摘要
基于水权交易进行湿地配水是湿地生态需水保障的制度创新。本文基于区间两阶段随机双层不确定性规划方法构建水权交易模型,定量分析自然湿地参与交易机制对大沽河流域水资源系统的效应。结果表明:自然湿地参与交易机制减少了河段环境容量,限制了行业排污量及实际用水量;此外,该机制下自然湿地通过买入水权满足其需水量成为水权主要买方,提高了市场活力,而社会生产用户间水权交易量降低,种植业是生产用户中最主要的水权出让方;该机制考虑自然湿地的生态效益,随着植被覆盖率的提高,系统效益随之增大;基于多判据分析,自然湿地参与交易机制下75%植被覆盖率情景表现最优。研究结果可为自然湿地作为市场主体参与水权交易提供理论基础,为生态、生产用水协同优化配置提供决策支持。
Wetland water allocation based on market mechanism is an institutional innovation for the insurance of ecological water demands.A water rights trading model was constructed based on interval two⁃stage stochastic bi⁃level uncertainty programming method.We quantitatively analyzed the effect of natural wetlands’participation on water resource system of Dagu River Basin.The results showed that the trading mechanism of natural wetlands par⁃ticipation reduces the environmental capacity of river sections and limits the amount of pollutant discharge and actu⁃al water consumption of industries.Under such mechanism,natural wetlands become the main buyer of water rights by purchasing water rights to meet their water demands,thereby enhancing market vitality.In contrast,the trading amount among social production users would decrease,and the planting industries would become the main seller of the social production users.This mechanism considers the ecological benefit of natural wetlands.The system benefit increases with increasing vegetation coverage.Based on the multi⁃criteria analysis,a vegetation coverage rate of 75%under the trading mechanism with natural wetlands participation has the best performance for water rights trading.Our results can provide a theoretical basis for natural wetlands to participate in water rights trading as main market players,providing a decision support for the coordinated optimal allocation of water resources in ecology and production use.
