黄河干支流已建的大量水库、电站、引水工程以及大面积水土保持措施等,极大地改变了进入黄河下游河道的水沙条件,引起了黄河下游河道淤积萎缩。在新形势下,对河南黄河宽河段整治首要的任务还是确保黄河大堤和防洪安全,但其整治的重点应转向中水河槽,采取调水调沙和挖河疏浚等措施,保持河道主槽纵向输沙平衡和河势稳定;其次要充分考虑滩区群众的安全和发展需要,分区治理,引洪放淤,减缓二级悬河的发展;第三应建立利益协调机制,完善滩区政策,调整产业结构,充分利用黄河本身具有的各种资源,加快滩区群众致富步伐,建立和谐共赢的治河发展局面。
A large number of reservoirs, power stations, water diversion projects and large-scale water and soil conservation measures have been built in the tributaries of the Yellow River, which greatly changed the conditions of water and sediment entering the lower reaches of the Yellow River and caused siltation and sedimentation in the lower Yellow River. Under the new situation, the primary task of remediation of the wide reach of the Yellow River in Henan Province is to ensure the safety of the Yellow River embankment and flood control. However, the focus of its remediation should be shifted to the Zhongshui River flume. Water diversion and sediment dredging and dredging should be taken to maintain the main channel Secondly, we should fully consider the needs of the safety and development of the people in the floodplain areas, divide the floods and divert floods, and slow down the development of secondary suspended rivers. Third, we should establish a mechanism for coordinating interests and improving the policies on floodplain areas, Adjust the industrial structure, make full use of the Yellow River itself has a variety of resources to accelerate the pace of massacre of people in the floodplains, and establish a harmonious and win-win situation of river training.
