中文摘要	土壤风蚀是浑善达克地区面临的重要生态环境问题,防风固沙功能大小决定了整个区域的生态安全程度.为了阐明浑善达克功能区防风固沙情况,指导区域的荒漠化防治,本文基于气象数据、遥感数据,利用修正风蚀方程模型(RWEQ)定量分析2000-2010年浑善达克防风固沙功能区防风固沙能力的时空变化格局,并通过主成分分析方法分析了功能区各县(旗)土壤风蚀的主要影响因素.结果表明:研究期间,浑善达克防风固沙能力随时间产生波动,总量呈下降趋势;单位面积防风固沙功能较强的地类有落叶针叶林和草原;功能区西部和东南部区域的防风固沙功能较弱,需要加强生态修复力度;对功能区内各行政区进行社会驱动力分析得出,土壤风蚀的3个主要社会驱动力分别为投入产出强度、经济发展水平和农牧业发展水平.
英文摘要	Soil erosion is an important ecological and environmental problem in Hunshandake Desert,and the sand-fixing function determines the degree of ecological security in the entire region. In order to clarify the situation of windbreak and sand fixation in Hunshandake area,and to guide the prevention and treatment of desertification on regional scale,based on the meteorological and remote sensing data,this paper quantitatively analyzed the temporal and spatial pattern of windbreak and sand fixation ability between 2000-2010 by the revised wind erosion equation (RWEQ) model,meanwhile,the driving forces for each county (or banner) in the functional zone were analyzed with the method of principal component analysis. The results showed that there was a fluctuation of the sand fixing capacity in Hunshandake over time,generally rendering a decline trend. The coniferous forest and grassland had strong windbreak and sand fixation capacity in unit area among the various land categories. In terms of spatial distribution,the windbreak and sand fixation function in western and southeastern region was weak and needed to be strengthened with ecological restoration efforts. Through the study of the social driving forces of each administrative region in the function zone,there were 3 main social driving forces of soil erosion in the administrative functions: the intensity of input-output,the level of economic development and the level of agriculture-husbandry development.
