摘要
分析土壤含水性与土壤反射光谱的函数关系以及遥感像元光谱中土壤光谱与植被光谱的组合关系；根据处于平衡状态时地表层含水率与表层以下不同深度土壤含水率的函数；提出在ＧＩＳ支持下采用多波段卫星数据，在剔除植被影响后定量计算表层土壤含水率。
By analysing the reflected spectrum composing of soil, water and vegetation in remote sensing data, and according to the functions between the soil moisture of surface layer and underground layer, the authors put forward the theory and method of calculating soil moisture under ground which using multispectral landsat data, having eliminated the effect of vegetation, quantitatively calculates moisture content of surface soil and then reckons the soil water content under ground.
