基于纳污控制的流域初始排污权配置模式研究

The model of basin initial emission rights allocation under the total emission control of water pollutants

面向纳污红线控制要求,结合我国流域纳污总量分解实践,以"纳污总量控制、兼顾公平和效益、尊重区域水环境容量差异、保障社会经济发展连续性"为配置原则,构建流域初始排污权多因素混合配置模式,并从配置模式的侧重点和功能角度,与现时经济活动量配置模式、非经济因子配置模式和排污绩效配置模式进行对比分析。以太湖流域为例研究结果表明:多因素混合配置模式集聚多种配置模式的优点,与水环境容量配置模式的配置方案比较接近,实现流域水环境纳污总量控制的有效分解,但适度提高了江苏省和上海市的COD、NH3—N和TP的初始排污权量,有利于促进经济的持续增长和社会公平。同时该配置模式操作简便,易于推广。

According to the red line of emission control of water pollutants, and the basin total emission quantity control allocation practice in China, this paper established a combined multi -factor allocation model for initial basin emission rights allocation in the principle of total emission control of water pollu- tants, the balance of fairness and benefits, respect for the difference of regional water environment, and guarantee of the continuous development of society and economic. From the perspective of the configura- tion modelg focus and function, a comparison analysis was made with the current economic activity allo- cation model, non - economic factor allocation model and the discharge performance allocation model. The research results taking Taihu Basin as an example showed that multiple hybrid allocation mode aggre- gated the advantages of the variety of configuration patterns, and it is closed to the water - environmental - capacity allocation mode, It has realized the effective decomposition of the total emission control of ba- sin water pollutants. At the same time, it is beneficial to promote economic growth and social justice with moderately increasing the amount of the initial emission permits of COD and NH3--N and TP in Jiangsu province and Shanghai city. Meanwhile, this allocation mode is convenient to operate and spread.
