| Abstract: | Dust storm is a kind of serious wind erosion and one of the most important and direct processes of sand removal in arid and semi-arid regions. In the present paper, a quantitative model simulating the effect of climate on dust storm frequency was presented and the climatic effect on dust storm frequency in north and medium part of Ningxia was studied. Meteorological records of many years in five meteorological stations were applied to evaluate the climatic influential index and to simulate the actual dust storm frequency. |

| Keywords: | north and medium part of Ningxia dust storm frequency climate index index of soil moisture |
