| 摘 要： | 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为沙漠化土现状程度评价指标选取的３个方面，并给出沙漠化地程度评价模型：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规划提供参考。

| Abstract: | In this paper, the condition of vegetation, the configuration of soil and the feature of earth surface are considered as the three aspects for selecting evaluation indicators of sandy desertified land, and a mathematical evaluation model on sandy desertified land was set up. Meanwhile, considering the ratio of non\|desertified land area and different degree sandy desertified 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 northern China. |
