摘　　要：【目的】随着都江堰灌区面积扩大与社会经济持续发展,岷江引水量逐年增加、城市供水挤占农业生态用水等问题突出。为解决以上问题,优化灌区水资源配置、切实保障粮食安全、落实水资源“四水四定”原则,开展了都江堰灌区初始水权分配的研究,建立模型,【方法】结合科学知识图谱分析说明社会对于水资源可持续利用的重要性,综合运用岷江生态下泄流量、GDP、各类用水量数据,通过社会敏感度计算可供水量,确定分配原则后利用水量分配多准则满意度模型为灌区各市分配水量,实现水量分配“两步法”。【结果】结果显示:2030年社会敏感度0.970,P=50%情况下鱼嘴可调水量98.52亿m^(3)。其中城镇居民生活用水,大部分地区两步法分配值与需水量相近;生态用水,两步法分配值均大于等于需水量;农业用水,眉山市两步法分配值低于需水量;工业用水,两步法分配值大于等于需水量。【结论】结果表明:利用社会敏感度推求可供水量,多准则满意度函数模型用于灌区水量分配的两步法既遵循社会发展规律与用水习惯,又尊重灌区内各城市发展差异,可为都江堰灌区水权分配提供一种思路。[Objective]With the expansion of Dujiangyan Irrigation Area and the sustainable development of social economy,the water diversion of Minjiang River is increasing year by year,and the problem of urban water supply squeezing agricultural ecological water is prominent.In order to solve the above problems,optimize the allocation of water resources in irrigation areas,ensure food security,and implement the principle of“water dominates development”for water resources,the initial water rights alloca-tion in Dujiangyan Irrigation Area was studied and a model was established.[Methods]The scientific knowledge map analysis is used to illustrate the importance of society to the sustainable utilization of water resources.The ecological discharge flow,GDP and various water consumption data of Minjiang River are comprehensively used to calculate the available water supply through social sensitivity.After determining the allocation principle,the multi-criteria satisfaction model of water allocation is used to allocate water for each city in the irrigation area,and the‘two-step method’of water allocation is realized.[Results]The result show that the social sensitivity in 2030 is 0.970,and the adjustable water volume of fish beak is 9.852 billion m^(3) under the con-dition of P=50%.Among them,the domestic water consumption of urban residents,the two-step distribution value and water demand in most areas are similar;for ecological water use,the two-step allocation value is greater than or equal to the water demand;agricultural water,in which the two-step distribution value of Meishan City is lower than the water demand;for industrial water,the two-step allocation value is greater than or equal to the water demand.[Conclusion]The result show that the two-step method of using social sensitivity to derive available water supply and multi-criteria satisfaction function model for water allo-cation in irrigation areas follows the law of social development and water use habits,and respects the development differences of cities in
