Study on Relation between Evolution and Its Stress Factors of Karst Rocky Desertification and its Stress Threshold Value Model--Taking Duan of Guangzi as the Ezample

摘要：

Stress threshold power law has provided new view angle and new method for rocky desertification. Taking Duan of Guangxi as the example, stress threshold power model of her rocky desertification evolution was established by the mathematics Curve Fitting. By way of analysis, stress threshold power announces the change law of rocky desertification Level. is occurred that unsuited reason of the mankind is intervened analysis object list the. therefore, control conforms to reason the mankind activity is the key effectively to provide prevention and cure rocky desertification.
