发布时间：2019-07-30 08:45

【摘要】：系统梳理了20世纪中期以来国内外河流生态需水与生态调度的概念、方法、应用效果等,并针对黄河下游的现状对这些研究的适用性和应用前景做了述评。通过分析指出,黄河下游的生态需水与生态调度研究已取得了一定进展,既界定了总体量值范围,也考虑了不同水平年对应不同保证率下的流量过程。提出黄河下游生态需水与生态调度仍存在水文过程与生态系统作用关系尚未厘清、生态流量与水库调度尺度存在差异、黄河下游水库综合利用任务较难协调、未来水沙变化等因素具有不确定性等问题。
[Abstract]:This paper systematically combs the concepts, methods and application effects of river ecological water demand and ecological dispatching at home and abroad since the middle of the 20th century, and reviews the applicability and application prospect of these studies in the light of the present situation in the lower reaches of the Yellow River. Through the analysis, it is pointed out that some progress has been made in the study of ecological water demand and ecological dispatching in the lower reaches of the Yellow River, which not only defines the overall value range, but also takes into account the flow process corresponding to different guarantee rates in different levels and years. It is pointed out that there are still some problems in the ecological water demand and ecological operation in the lower reaches of the Yellow River, such as the relationship between hydrological process and ecosystem, the difference between ecological flow and reservoir operation scale, the difficulty of coordinating the task of comprehensive utilization of reservoirs in the lower reaches of the Yellow River, and the uncertainty of water and sediment changes in the future.
