摘要
地质灾害是地质作用引起的自然灾害。凡能够致灾的地质作用、地质现象或地质体,可统称“灾害地质因素”。我国海岸带地质环境脆弱且南北海岸带存在明显差异。随着沿海经济和社会快速发展以及全球变化的影响,地质灾害呈明显增强的趋势,其中人类活动也开始成为重要的影响地质环境的因素。总地来看,我国海岸带地质灾害因素多达8类51种,近年来地质灾害频繁发生,海岸带环境已经开始严重影响人类生存与经济发展。论文是在编制中国海岸带灾害地质图(1/200万)基础上撰写的。主要从类型及分布特点对我国海岸带灾害地质因素发育规律进行了总结。文章介绍了海岸带环境的地质背景、灾害地质因素类型与发育特征,并重点论述了以人工地质作用为主的灾害地质因素。
Geological disaster is one of the natural disasters caused by geological actions. These actions and geological bodies, as long as resulting in geological disaster, can be called geological hazard factors. The balance of China coastal geological environment is very weak and there are obvious differences between East China Coastal Zone and South China Coastal Zone. Following the rapid economic development and affected by the global environment change, the amount of happened geological disasters is increasing, At the same time, the artificial action is becoming a well known important coastal hazard factor. Generally speaking, there are 8 main classes and 51 types geological hazard factors found in China coastal zone, which are seriously impacting on the living quality and economic development potential. Based on the newly edited China Coastal Geological Hazard Map （1：2, 000, 000）, we give the summary on these geological hazard factors and their distributions. In this paper, we discussed the main coastal geological hazards, their geological background, classification, characteristics and special affections by artificial geological effects.
