基于治污成本法的流域生态补偿标准研究

目的]对河南省驻马店市小洪河流域生态补偿标准进行研究,为建立流域水质生态补偿标准核算模型提供参考。方法]通过搜集污水处理厂的运行和处理资料,选取COD、氨氮和总磷3个有代表性的污染因子,采用治污成本法和统计学方法开展研究。结果]西平县、上蔡县、平舆县、新蔡县的补偿值分别为0.40,0.46,0.58和0.88元/t,与相关研究结果较为相符。结论]基于治理成本模型的水质生态补偿标准核算模型能够很好地反映流域水污染因子的单位成本,为生态补偿机制的构建打下了坚实的基础。

Ecological Compensation Standard for River Basin Based on Method of Pollution Treatment Cost

Objective] The ecological compensation standard of Xiaohonghe River basin was studied in Zhumadian City to provide reference for establishing the account model of ecological compensation standard of river basin water quality.Methods] Based on the operation and handing data of sewage treatment plants, COD, ammonia nitrogen and total phosphorus were selected as the representative pollution factors, then pollution treatment cost method and other statistical methods were used to carry out the research.Results] The compensation values in Xiping County, Shangcai County, Pingyu County, Xincai County were 0.40, 0.46, 0.58, 0.88 yuan per ton, and the results were in good agreement with other related research.Conclusion] The water quality-based ecological compensation standard accounting model assessed by pollution treatment cost model can well reflect the unit cost of each water pollution factor of river basin, which laid a solid foundation for the construction of ecological compensation mechanism.
