| Abstract: | 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. |
