黄河水沙关系复杂,加之控导工程及生产堤的长期存在,加速了黄河下游“悬河”及“二级悬河”的发育,使得河滩地横比降增大,加剧了汛情危害,亟待治理。考虑到河道治理工程的特殊性,其水土保持措施在布设时应始终把黄河河道综合治理作为重要考虑因素,主体工程和水保措施的实施都要与治黄大局紧密结合。以“黄河下游东明阎潭—谢寨和范县邢庙—于庄‘二级悬河’近期治理工程”为例,探讨了“二级悬河”治理工程水土保持措施的布设要点,并提出了同类项目水土保持方案设计的建议,供后续治理工程及相关水土保持工作参考。
The complicated relationship between water and sediment in the Yellow River and the long-term existence of the control engineering and production dike accelerated the development of “suspended river” and “secondary suspended river” in the lower reaches of the Yellow River, resulting in an increase Flood damage, urgent treatment. Taking into account the particularity of river training projects, the comprehensive management of the Yellow River courses should always be taken as an important consideration when laying water and soil conservation measures. The implementation of main works and measures for water and soil conservation should be closely integrated with the overall governance of the Yellow River. Taking “Dongming Yan Tan-Xiezhai and Fanxian Xingmiao-Xiazhuang ’s Second-level Suspended River’ Recent Management Project ’in the Lower Yellow River as an example, the paper discusses the layout of soil and water conservation measures for the” Second Suspension River " Points out and put forward proposals for the design of soil and water conservation programs for similar projects for reference in follow-up management projects and related soil and water conservation work.
