山洪灾害预警指标确定方法

简要分析了山洪灾害监测预警指标的类别和研究情况,在此基础上介绍了确定指标的理论和经验方法,主要的理论方法包括经典水文理论法、土壤饱和度—降雨量关系法、水位流量反推法以及暴雨临界曲线法,经验方法有统计归纳法、比拟法和内插法等,提出了加强山洪灾害预警指标研究的四点建议.

Determination of flood warning index for mountain flood

The type and research of monitoring and early-warning of mountain flood are briefed.Theory and experiences of indexes determination are introduced including methods of classical hydrological theory,saturation percentage of soil-precipitation relationship,back stepping method of water level and flow,as well as thunderstorm critical curve method and experimental methods of statistical deductive method,analogy method and interpolation method.Four suggestions are made for strengthening studies on early-warning of mountain flood disasters.
