摘要
从防灾观点出发,从河道的水动力学特性入手,研究决定黄河下游河道水动力学特性的因素,找到河道水动力学特性和影响因子之间的关系。在此基础上,从水流运动和泥沙输移之间的关系出发,分析黄河下游河道的泥沙运动特性,对于黄河下游河道的演化特性作了探讨,对于治理黄河提出了建议。和黄河下游河道紧密联系的下游滩区问题,不仅仅是一个自然科学的问题,而且是和社会、经济、环境、资源等问题相关的一个综合性问题,本文从可持续发展的角度出发,给出了解决滩区问题的建议。
Yellow River is very much important to China, but it has long faced alot of problems. From the viewpoint of disaster prevention and reduction ,the hydrodynamic properties of Lower Yellow River Channel were studied. The hydrodynamic factors to influence the Lower Yellow River Channel were investigated to find their relations. Sediment movements of Lower Yellow River Channel were explored on the basis of relation between fluid flow and sediment transportation to predict evolutional process of Lower Yellow River Channel to give suggestion for permanently harnessing Lower Yellow River. The problem of beach area of Lower Yellow River is a comprehensive balance among society, economy, environment and natural resources rather than an only physical problem, and suggestions were proposed to solve this problem from the view of sustainable development. This paper also finds that it is necessary to deal with Yellow River together with Huaihe River.
