Abstract:: Based on sand dust weathers and related meteorological data obtained from 9 meteorological stations in Chengde City from 1981 to 2010, analysis of the character and causes of sand-dust weathers (including dust, sand and dust storms) spatial distribution was performed and the corresponding prevention-control measures in Chengde area was put forward. The results showed that: spatial distribution character was that the occurring frequency of sand-dust weathers decreases along the Luanhe River Valley from northwest to southeast and the causes were the common action results of climate factors and underlying surface. Windy days had maximum correlation in the climatic factors on spacial distribution of sand dust weather in Chengde City and the surface topography and surface properties also had important effects on spatial distribution of the sand dust weathers. Only if humans make the reasonable land use structure, strengthen vegetation protection and reduce the population pressure on resources and environment, we can achieve the purpose of prevention of sand dust disasters.
