| Abstract: |
| In order to study the distribution of the groundwater level in Aeolian desertification areas, this study used
the MODIS satellite remote sensing data and the remote sensing-mathematical-model of a fusion science research
method, based on the field investigation of the groundwater level, soil moisture and other supporting information in the Aeolian desertification areas . Through the experimental equation of the soil moisture and groundwater level, it proposed a remote sensing model to evaluate the distribution of groundwater level model based on the MODIS image data. And this model was proven in feld in Mu Us Aeolian desertification areas. The analysis result shows that the correlation coefficient of the measured groundwater level and the remote sensing retrieved water level is 0. 868, the error is small, and the result is conformed to the reality. |
