中文摘要：

针对我国最严格水资源管理制度要求,研究省区初始水权优化配置模型。首先,基于流域经济效益、省区排污权协调性等建立目标函数,根据流域排污总量构建约束条件,建立多目标省区初始排污权免费分配模型;其次,将排污权嵌入初始水量权配置中,根据奖优罚劣机制构建省区初始水权配置模型;最后,以太湖流域为研究背景进行实证研究。结果表明：太湖流域规划年2030年在75%来水频率下,基于流域可分配初始水权总量为363.3亿m^3和排污量为54.46亿m^3的限制,江苏、浙江和上海初始水权配置量分别为135.19亿m^3,129.21亿m^3和98.89亿m^3。本文的模型通过奖优罚劣函数,把超标或未超标排污的外部性内化到水量分配上,实现了水量权与排污权分配的统一,可为其它流域开展同类研究提供借鉴。

英文摘要：

According to the most stringent water resources management, provincial initial water rights allocation model was studied. Firstly, The objective functions including economic benefits of basin, optimal fairness and coordination of provinces were built. According to the constraint of the total pollutant discharge, a provincial initial pollutant discharge rights allocation model of multiple-objective is put forward. Secondly, based on the mechanism of rewarding excellence and punishing inferiority, a provincial initial water rights allocation model coupling with water quantity and water quality was built. Finally, the empirical research of Taihu Basin was adopted. The results showed that under water frequency of75%, the amount of initial allocation water rights is 363.3 billion cubic meters and the total pollutant discharge is 54.46 billion cubic meters in the planning year 2030. The initial water rights of Jiangsu Province, Zhejiang Province and Shanghai are 135.19 hundred million cubic meters, 129.21 hundred million cubic meters and 98.89 hundred million cubic meters, respectively. The allocation model internalized externalities of over-standard or under-standard pollutant discharge to the allocation of water quantity through the function of rewarding excellence and punishing inferiority. The model integrates provincial initial water rights and initial pollutant discharge rights. Furthermore, it provides an important reference for similar research in other basins.
