| 摘 要： | 利用宁夏中北部地区6个气象站多年气象资料，分析了月平均风速、土壤湿润度、地面温度及下垫面风蚀沙化系数对沙尘暴频率的影响，计算了各气候因素对本地沙尘暴频率的影响指数，建立了适合宁夏中北部地区的沙尘暴频率的定量模型，并利用气候影响指数对沙尘暴频率进行拟合，取得了比较理想的效果。

| Abstract: | Using the milt-year meteorological data at six representative stations in the mid-and north-parts of Ningxia, the effects of the monthly mean wind velocity, soil moisture and coefficient of wind erosion and desertification in underlying surface on sand storm frequencies are analyzed. The effect indexes of the climatic factors on sand storm frequencies are calculated. Also the regression equation suitable for fitting sand storm frequencies in the mid-and north-parts of Ningxia have been finished. |
