摘要
广西地处亚热带,气温高、雨量充沛,地质条件复杂,岩溶分布广,加上人类社会活动加剧,地质环境较为恶劣,导致地质灾害频繁发生。广西地质灾害具有活动频繁、分布广泛、群发性强、危害严重等特点。广西主要地质灾害有水土流失、膨胀土地质灾害、河岸崩塌、地面塌陷、水土污染、滑坡、泥石流、海水入侵、山区石漠化等。通过对广西壮族自治区环境地质灾害现状及危害进行了研究,分析了引发环境地质灾害的主要因素,并提出了切合实际的综合防治对策。
Located in the subtropical zone, Guangxi geological conditions, and wide Karst distribution. In has high temperature, plentiful rainfall, complicated addition, with the sharp increase of human＇s social activities in the area, the geological environment is relatively bad, and leads to the fact geological hazards results frequently takes place. The geological hazards in Guangxi have such characteristics as frequent activities, wide distribution, simultaneous occurrence, serious harms, etc. The main kinds of the geological disasters are water loss and soil erosion, expansive soil hazards, rivers bank collapse, ground subsidence, water and soil pollution, landslide, debris flow, seawater intrusion, rock desertification in rocky area, etc. The main factor triggering the environmental geological disasters have analyzed, based on detailed studies on the present situation and harm of the environment geological hazards in the Guangxi Zhuang Autonomous Region, and has put forward the corresponding practical preventive measures.
