【摘要】：为验证本文上篇所建流域洪水资源利用模式的合理性与普适性,在南四湖流域开展实例分析。首先评价洪水资源利用现状与潜力,1974—2008年多年平均实际可利用量、现状利用潜力和理论利用潜力分别为14.67亿、2.88亿和7.33亿m~3,实际利用率为64.9%。然后针对防洪系统的组成要素,讨论二级坝汛限水位分期运用、湖西河系沟通调控等洪水资源利用方式的选择过程及其相应的实现途径。二级坝后汛期(8月21日—9月30日)汛限水位可从34.20 m抬高至34.35 m,增加兴利库容0.894亿m~3,湖泊高水位增幅0.020~0.026 m;提出的湖西河系沟通调控方案,可在几乎不增加防洪风险的前提下(1998年8月洪水),增加蓄水量1.358亿m~3。结果表明,集潜力评价、利用方式选择和风险效益综合评估于一体的流域洪水资源利用模式是合理、可行的。
[Abstract]:In order to verify the rationality and universality of the flood resource utilization model in the basin built in this paper, a case study was carried out in the Nansihu Basin. Firstly, the present situation and potential of flood resources utilization were evaluated. From 1974 to 2008, the average actual utilization capacity, current utilization potential and theoretical utilization potential were one billion four hundred and sixty-seven million, 288 million and 733 million mm3, respectively. The actual utilization ratio is 64.9. Then the application of flood limited water level of secondary dam by stages is discussed according to the elements of flood control system. The selection process of flood resources utilization mode and its corresponding ways of realizing. Flood season after secondary dam (August 21st-September 30th). The flood limit water level can be raised from 34.20 m to 34.35 m. The storage capacity of Xingli was increased by 89.4 million mm3, and the high water level of lake was increased by 0.020 ~ 0.026 m; The proposed communication control scheme for the river system in the west of the lake can be used without increasing flood control risk (flood volume increased by 135.8 million mm3 in August 1998). The results show that the assessment of gathering potential can be carried out. It is reasonable and feasible to select the utilization mode and evaluate the comprehensive risk and benefit in the watershed flood resources utilization model.

【正文快照】： 1研究背景中国水资源时空分布高度不均、与人类社会需求显著不匹配,这使得水资源开发利用就是通过兴建水利工程以及优化其调度方式等工程和非工程措施来提高水资源调控利用能力,从而尽可能多地将汛期洪水转化为常规水资源的过程[1-2]。从这一意义上讲,“洪水资源利用”或“洪
