泥石流沟判别与危险度评价研究

以云南泥石流形环境的区域调查为基础，提出了以１１项因素作为泥石流沟判别与危险度评价预测的背景参数，依据关联性序列分析确定了因素的权重分析，应用数量化理论建立了泥石流沟判别模式和危险度评价预测的计算方法，实际应用结果表明该法可靠、简便和实用，适用蚶类泥石流沟判定与危险度的评价预测。

JUDGEMENT OF DEBRIS FLOW RAVINES AND EVALUATION OF RISK DEGREE OF DEBRIS FLOWS

Based on the regional survey on the environmcnt or debris flow formation in Yunnan Provincc, 11 factors are selected as the background parameters for judgement of debris flow ravines and evaluation of risk degree of debris flows. The weights of these factors are determined on the basis of the correlative sequence. Through the quantitative theory, the calculation methods or judgement of debris now ravines and prcdiction or debris flow risk degree are obtained. The results of application practices indicated that the methods are reliable, convenient and practical for judging debris now ravines and predicting the risk degree of debris flows, which can be applied to all possible and rainstorm induced debris flows.
