With the topographical data of river network in 1980s and at the end of 1990s, the characteristics of fluvial process after 1980s were analyzed by comparison of the variations of the talweg and capacity of the main river courses, the average altitude of the riverbed, and the width-to-depth ratio of riverbed profiles.
总结了20世纪80年代前珠江三角洲网河河床演变特征,并采用80年代和90年代末的河道地形图,通过对比珠江三角洲各主要河道的深泓线、平均河底高程以及河道容积、河床断面宽深比的变化,分析珠江三角洲80年代后的河床演变特征。
The nautical charts in 1966 and 1977, Synthetic Aperture Radar (SAR) images in 1995 and 2000,and Landsat images since 1986 and survey data of beach profile in 2000, were interpreted and analyzed to obtain the positions of main tidal channel talwegs.
利用1966年和1977年海图、1995年和2000年合成孔径雷达影像,结合1980年以来的陆地卫星影像和2000年的岸滩实测剖面资料对南黄海辐射沙洲区主要潮沟的位置进行了解译与分析,得出上述4个时期研究区内主要潮沟深泓线位置图。
