中国海岸穿过构造沉降带和隆起带,沉降带及隆起带断陷盆地的持续下降吸引了源远流长的大河在此人海,而隆起带内入海的河流多为近源小河,从而引起河流泥沙沿岸分配的不均和海岸沉积物的差异。沉降带内每公里海岸线接受的沉积物是隆起带的数十倍,且以砂质沉积物为主.隆起带河流泥沙来量少.而且砂质沉积物占了压倒的优势.河流泥沙沿岸分配的不均决定了中国沙质和淤泥质海岸的基本类型和分布格局、沉降带和隆起带松散沉积层的厚度和结构,山此产生了中国沿岸与第四纪沉积层有关的灾害和环境问题的有规律的分布。地面沉降主要分布于沉降带内,而地下海水入侵多出现在依赖地下水的隆起带内,底辟构造、浅层天然气往往在大河三角洲构成灾害和潜在的地质灾害.沉降带和隆起带断陷盆地内的海岸低地通常是海平面上升的主要脆弱地区.此外,丰富的河流泥沙使中国海岸对全球海平面上升的响应也不相同,如海岸湿地的再生和海岸侵蚀原因的复杂性等.
The continuous descent of the China coast through the tectonic subsidence zone and the uplift zone, the subsidence zone and the uplift zone faulted basin has attracted a great river with a long history and a long history. Most of the rivers entering the sea in the uplift zone are mostly near-sourced rivers, Uneven coastal distribution and differences in coastal sediments. Sediment belt per kilometer coastline to accept the sediment is uplifted several times, and mainly sandy sediments. Uplift with river sediment to less. And sandy sediments account for the overwhelming advantage. The uneven distribution of sediment along river sediments determines the basic types and distribution patterns of the sandy and muddy coasts in China, the thickness and structure of the loose sediments in the subsidence belt and uplift belt, and this has resulted in the connection between the Chinese coast and the Quaternary sediments Disaster and environmental issues regularly distributed. The ground subsidence mainly distributes in the subsidence zone. However, the underground sea water intrusion mainly appears in the uplift belt that depends on the groundwater. The diapir structure often causes the disasters and potential geological disasters in the Dahe delta. Subsidence Belts and Uplift Belt Coastal lowlands within the basin are usually the major vulnerable areas where sea level rise. In addition, the rich river sediment makes the response of the Chinese coast to global sea level rise differently, such as the complexity of the reasons for the regeneration of coastal wetlands and coastal erosion.
