摘　　要： 南水北调中线工程从丹江口水库调走部分水量,汉江中下游河道水量减少,水位降低,势必会改变汉江中下游干流供水区的水资源供需关系和生态环境条件,加剧该地区日趋严重的水资源供需矛盾,对该地区社会经济发展产生重要影响。在分析汉江中下游地区河道内生态用水、河道外社会用水的基础上,根据灰色系统理论,把灰关联度和灰关联熵结合起来,建立了基于灰关联熵的水资源分配模型,最终得到了该地区水资源利用的满意方案,对维持汉江中下游地区河道生态良性循环,保障社会经济的可持续发展提供了重要依据。 The middle route project which transfers some water from the Danjiangkou Reservoir will decrease the streamflow of the Danjiangkou Reservoir, change the water balance and environment condition of the middle and lower basins of the Hanjiang River. It has an obvious effect on the economic and social development. According to the research on environmental water demand and economic and social water demand, combined with the gray connectedness and entropy, a water resource allocation model based on the theory of gray system theory is developed, providing the system analysis of water resource with a new method. The method is applied to optimally allocate water resource in the middle and lower basins of the Hanjiang River, and its feasibility is discussed with the satisfaction result obtained.
