第一部分三门峡水利枢纽应该不应该修根除黄河水害和开发黄河水利主要有三个环节:上游开展水土保持,拦阻泥沙,下游进行河道整治,防止淤积,并在适当地点修筑调节洪峰及水量所需的水库。在这三个环节中,上游水土保持,下游河道治理,都需要较长时间才能生效。由于目前秦厂以下河道逐年淤淀,安全泄量有限,所以修建水库便成为目 The first part of Sanmenxia Hydro Complex should not be rooted in addition to the Yellow River water damage and the development of the Yellow River water conservancy have three main links: upstream water and soil conservation, blocking sediment, downstream river courses to prevent siltation, and in the appropriate site to adjust the flood peak and water required Reservoir. In these three aspects, upstream soil and water conservation, downstream river governance, take a long time to take effect. Due to the current Qin River plant sediment deposition following each year, the limited amount of safe discharge, so the reservoir will become the head
