【摘要】 根据川西红层地区的实际调查资料，应用模糊数学的理论和方法，建立起泥石流流域产沙分级评价模型。该模型能准确客观地反映流域内不同区域产沙的情况，并能自动编制流域产沙强度分级图，为流域内泥石流松散固体物质储量的计算提供依据。更多还原

【Abstract】 Based on western Sichuan′s red beds field suroey data and applying the theory and method of fuzzy mathematics,this paper presents an assessment model of sediment production Classification in debris flow valley. The model can accurately and objectively reflect the sediment preduction situation of different zones in the valley and automatl cally compile sediment preduction intesity coverage which will offer a sound basis for calculating the loose solids storage of the debris flow in the valley.更多还原
