摘　　要：分析了水中泥土含量对水体光谱特征的影响。,对利用水体的光谱反射率计算水体中泥土含量的方法进行了分析 ,找出了用于泥土含量计算的最佳波段。This paper analyzed quantitatively the relationship of mud content in water and spectral reflectance of water, then discussed the factors affecting water reflectance. Through comparing the regression analyses of the water reflectance and the mud content in every band from 350nm to 2 500nm (totally 2 151 bands), the optimum band was found. The method will be of some help to calculating mud content of sea water, river water or flood by means of hyperspectral remote sensing image, and also to estimating the amount of soil erosion.
