摘　　要： 引江济汉工程作为南水北调中线水源区最重要的补水工程之一,主要任务是改善汉江兴隆梯级以下河道的农业灌溉、城市供水、航运和生态环境用水条件,使供水区的生态环境质量状况得到合理的修复,以期实现“南北互利”。引江济汉工程的渠道规模,是影响工程量、投资费用和工程效益的重要因素,科学合理确定引江济汉工程渠道规模,对实现南水北调中线受水区和水源区的经济、社会、生态环境协调发展具有重大意义。本文应用系统工程、渠道设计、工程经济学的理论和方法,建立了以供水量最大、生态环境需水量缺水量最小和工程规模利用率最大为目标、以水资源优化配置为基础的渠道规模多目标优选模型,首次提出了不同频率组合控制流量的多目标边际优选法,对引江济汉工程渠道规模进行了实例研究,取得了满意成果。 The Yangtze River diversion to the Hanjiang River, one of the most important compensatory projects in the water - head of the middle route of the south to north water transfers project, basically helps to improve water supply for agricultural irrigation, urban residents, river transportation, and the river ecosystem across the Xinglong rundle to benefit both the northern and southern parts. However, the scale of the canal impacts crucially the volume, investment and the profit. Therefore, a scientific and rational scale of the canal is significant. On basis of the optimal allocations of regional water resources, this paper proposes a theoretical account of systemic engineering, canal designing and the engineering economics of the model which has three objectives i. e., maximal water supply, minimal water deficiency for ecosystem and maximal efficiency for canal. In conclusion, with the marginal index methodology, by means of combining the different controlling flux, is hereby reported for the first time, the application of the optimal canal compensatory project, and with a satisfactory result.
