Abstract

Abstract:

In this paper, the distribution, causes and characteristics of geological calamity in Lanzhou city were analyzed, and the temporal and spatial distribution of geological calamity and intense rainstorm, the weather systems and the relation between geological calamity and rainstorm intensity were studied mainly. The critical precipitation index were set up and defending countermeasure was given, and these will he necessary for developing prediction and warning of geological calamity in Lanzhou city.

Key words: Lanzhou city, geological calamity, rainstorm, intensity

摘要：

对兰州市区地质灾害的分布、成因、特点进行了分析，着重研究了兰州市区山洪灾害和强度暴雨的时空分布、产生强度暴雨的天气系统以及山洪灾害和暴雨强度之间的关系，确定了临界降雨量指标，提出了防治对策，这对我市开展地质灾害气象预报预警工作是十分必要的。
