我国沿海地区地质灾害现状及宏观防治对策

Current Situation of Geo-hazards and Macroscopic Preventive Measures in the Littoral in China

在我国人口密集、经济发达的沿海地区,地质灾害普遍发育,其造成的危害和损失不容轻视。地面沉降、水土流失、海水入侵等是沿海地区典型的地质灾害类型。根据不同地质灾害类型的分布情况,可将沿海地区地质灾害划分为华北沿海-长江下游和东南-华南沿海两个区域。应采取严格控制地下水开采量等有针对性的措施,对沿海地区不同地质灾害进行有效防治。

There are a lot of geo-hazards in densely-populated and economically-developed littoral in China. The damage they result in can not be despised. Ground-subsidence, soil-erosion and seawater-intrusion are typical geo-hazards in littoral. According to the distribution of different geo-hazards, we divide the coastal geo-hazards into two areas, respectively named the littoral of North China -lower reaches of Yangtze River and the littoral of Southeast-South China, where we should take appropriate countermeasures, such as strictly controlling the exploitation of groundwater to prevent and remedy different geohazards in littoral.
