黄河干、支流高含沙水流产生的因素

黄河是我国第二大河流,是中华民族的母亲河。但是目前已经成为地上"悬河",其主要原因是大量泥沙的淤积。而这部分泥沙主要来源于黄土高原区,特别是黄河中游的多沙粗沙区和粗泥沙集中来源区,通过高含沙水流的携带到达黄河下游,进一步淤积。本文主要阐述了高含沙水流的基本特点,分析了黄河干、支流高含沙水流产生的主要因素,提出了防治的基本措施,为黄河泥沙治理提供参考。

Factor for Producing of High - concentrated Sediment Flow in Branches in the Yellow River

The Yellow River is the second largest river in china and the mother river of the Chinese nation. But the Yellow River has become a "hanging river" now, because of the large number of sediment deposition. This part sediment comes from the Loess Plateau region mainly, in particular where sediment is come from in the middle Yellow River and is carries by high-concentrated sediment flow to the lower Yellow River and deposition. This paper expatiates the basic features of high-concentrated sediment flow mainly, analyses reasons of high-concentrated sediment flow in branches, puts forward the basic measures for control, provides reference for the management of the Yellow River sediment.
