FINE-SCALE DELINEATION METHOD FOR ASSESSING LAND SENSITIVITY TO DESERTIFICATION

A f1ne-scale delineation method for assessing land sensitivity to desertification includes the following steps: obtaining basic data of a study area and pre-processing the basic data, calculating spatial distributions of a wind erosion factor, a soil moisture factor, 5 a soil texture factor and a vegetation coverage factor in the study area based on the basic data, and comparing and grading with standard values to obtain a sensitivity grade value Wfi of the wind erosion factor, a sensitivity grade value SW1 of the soil moisture factor, a sensitivity grade value K of the soil texture factor and a sensitivity grade value Ci of the vegetation coverage factor, and performing a spatial analysis on sensitivity grading 10 results of each single factor to obtain the land sensitivity to desertification in the study area. The present invention greatly improves the spatial accuracy for assessment results of the land sensitivity to desertification and enhances the ecological space management and control level. 1
