利用卫星遥感技术，结合地面调查，确定植被状况、地表风蚀状况及土壤状况为沙漠化土地现状程度评价指标选取的3个方面，并给出沙漠化土地程度评价模型；在此基础上，考虑到非沙漠化土地及不同程度沙漠化土地在面积上的组成比例，建立起区域性土地沙漠化总体水平预警模型，应用此模型对我国北方12个省(市、区)以县为区域，进行了土地沙漠化现状水平预警，可为全国防沙治沙工程规划提供参考。

In this paper, the condition of vegetation, the config uration of soil and the feature of earth surface are considered as the three asp ects for selecting evaluation indicators of sandy desertified land, and a mathem atical evaluation model on sandy desertified land was set up. Meanwhile, conside ring the ratio of non-desertified land area and different degree sandy desertif i ed land areas, a regional warning model of land desertification level was given out. This warning model is testified to be applicable in 12 provinces of norther n China.
