【摘要】 流域生态需水是指流域生态系统为维持一定程度的生态系统健康所需要一定质量的水量,以保证流域生态系统结构和生态功能等为目标,实现流域生态系统健康。流域生态需水量的研究对于社会经济的可持续发展具有重要的战略意义。论文针对南水北调西线一期工程的供水规划,在提出配水效益计算方法的基础上,针对不同的配水量,计算了黄河河口地区的生态需水量、生态效益以及供水对减少断流所带来的生态效益,并进行了方案比较分析。主要结论是:当来水量分别为55×108、122.8×108或240×108m3时,产生的湿地综合生态效益则为34.85×108、47.18×108或54.72×108元。

【Abstract】 Watershed ecological water demand is the water quantity that the watershed ecosystem needs to maintain the health of ecosystem and to guarantee the ecological structure and ecological function.The research about watershed ecological water demand is important for the sustainable economic and social development.In the paper,ecological water demand and ecological benefits are calculated,analyzed and compared,especially the ecological benefits reduced by decreasing dry-off.Also the three themes are compared and analyzed.The results can provide some reference for making water allotment of the first phase of western line project of south-to-north water transfer.It is concluded that the integrated ecological benefits of 34.85 hundred million yuan will be brought with incoming water of 55×108m3,the integrated ecological benefits of 47.18 hundred million yuan will be brought with incoming water of 122.8×108m3,the integrated ecological benefits of 54.72 hundred million yuan will be brought with incoming water of 240×108m3.
