【摘要】 长江是我国第一大河流,每年有4.245×108t的泥沙输向大海,影响着长江口南北海域和东海大陆架水域的水体悬沙浓度。遥感是进行悬浮泥沙监测的一种有效手段。在长江口海域,表层悬沙与垂线平均含沙量有着较好的相关性。利用MODIS数据对长江口及南北海域水体表层泥沙浓度进行了反演和分析,较好地了解了长江口的泥沙分布和运移,以及对周边海域的影响。更多还原

【Abstract】 Yangtzi River is the largest river in China.It brings 4.245×108 ton soil and sands into the ocean each year,which greatly influences the suspended sediment concentration(SSC) in the area of Yangtzi River estuary and continental shelf area of East Chinese Sea.Remote sensing technology is one of useful methods to monitor the SSC in the surface water.In this sea area,there is a good relativity between surface water SSC and vertical average SSC.In this article,the author uses MODIS data to reverse the SSC in the area around the Yangtzi River estuary and analyzes the characteristic of its distribution and movement as well as the influence to peripheral sea.更多还原
