摘    要:沙尘暴是一种强烈的风蚀输沙形式,是造成流沙蔓延和土地沙化最重要、最直接的作用过程之一。借鉴国际国内最新的研究进展,建立适合宁夏中北部地区气候特征的沙尘暴频率定量模拟模型,比较深入地分析宁夏中北部地区气候因素对沙尘暴频率的影响。

关 键 词:宁夏中北部地区  月沙尘暴频率  气候影响指数  模拟研究

Simulating the Effect of Climate on the Dust Storm Frequency in North and Medium Part of Ningxia.
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
