为更加合理地在各受水区分配水源区水资源保护与提供清洁水源的成本,以及激发水源区对水资源保护的积极性,在对水源区和下游地区在水资源补偿中的行为和收益进行了博弈分析的基础上,建立政府与水市场调节相结合的水资源补偿模型,运用蚁群算法求模型最优解,给出水资源补偿方案.将此方案应用到西安市对太白县的水资源补偿,结果表明:太白县供给西安市水量为0.921×108 m3,能够得到约1.38×108元的经济补偿,西安市利用这部分水量增加收益约23.73×108元.方案能够实现水源区、受水区收益最优,同时达到区域水资源利用总收益最大化,为确定合理的水资源补偿标准提供参考.
In order to more rationally allocate water resources protection and provide clean water sources in the water catchment areas and stimulate the enthusiasm of the water source areas in protecting water resources, the behaviors and benefits of water resources compensation in the water source areas and downstream areas Based on the game analysis, this paper establishes the water resources compensation model which combines the government and the water market regulation, and uses the ant colony algorithm to find the optimal solution of the model and gives the water resources compensation plan.This scheme is applied to the water resources Compensation and the results showed that the water supply in Xi’an was 0.921 × 108 m3 in Taibai County and could get an economic compensation of about 1.38 × 108 Yuan and Xi’an City could increase the yield by about 23.73 × 108 Yuan by using this part of water. The district has the best income, and at the same time, it can achieve the maximization of the total income of the regional water resources utilization and provide a reference for determining the reasonable water resources compensation standard.
