如何衡量污染物控制的经济成本,以期给出落实水质达标红线的最小经济成本,成为迫切需要解答的现实问题。目前已有研究中定量分析工具较少,且存在不足。该文在讨论经济增加值与污染物排放相关研究的基础上,推导出地区工农业经济增加值—污染物排放量函数,用于定量分析流域的经济产出与入河污染物排放量。以陕西省渭河流域作为实例分析表明:该函数精度较好,可为流域管理提供定量分析。 How to measure the economic cost of pollutant control so as to give the minimum economic cost of implementing the red line of water quality becomes a realistic problem that needs urgent solution. At present, there are few quantitative analysis tools in the research and there are some shortcomings. Based on the research on economic added value and pollutant emission, this paper deduces the value added of industrial and agricultural economy - the pollutant discharge function, which is used to quantitatively analyze the economic output and pollutant discharge into the river basin. The case study of Weihe River Basin in Shaanxi Province shows that the function has good accuracy and can provide quantitative analysis for watershed management.
