内蒙古乌兰察布荒漠草原土壤风力侵蚀机理研究

水土流失已成为我国北方荒漠草原区经济社会可持续发展的主要问题之一。近年来,生态环境恶化,沙尘暴发生频率居高不下,受到国家和业内专家的一致重视。国内外专家们已对风蚀发生机制和影响因素作了许多研究,并取得了一定的成果。在前人研究基础上,选取位于内蒙古乌兰察布荒漠草原区的水利部水土保持生态野外试验基地作为典型研究区域,开展野外观测试验和野外移动式风洞模拟试验,定量研究影响风力侵蚀的有关因子,可为水土流失防治提供理论和技术依据。

Study on the Wind Erosion Mechanism of Wulanchabu Desert Grasslands in Inner Mongolia

In the north desert grasslands,soil and water loss has become one of main problems of the sustainable development of economy and society.In recent years,eco-environment deteriorates and sandstorm happens more frequently,which is highlighted for special attention by our nation and the specialists.Domestic and foreign specialists has studied on the mechanism and the influencing factors of wind erosion and yielded certain results.Based on the results of previous researches,the ecological field test base of soil and water conservation of Ministry of Water Resources on Wulanchabu desert grassland of Inner Mongolia was selected as typical research area to carry out the field test observation and field mobile wind tunnel simulation test,make quantitative research on relative influencing factors of wind erosion.This would provide necessary theory and ecology evidence for soil and water loss.
