科尔沁沙地破坏起因及恢复途径

Destruction Causes of Korqin Sandyland and Approaches to Its Restoration.

科尔沁沙地是我国北方半干旱农牧交错地带沙漠化最严重的地区之一。科尔沁沙地沙漠化的发展,不仅导致了生态系统本身的破坏,给农牧业生产带来了严重危害。

This paper analyses the causes of the destruction of Korqin sandyland, indicating that adverse natural factors and unreasonable human productive activities play a decisive role in the destruction. For its restoration, the principles of developing beneficial and avoiding detrimental factors under local conditions must be persisted, and unreasonable productive ways must be ameliorated. Three types of empirical models for desert management are recommended.
