河口地处河流与海洋的交比地带,动力环境复杂、冲淤变化激烈;河口是海陆交通的咽喉地区,在国民经济发展中居于重要的位置。随着我国沿海外向型经济开发区的建立,对外贸易的剧增,河口自然资源的开发利用,河口的研究在国民建设中具有明显的社会效益和经济效益。河口研究的核心问题是河口沉积动力过程的研究,只有搞清河口沉积动力过程,才能从机制上解释河口环境的发育历史,才能预测其发育演变趋势,为河口治理提供依据。
The mouth of the estuary is located at the intersection of rivers and oceans, with complex dynamic environment and fierce erosion and deposition. The estuary is the throat area of land and sea transportation and occupies an important position in the national economic development. With the establishment of China’s coastal export-oriented economic development zone, the sharp increase of foreign trade and the exploitation and utilization of estuarine natural resources, estuary research has obvious social and economic benefits in the national construction. The key issue of estuary research is the study of the dynamics of estuary sediment deposition. Only by studying the dynamic process of estuary deposition, can we explain the developmental history of estuarine mechanism from the mechanism and predict its development and evolution trend, which can provide the basis for estuary governance.
