中文摘要:
      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m3,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m3,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m3。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。
英文摘要:
      To verify the rationality and universality of floodwater resources utilization pattern built in the part I of this paper, an application case is carried out in the Nansi Lake basin. First of all, the present situation and development potential of flood resources utilization is evaluated, according to hydrologic data during 1974-2008 years,annual average actual availability is 1.467 billion cubic meters,the present poten-tial and the theoretical potential are 288 million cubic meters and 733 million cubic meters,with the pres-ent utilization rate of 64.9%. Secondly, based on the elements of the flood control system, the choosing process for the floodwater resources utilization patterns is discussed,and then two potential development pat-terns, multiple duration flood limited water levels of the Erjiba Dam and floodwater distribution among riv-ers by sluice gates in the west region of the Nansi Lake, are taken as reasonable. The flood limited water level during the later flood season (from August 21 to September 30) can increase from 34.20 m to 34.35m, which the utilizable capacity of the Nansi Lake increases by 89.4 million cubic meters, and the peak level of the Nansi Lake increases gently by 0.02-0.026 m. The optimized scheme for floodwater distri-bution among rivers in the west region of the Nansi Lake is put forward, which can increase water storage 135.8 million cubic meters on the premise of without increasing the risk of flood control dramatically. The results above show the development pattern of flood water resources utilization in a basin scale is reason-able and feasible which include potential evaluation, development patterns choose and decision making by balancing the risks and benefits.
