Study on the Environmental Characteristics and the Mechanisms of Land Desertification in North Shanxi Province
摘要
Abstract
The northern Shanxi Province is located in the farming-pastoral ecotone in North China, the vulnerability and transitivity are its environmental features.Based on the field investigation on the vegetation degradation, soil thickness and wind erosion strength, this paper proposes the evaluation index of the extent of land desertification in northern Shanxi, and divides into the three levels, such as slight, moderate and severe.The cause mechanisms of land desertification are analyzed for Northern Shanxi, the results are as follows: the fragile natural condition is the basis, the irrational economic and social factors are the motive force,the irrational human activities are the essential factor in northern Shanxi province.关键词
