一水土保持在治黄中应摆在什么地位?它是不是治黄的基础?大家一致认为:水土保持是治黄的基础,在洽黄的指导思想和全面计划中,必须放在重要的战略地位。(一)黄河下游危害的根本问题是泥沙太多。而下游的泥沙主要来自中游的水土流失。下游单是洪水大并不可怕,可怕的是泥沙太多,把下游河道淤成了“悬河”,而且每年升高10厘米,使下游防洪十分被动。同时,在干流上修大坝拦洪,也由于泥沙太
What is the place where soil and water conservation should be placed in treating the Yellow Sea? Is it the basis for treating the Yellow River? It is agreed by everyone that soil and water conservation is the foundation for treating the Yellow River and must be placed in an important strategic position in the guiding principle and comprehensive plan for the stabilization of the Yellow Sea. (I) The fundamental problem endangering the lower reaches of the Yellow River is that there is too much sediment. The downstream sediment mainly from the middle reaches of soil erosion. It is not terrible that the downstream flood alone is huge. The terrible thing is that there are so many silt that the downstream river silt becomes a “suspended river” and the annual increase of 10 centimeters makes the downstream flood control very passive. At the same time, dam repair floods in the mainstream, but also due to sediment too
