中文摘要	浑善达克沙漠化防治生态功能区地处生态环境脆弱的东亚夏季风北缘,是我国北方生态屏障的重要组成部分,土壤风蚀是该地区面临的主要生态环境问题,决定了整个区域的生态安全程度。为更好地阐明浑善达克沙漠化防治生态功能区地区土壤侵蚀情况,利用RWEQ(Revised Wind Erosion Equation)模型定量分析了近10年来浑善达克沙漠化防治生态功能区土壤侵蚀强度时空变化特征,并通过地理信息再编码叠加分析技术剖析了强烈土壤风蚀区的主要影响因素。结果显示,研究期间研究区土壤风蚀强度特征空间分布变化变较大,受到植被覆盖度、气候条件、土壤特性、地形等因素共同影响,强烈侵蚀区域向西北地区移动,土壤侵蚀程度向恶劣化发展。
英文摘要	Desertification control ecologincal function area of Hunshandake is fragile and an important part of ecological barrier in north China,which is located in the northern margin of the east Asian summer monsoon region.Wind erosion is one of the major ecological environmental problems faced by the Hunshandake region,and determines the degree of regional ecological security.In order to better clarify the situation of soil erosion in the region,we quantitatively analyzed spatial and temporal variation characteristics of soil erosion intensity in the past decade in desertification control ecologincal function area of Hunshandake region by RWEQ (Revised Wind Erosion Equation)model and analyzed the main influence factors of strong wind erosion area by the recoding superposition analysis technology of geographic information.The results show that the different of spatial distribution of wind erosion intensity in desertification control ecologincal function area of Hunshandake during the study period is obvious,indicating that the strong erosion area moves northwest and the soil erosion degree becomes more serious,all of these are jointly influenced by various factors such as vegetation coverage,climate condition,soil characteristics and terrain.
