Debris Flow Sensititvity Analysis on Land Use of the Upstream Watershed of Miyun Reservoir

doi:10.13466/j.cnki.lyzygl.2014.01.026

Abstract

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
