| 摘 要： | 文章针对当前水资源不合理利用和水污染所造成的水资源危机的问题，以数学建模思想为指导，从含沙水体光谱特征出发。根据光谱传播的物理性质，建立了关于遥感影像与含沙水体光谱特征间相互联系的数学模型。即遥感图像灰度值与出水反射率的相互关系。最终实现对内陆河流湖泊的含沙状况进行实时、动态、快速的监测。

| Abstract: | Currently,the irrational use of water resources and water pollution are very serious problems.In this paper,basing on the idea of mathematical modeling,starting from the spectral signature of sandy water bodies,and according to the physical property of radiation spectrum,we establish a mathematical model for the relation between remote sensing image and the sandy water bodies'spectral signature,i.e.,the relationship of reflectance and the DN value of the remote sensing image.Finally,we realize to monitor the turbidity of inland river and lake timely,dynamically and speedy. |
