中文摘要：

面向最严格水资源管理制度的约束，省区初始水权配置过程必须考虑水质对水量配置的叠加耦合制约，同时也要考虑用水效率对水量和水质的影响。本文以政府强互惠（GSR）理论为基础。借鉴二维初始水权配置理念，基于耦合的视角，结合区间数理论，利用强互惠者政府方在省区初始水权配置系统中的特殊地位和作用，通过“奖优罚劣”的强互惠措施设计，将水质影响叠加耦合到水量配置，构建基于GsR理论的省区初始水权量质耦合配置模型。以太湖流域为例进行案例分析，获得不同约束情景和减排情形下的2020年太湖流域9种省区初始水权量质耦合配置方案，研究结果表明：①在相同用水效率约束情景下，在受到减排情形h=l，2，3的影响时，江苏省和上海市的初始水权配置区间量随着减排责任的减少而增加，浙江省的配置区间量随着减排责任的减少而减少；②与仅考虑水量或用水效率约束的省区初始水量权的配置结果相比，将水质耦合到水量配置的影响是江苏省和上海市的初始水权配置区间量的折减，浙江省配置区间量的增加，以奖励浙江省的减排行为，同时，分情景分情形以区间数的形式给出省区初始水权量质耦合配置结果，更适应最严格水资源管理制度的要求。

英文摘要：

In accordance with constraints of the strictest water resource management system, the initial water rights allocation among Chinese provinces must embed water quality effects into the process of water allocation. The processes of water allocation also needs to take the effect of water- use efficiency to water quantity and quality into consideration. Combining with interval number theory, governmental strong reciprocator theory and initial two-dimensional water rights allocation theory from the coupling perspective, we designed a strong reciprocator system based on the principle of ＇rewarding efficiency and penalizing inefficiency＇ using the special position and role of the governmental strong reciprocator. As a result of the strong reciprocator system, we propose a water quantity-quality coupled model for the provincial initial water rights allocation by embedding water quality effects into the processes of water allocation. The model of provincial initial water rights allocation is applied to Taihu Basin, to get its nine schemes of the provincial initial water rights allocation in 2020 constrained by different water-use efficiency and emission patterns. At the same standards of water-use efficiency, the amount of initial water rights allocation interval in Jiangsu Province and Shanghai City increases with decreasing water emission responsibility; the amount of Zhejiang Province is otherwise. These results, compared with allocation schemes that merely consider water quantity and water-use efficiency, show that the interval quantity from Jiangsu Province and Shanghai City should be reduced, while the interval quantity from Zhejiang Province should be increased as an incentive for the reduction in water pollutants. Water quantity-quality coupled schemes of provincial initial water rights allocation manifested by interval in multiple scenarios are according with the requirement, which is constrained by the strictest water resource management system.
