苏北废黄河三角洲岸线变迁与海岸冲淤动态遥感监测

近几十年来,我国的砂质、淤泥质海岸正呈现侵蚀加剧的演变趋向。随着卫星遥感数据在光谱、时间和空间分辨率方面的不断提高,海岸侵蚀和淤积监测具备了精度越来越高的数据源。在前人研究的基础上,以废黄河三角洲海岸为研究对象,利用遥感技术和野外实地调查对海岸岸线变迁及冲淤动态进行了研究。研究表明:遥感技术在岸线变迁、侵蚀淤积监测和预测方面具有其他技术无可比拟的优势,在海岸带地质环境监测中的应用已成为具有实用价值的技术。

Remote Sensing Dynamic Monitoring of Coastline Chang and Erosion and Deposition of the Abandoned Yellow River In Northern Jiangsu Prov.

The sandy and silt quality coastal of the China is showing evolution trend in decade years. Based on the improvement of the spectral, temporal and spatial resolution of the satellite remote sensing data, and provide increasingly high accuracy of remote sensing data sources to monitoring the coastal erosion and deposition. Base on previous study, the writer using remote sensing techniques and filed surveys for study the coastline change and the erosion and deposition of the abandoned Yellow River in the northern Jiangsu province. The result shows us that using multi-temporal remote sensing data in coastline changes, erosion and deposition monitoring and prediction has the unparalleled advantage of other technologies, and has become a practical technique in monitoring of coastal geological environment.
