Review on information extraction for suspended sediment and its spatial distribution of Zigui-Badong in the Three Gorges Reservoir area

摘要：

Since the Three Gorges Reservoir has been used for water storage,the velocity of the Yangtze River and its tributaries in the reservoir area is becoming slower,so weakening is the hydrodynamic,which caused changes of suspended sediment concentration.Using CBERS images of the reservoir area,and working through some image processes,including water extracting,binary treatment,suspended sediment inversion and density segmentation,we can obtain that the distributed characteristics and variation trends of suspended sediment in the reservoir area,which can be useful to solve some other issues of study area.
