本文通过对黄河泥沙的来源、多沙史实、产沙自然环境与地质背景的剖析,论述了黄河发展成为地上悬河的必然归宿。因此,在制定河防战略对策时,应当在上、中、下游采取综合措施,全面规划治理,才有可能确保下游防洪安全。尤其对下游地质隐患的防治,灾害性地震对河防工程的破坏,以及下游河道寿命三个重大问题,需要加强研究。
Based on the analysis of the source of the sediment in the Yellow River, the historical records of sand, the natural environment and the geological background of sediment production, this paper discusses the inevitable return of the development of the Yellow River into a hanging river. Therefore, when formulating the strategy of river defense strategy, comprehensive measures should be taken in the upper, middle and lower reaches to comprehensively plan and control so as to ensure the safety of downstream flood control. In particular, prevention and control of geological hazards in the lower reaches, destruction of riverine defense projects by disastrous earthquakes and three major issues concerning the life of downstream rivers need to be strengthened.
