摘要: 地质灾害的诱发因素包括自然因素和人为因素.人为因素主要与人类工程活动有关.在一定的地质地形条件下,自然诱发因素则主要是降雨.因此在确定的地质环境背景下,研究气象和地质灾害发生的耦合关系极其重要.本文通过总结前人关于地质灾害预报预警的研究,提出了一套完整的应用降雨对地质灾害进行预报预警的方法体系.

Abstract: Two kinds of triggering factors are currently considered in prediction or forecast of geo-hazards:natural and man-made. Under given geological and geomorphic conditions, rainfall presents a key natural factor. Therefore it is important to study the coupling relation between the occurrences of geo-hazards and weather under certain geological background. After thereview of previous research on early warning of geo-hazards, the paper works out a suit of method to early warn geo-hazards based on weather forecast.
