| 摘 要： | 悬浮泥沙浓度是衡量水质的重要指标之一,估算其泥沙浓度及获得其在空间和时间上的分布信息对于保护与管理湖泊生态系统是有利的。该研究以鄱阳湖区域为例,利用MODIS。感影像,并结合反演模型对鄱阳湖区域的悬浮泥沙浓度进行反演。结果显示：2010年鄱阳湖悬浮泥沙浓度呈明显的时间和空间分布特征。

| Abstract: | Suspended sediment concentration was one of the important parameters to evaluate water quality,evaluating and obtaining the information of temporal and spatial distribution was benefical to the management and protection of lakes ecosystem. Taking Poyang Lake area as an example, combined with inversion model,Poyang Lake area suspended sediment concentration was inversed by using MODIS remote sensing image, The results showed that the suspended sediment concentration of Poyang Lake had obviously temporal and spatial distribution characteristics in 2010. |
