Because of irrational structure and low benefits of windbreaks in northern Shanxi
the wind erosion quantity of the soil in severe section can reach as high as 120~135 m3/hm2.In order to provide a theoretical basis for design of windbreaks
based on an analysis of occurring rules of hazardous wind
characteristics of sandstorms and mechanical structure of topsoil in northern Shanxi
a research on key factors for design of windbreaks had been done by establishing mathematical models.The results are as following:...
