摘要: 北京山区泥石流较为发育。泥石流活动与区域特殊的自然条件和人类活动密切相关。选择北京密云水库上游集水区为研究区,在RS和GIS技术支持下,定量分析研究区内土地利用方式对泥石流的敏感性。研究发现:易导致泥石流灾害发生的土地利用方式依次为8~15°的疏林地、<8°的其他建设用地、15~25°的疏林地和中覆盖度草地。研究成果对于指导土地利用方式、布局水土保持工程及减少泥石流危害等具有一定的参考意义。

Abstract: Debris flows in Beijing mountains area are well developed.Debris flow activities are closely related with the area of the special natural conditions and human activities.With Beijing Miyun reservoir upstream watershed as an example,under the support of RS and GIS,the sensitivity of different kinds of land use on debris flows was systematically calculated.On the basis of integrated analysis,the most vulnerable land use types to debris flow disaster are open forest land at the slope of 8 degree to 15 degree,construction land at the slope of less than 8 degree,sparse grass coverage and medium coverage grass land at the slope of 15 degree to 25 degree.Research results could be used to guide the land use type and the layout of soil and water conservation engineering and so on with certain reference significance.

Key words: land use, debris flow, sensitivity, Miyun reservoir, RS, GIS
