Identification and Analysis of the Radial Sand Ridges in South Yellow Sea Based on Remote Sensing Technology
摘要
Abstract
This paper aims to understand the rules and changes of the radial sand ridges in South Yellow Sea,as well as reference to the implement of ocean development strategy.Combined remote sensing technique,sand ridge line and axis line,the remote sensing sand ridge line method and remote sensing axis line method are conceived,which are applied to our research region.The sand ridge lines and axis lines in radial sand ridges were extracted and studied based on four TM images from 1992,1996,2000 and 2009.The results showed that:(1) In Huangshayang,the start of centerline changes a little,however the branch point varies a lot during 17 years.The end of centerline moves northward 3,383m.(2)In Kushuiyang,the centerline changes significantly.The main changes are change in branch point nearby start of the line,and change in direction in end of the line.(3) In Xiyang,the centerline changes a little in end section.The west brancn disappeared after 1992,and the left two branches recombined into one branch.(4) A new branch formed in Dongsha,and the sand ridge line changes significantly,the middle of the line becomes like shape S.The line has the trend to move northward as a whole.关键词
