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.
Key words: Sandy desertification, Warning model
