中文摘要：

中国北方大多数地区遭受着严重的风力侵蚀,风力侵蚀可导致土壤中有机物流失、土壤肥力下降,最终会导致土地荒漠化。中国北方地区风力侵蚀问题日益突出,由此带来的扬沙天气、沙尘暴等灾害天气增多,给人们的生产生活带来许多的不利,并且严重影响人们的身体健康。从影响风蚀区地表景观的风力方面出发,利用全国209个气象站2001~2011年全年的某一风速等级累计时数,借助GIS技术,生成中国北方风蚀区地表大于5 m/s的风速年累计时数空间分布图和冬春季节累计时数空间分布图,研究中国北方风蚀区风力侵蚀因子参数特征。同时,在分析扬沙风速年累计时数空间分布及时间变化基础上探讨与风蚀景观空间分布和时间变化关系,提出防治风蚀区风力侵蚀的措施。这一研究对于北方风蚀区防治沙尘暴等灾害天气,防灾减灾、减少灾害带来的损失,具有重要的意义。

英文摘要：

Most areas in northern China suffered serious wind erosion. Wind erosion can lead to soil erosion and fertility decline, and ultimately lead to desertification. Wind erosion problem is increasingly prominent in northern China; as a result the number of sand- storm disasters such as the weather is increasing, and bringing so much trouble to people~ production and living. From the wind ero- sion region, wind erosion wind effects, using of 209 weather stations across the country in 2001 to t2011, a wind speed data accumula- ted hours per month, with GIS to generate wind erosion area spatial distribution of surface wind speed data in north China. To research wind erosion area in north China wind erosion factor parameter characteristics. Meanwhile, on the analysis of the spatial distribution of wind speed and wind erosion and landscape change and spatial relationship are discussed on the basis of the measures to reduce soil wind erosion. The research for the north wind erosion area disaster prevention and reduction, to reduce disaster losses, has the vital significance.
