Abstract

Using Qinhuangdao 1953-2017, 53 cases of geological disasters and disaster 3 to 7 days before the period of 24 h, occur daily rainfall data, analyzed the spatial and temporal distribution of geological disasters and rainfall, rainfall intensity, rainfall duration and the relationship between the geological disasters. The results show that Geological disasters induced by meteorological factors mainly include debris flow. The northern part of Qinhuangdao has more geological disasters than the south and mountainous areas, and the concentration occurred in July and August, especially in late July and early August.Short-term heavy rainfall with a daily precipitation of more than 50mm is the main meteorological influencing factor of geological disaster. Based on the geological disaster and rainfall relationship, disaster meteorological risk zoning is established, and the geological disaster rainfall model is established to provide scientific reference for government decision-making.
