摘要
青海省2018年汛期(6—9月)降雨异常偏多,全省平均降雨量为484.2mm,较常年同期偏多三成,列历史第1位,诱发了大量地质灾害,造成了较为严重的人员伤亡和财产损失。为提高对极端降雨条件下地质灾害发灾规律的认识,支撑地质灾害趋势预测研判,本文通过对比近10年来青海省地质灾害发灾规律,结合野外实地调查,以2018年为例,对青海省极端降雨条件下地质灾害的发育特征与分布规律进行了总结分析。
In the flood season of 2018(June to September),Qinghai Province experienced unusually high rainfall,with an average of 484.2mm,which is 30%more than the normal period and ranks first in history.This induced a large number of geological disasters,causing serious casualties and property losses.To improve the understanding of the disaster patterns of geological disasters under extreme rainfall conditions and support the prediction and judgment of disaster trends,this paper summarizes and analyzes the development characteristics and distribution patterns of geological disasters in Qinghai Province under extreme rainfall conditions in 2018,through a comparison of the disaster patterns in the past decade and field surveys.
