antecedent precipitation index

The relationship between rainfall and debris flow occurrence and the impacts of antecedent precipitation on occurrence of debris flow and are discussed.

根据蒋家沟实测降雨资料,结合泥石流观测,分析泥石流形成的降雨组成和前期降雨对泥石流形成的影响。

A multidisciplinary approach based on logistic regression and antecedent effective rainfall was adopted to study the very complex phenomenon of rainfall-triggered debris flows.

利用Logistic回归模型对当日雨量和前期有效降雨量进行回归分析,形成了一整套对降雨型泥石流临界雨量进行定量分析的方法,并在辽宁省岫岩县进行了试用。

An approach based on logistic regression and antecedent effective rainfall is promoted.

将Logistic回归模型和前期有效降雨量引入到地质灾害预警领域,结合泥石流灾害危险性评价,形成了一整套较完善的泥石流灾害多元信息耦合预警体系,并基于MAPGIS平台经二次开发建立了泥石流灾害预警系统。

Research on the critical precipitation index of landslide based on GIS;

基于GIS的滑坡临界降雨指标的研究

This study is to determine the rainfall erosivity index used in China for plotting isoerodent map accurately by using detailed available weather station data.

降雨动能与最大 30min雨强的乘积EI30 是最常用的降雨侵蚀力指标 ,但计算复杂 ,且资料难以获得。
