Abstract and Keywords

Abstract: Based on the investigation and statistics of typhoon-induced geological disasters in Anhui Province over the years, this paper analyzes the main characteristics of typhoon-induced geological disasters in Anhui Province, summarizes the distribution law of geographical space, elevation distribution law, stratigraphic lithology and structural distribution law of typhoon-induced geological disasters in Anhui Province, and summarizes the distribution law of relative position of typhoon paths. By comparing the occurrence time of geological disaster and typhoon, it is pointed out that the time of geological disaster induced by typhoon and typhoon action are basically the same, and there is no obvious lag phenomenon. The results can provide reference for geological hazard prevention and control in Anhui Province.

摘要和关键词

摘要: 文章基于对安徽省历年来台风诱发地质灾害的调查统计，分析台风在安徽省诱发地质灾害的主要特征，总结安徽省台风诱发地质灾害的地理空间分布规律、高程分布规律、地层岩性及构造分布规律，归纳台风路径相对位置的分布规律。对比分析地质灾害与台风的发生时间，指出台风诱发地质灾害与台风作用的时间基本一致，无明显的滞后现象。研究结果可为安徽省地质灾害防治工作提供参考。
