基于双子系统协调耦合的流域初始水权配置模型

Initial Water Rights Allocation Model Based on Two Coupling Coordinative Subsystems

省区初始水权和流域级政府预留水量是流域初始水权的重要组成部分,研究省区初始水权配置子系统和政府预留水量配置子系统之间的耦合协调性是提高流域水资源利用效率的重要途径。面向最严格水资源管理制度要求,建立基于"三条红线"的耦合协调性判别准则,针对省区初始水权和流域级政府预留水量的配置方案,分别从水量、水质和用水效率视角判别两者之间的耦合协调性;针对未能通过耦合协调性判别的情形,提出调整两个子系统配置方案的方法,并重新进行判别,直至配置方案通过耦合协调性判别,从而获得流域初始水权配置推荐方案;最后,针对太湖流域进行实证研究。结果表明模型和算法具有可行性和有效性,可为其它流域开展同类研究提供借鉴。

Provincial initial water rights and basin-level government reserved water rights are indispensable parts of basin-level initial water rights. Research on the coupling coordination between the two sub-systems is an effective way to improve the efficiency of water resources usage. According to the requirements of Strictest Water Resources Management System（ in China）,the criterion of ＂Three Red Lines＂for coupled water allocation was established to judge the harmonity of the coupling coordination of the two sub-systems for the perspectives of water amount,water quality and water use efficiency. If the basin-level water allocation failed to satisfy the coupling harmonity of the two sub-systems,the individual allocation solution of the two sub-systems is adjusted until the coupling harmonious solution is reached and the solution of basin-level initial water rights allocation is obtained.The overall feasibility and effectiveness of the proposed model was demonstrated by the application to the case study of Taihu Basin in China. This study may provide important reference for similar research in other river basins.
