新情势下黄河口演变与整治研究思路

基于黄河口水沙变异的新情况以及经济发展和生态环境建设的新需求,提出新情势下黄河口演变与整治的研究思路。针对目前研究中需要突破的薄弱环节,瞄准国际河口学领域中的前沿问题,采用多学科交叉和多种研究手段,对黄河口开展创新研究。主要研究:黄河口水沙变异特征,尾闾河道枯萎机制及其演变响应,拦门沙演变响应过程及其反馈影响;河口泥沙通量,最大浑浊带、泥沙异重流形成机理,河口海岸淤进、蚀退及其动力平衡机制;黄河口陆海相互作用的整体数模,河口演变趋势与入海流路使用年限;新情势下黄河口治理对策及水土资源优化配置。

Study conception on fluvial processes and river regulation under the new environment of flow and sediment in the Yellow River Mouth

Based on the new condition of water and sediment and development of economy and ecological construction in the Yellow River Mouth, the study conception on fluvial processes and river regulation has been proposed. Aiming at the limitations of previous research, the interdisciplinary study and methods are adopted to develop a new study on the Yellow River Mouth. The main contents of the studies are as follows: the variational characteristics of water and sediment of the Yellow River Mouth, the mechanism of withering of the sink channel and its evolution reaction, the process of evolution response of the river_mouth bar and its effect, sediment flux, the turbidity maximum, the mechanism of the formation of density flow, coast silting forth and eating back as well as its mechanism of dynamic balance, an integral mathematical model of land and sea, the tendency of the River Mouth evolution and the lifetime of the sea flow path,and the strategy for the regulation of the River Mouth and the optimization of conservation under the new water and sediment conditions.
