摘 要：
The land degradation has been attracted more and more attention in China. It is becoming a challenge for scientists to find effective measures to control the land degradation. In this paper, taking Fujain province as a case study, we reviewed the spatial pattern and correlation of major land degradation: damage of cultivated land, soil pollution, soil erosion, and soil leanness. The concept of land degradation danger degree was proposed, and the social and economic factors, which influence the land degradation danger degree in Fujian, were analyzed, 6 important social and economic index were selected. Supported by certain mathematical models, combining with the main types of land degradation, a regional classification of land degradation danger degree in Fujian were developed based on the technology of geographic information system(GIS),and the characteristics of each sub-region of land degradation danger degree was described.
