Description :
In this paper, a quantitative research on the relationship between different underlying surface and sand-dust storm has been made by using 40 years meteorological data of 5 different types of underlying surface in northern China, which include farmland, grassland, sandland, gobi and salt crust. These data comprise sand-dust storm days and strong wind days. The AA. find that there are certain correlations between the days of sand-dust storm and strong wind for different underlying surfaces, which has great influence on sand-dust storm. There are pronounced differences in different types of underlying surface.
