| 摘 要： | 河口海岸是地球四大圈层交汇、能量流和物质流的重要聚散地带。该区域经济发达、人口集中、开发程度高，导致严重的环境变异、资源破坏，对区域持续发展造成重大影响，特别是我国流域高强度开发河口和邻近海岸带有直接和深远的影响。新世纪我国的河口海岸面临着4个方面的挑战：入海泥沙量急剧减少；入海污染物质显著增加；滨海湿地丧失；全球海平面上升对中国低海岸的严重威胁。为此，开展河口海岸环境变异的研究，为解决国家目标和海岸带资源可持续利用，无疑是非常重要而迫切的问题。

| Abstract: | Estuaries and coastal zone are the intersection of four spheres:atmosphere,lithosphere,hydrosphere and biosphere,an important convergence/divergence zone of matter and energy,where developed economy,dense population and highly intensive exploitation induce adverse environmental changes and serious resource destruction,which have great impacts on coastal sustainable development,especially the highly intensive development in river basins has direct and pronounced effects on estuaries and their adjacent coasts.In the new century,China estuaries and coasts are faced with four main challenges:sharp decrease of sediment discharge into sea,rapid increase of pollution matter into sea,loss of coastal wetland and the impacts of global sea level rise on the coastal lowland of China.Therefore,it is undoubtedly very important and urgent to carry out studies on estuarine and coastal environmental changes,in order to solve national goals and sustainably utilize coastal zone resource. |
