永定河流域生态补偿标准研究

Research on the ecological compensation standard of Yongding River Basin

考虑过去流域生态补偿研究中具有忽略水质功效、生态价值计算方法缺少系统性的不足,本文总结出基于水量水质模拟、水生态价值核算的流域生态补偿标准测算框架,并以水量水质功效的不可分割性为基础,得到了永定河跨界断面补偿标准。借鉴永定河流域生境及物种的多元化、不同水域相关功能属性的差异性,从河流生态系统、森林生态系统、湿地生态系统层面考虑,借助投入产出对应关系确定受益补偿标准为150亿元。以限制发展机会成本、水源涵养损失机会成本为依据,得到流域生态受损补偿标准为16亿元。最后结合应用成果,探讨了生态补偿标准完善策略。

The studies of watershed eco-compensation schemes which emphasize water quality efficiency and systematic ecological services value calculation methods remain less. The paper presents watershed eco-compensation standard calculation framework based on water quantity-quality simulation and water eco- system services value. Considering water quantity and water quality integrity, the paper supplies Yongding River Basin ecological compensation standard across hydrological control sectors. The author gives Yongding River Basin benefit compensation standard by considering ecosystem species and habitats diversity, water body function differentiation from river, forest and wetland system. The benefit compensation value is annu- al 15 billion yuan in terms of input-output relationship. The damaged compensation standard is annual 1.6 billion yuan by taking into account the opportunity cost of limiting development and water conservation loss. Finally, the paper illustrates the perfection suggestion of eco-compensation standard based on practice result.
