山西荒漠化类型与动态演变研究

＂荒漠化＂是指包括气候变异和人类活动在内的种种因素造成的干旱、半干旱和亚湿润干旱地区的土地退化。针对山西省荒漠化的动态变化,结合多年平均降水量、平均蒸发量、水蚀模数等因素,综合分析了山西省荒漠化动态变化的原因与现状。

Research on the Types and Dynamic Evolution of the Desertification in Shanxi Province

The desertification means the land degradation in arid,semi arid and dry sub-humid areas which is caused by various factors including climate variability and human activity. In the light of the dynamic variation of the desertification in Shanxi Province,and connecting with the mean annual precipitation,mean annual evaporation,water erosion module and other factors,this paper analyzes comprehensively the reasons and present situation of dynamic variation of the desertification in Shanxi Province.
