摘要 洪水资源利用经济适度性是在满足生态适度性要求的前提下的经济合理性。利用构建的流域生态用水调度模型,提出了进行洪水资源利用经济适度性分析的方法,并在海河流域进行应用。对大型水库投资与供水效益的统计与模拟分析结果表明,受生态环境需水的约束,在水资源开发利用程度较高的流域通过工程措施来实现洪水资源利用边际效益越来越小。建议优先采用非工程措施来进行洪水资源利用,通过加强水资源管理、提高水资源利用效率和节约用水,缓解流域水资源危机。 Economic moderate criteria of floodwater utilization is a criteria of economic rationality under the presupposition that the ecological moderate criteria is satisfied. In this study, an approach to the economic moderate criteria of floodwater is proposed, and it was applied to the Hai River basin by using an ecological water operation model developed by the authors. According to analysis of the statistics and simulation results of investments and water supply benefits of the large reservoirs, the marginal benefit of their floodwater utilization by implementing engineering measures in the regions of water resources already exploited to a great extent, becomes increasingly lower recent years owing to the constraints related to ecological water demands. Thus, non-engineering measures should be considered for floodwater utilization to alleviate basin-scale water crisis. This could be achieved through various strategies of enhancing water resources management, improving water use efficiency, and saving water resources.
