1988—2016年泰国湾海岸线变迁遥感分析

Remote Sensing Analysis of Shoreline Change in the Gulf of Thailand from 1988 to 2016

泰国湾近30年海岸线变迁剧烈。文章基于1988年、1996年、2006年和2016年4个时期Landsat TM/OLI中等分辨率卫星遥感影像数据,开展了近30年泰国湾岸线长度时空变迁遥感监测,并应用数字海岸分析系统(DSAS)计算出4期岸线变迁速率,给出了4个时期泰国湾侵蚀淤积面积状况,分析了岸线变迁的自然因素和人类活动因素。并从岸线增长速率、岸线变迁速率、蚀淤面积状况、岸线类型变化4个方面给出结论。

The coastline of Gulf of Thailand changes violently nearly 30 a.Based on the Landsat TM/OLI medium resolution satellite remote sensing images in 1988,1996,2006 and 2016,the remote sensing monitoring of the coastline length of the Gulf in recent 30 years was carried out and the Digital Shoreline Analysis System（DSAS）was used to calculate the rate of erosion and deposition of the Gulf during four periods,and natural and human factors of shoreline change were analyzed.The conclusions were drawn from the four aspects of shoreline growth rate,the rate of changes coastline,erosion and desposition area,the type of change coastline.
