基于功效系数法的泥石流灾害预警研究
Research on early warning of debris flow based on efficacy coefficient method
摘要
Abstract
For great destructive debris flow, predicting the likelihood of its early warning is an important means of disaster prevention and mitigation, as well as scholars focus on the key issues. Based on the principle of efficacy coefficient method, analyzing the meteorological and geological environmental factors synthetically; evaluation factors such as hill slope, relative height, vegetation cover, along the groove loose material reserves, 5 d cumulative rainfall, maximum rainfall intensity per hour, and intraday rainfall are selected. Using the improved analytic hierarchy process to calculate the weight coefficients of evaluation factors, a early warning of debris flow prediction model is established. Taking an early warning of debris flow in Xiuyan for example, the model is tested to predict the results which reflect the actual situation better. The debris flow early warning model has higher reliability and practicability, and it can provide new ideas and methods for early warning of debris flow prediction.关键词
