遥感技术在江苏沿海滩涂动态变化分析中的运用

Application of remote sensing technology in analysis of dynamic variation of coastal shoal in Jiangsu

利用多时相遥感影像(1979年,1989年,2000年及2007年的TM/ETM影像)和1995年地形图为数据基础,对江苏的海岸线、滩涂进行了遥感解译,对沿海滩涂资源近30年来的演变特点和趋势作了定量分析,对岸线的稳定性进行了划分并分析了沿海滩涂变迁的主要因素,为合理、有序开发利用滩涂资源及后期该区域的经济发展和生态环境的变化提供可靠的证据。

Based on the multi-temporal remote sensing images（TM/ETM images in the years of 1979,1989,2000 and 2007） and topographic maps in the year of 1995,the authors conducted remote sensing interpretations on the coastal line and coastal shoal in Jiangsu and quantitative analysis on the evolution characteristics and trend of the coastal shoal resources in the latest 30 years,plotted out the stability of the coastal line and analyzed the main factors of coastal shoal variance,provided reliable grounds for the utilization of shoal resources and the future development of the local economy.
