海岸带是社会经济最发达、人类活动最密集的地带,全球大部分经济财富均产生于海岸地区。就我国海岸带而言,沿海经济带仅占陆域国土的13.6%,却承载着全国41%以上的人口,创造出全国60%以上的国民经济产值。因此,海岸带地区经济能否健康持续发展在很大程度上决定了我国经济发展的大局。同时,由于海岸带处于海洋和陆地的交互地带,海陆相互作用强烈,地质环境极为脆弱,区内灾害类型复杂且破坏力极大。我国
Coastal zone is the most developed socio-economic zone with the most intensive human activities. Most of the world’s economic wealth is generated in the coastal areas. As far as our coastal zone is concerned, the coastal economic belt accounts for only 13.6% of the land area and territory, but it carries more than 41% of the country’s population and creates more than 60% of the country’s national economic output value.

At the same time, due to the interaction between the coastal zone and the land, the sea-land interaction is extremely strong and the geological environment is extremely vulnerable. The type of the disaster in the area is complex and destructive. My country
