建设黄河口生态水利枢纽工程研究

为解决黄河人海水量减少给河口三角洲地区可持续发展带来的制约，许多专家提出过建设黄河口水利枢纽或生态枢纽的建议，据此完全可以合成一个生态水利枢纽综合工程方案：在原刁口河流路和现清水沟流路的分汊点西河口，通过合理的闸、坝、涵、库设计，建设生态水利枢纽的中枢工程；以清水沟流路和刁口河流路作为该枢纽的主动脉，配套建设黄河最下游的输水渠系；在枢纽终端的北、东两片咸淡水交汇海域建设生物多样性繁育区，从而可有效提高水资源的利用效益，形成维系海、河、陆生态平衡，促进河口地区可持续发展的新型治河工程。

Study on Building Ecological-Type Hydraulic Projects at the Yellow River Estuary

In order to solve the issue of restriction of sustainable development in the delta region caused by the reduction of the Yellow River water flowing into the sea, many experts once put forward a suggestion of building a hydro-junction or an ecological pivot in the Yellow River estuary. Hereby, it can combine the two into an integrated engineering plan of ecological hydro-junction, i.e. to build a central pivot project of ecological hydro-junction at the west river mouth of flow paths divarication of original Diaokouhe and existing Qingshuigou through reasonable design of gate, dam, culvert and reservoir; to take the flow paths of Diaokouhe and Qingshuigou as the main of the project and build a water delivery canal system at the most downstream forming as a complete set and, to establish a breeding zone of biodiversity at the confluence of salt and fresh water in the north and east of the project terminal for effectively increasing the utilization benefits of water resources, keeping the ecological balance of the sea, river and continent and promoting the sustainable development in the delta region.
