhejiang Province as the study area , as well as supported by the GIS and RS technology , the present paper extracts four periods of coastlines in Cixi . Then combined with other information , analyzes the coastline changes . From TM and Landsat 8 images , this paper extracts the NDVI ofthreeperiodsinCixi . After that , this paper analyzes vegetation ecological changes and trends analysis based on NDVI . This article provides an important scientific basis for research on trends of coastline and its impact on the ecological environment in coastal areas of Zhejiang .
