基于APDPC的流域水污染物减排机制研究

Stduy on discharge reduction mechanism of watershed water pollutants based on APDPC approach

针对我国现行的污染减排制度和减排方案与环境质量改善联系不紧密、激励约束机制不健全、减排责任落实不到位、监管与考核不力等问题,提出了基于人均累积(APDPC)的流域水污染物减排新机制,通过人均参考配额及人均累积参考配额,建立流域内不同区域间环境与经济的协调发展机制。以淮河流域为例,对安徽、河南、江苏和山东四省片区进行了实证分析,验证结果表明该方法具有公平、高效、简便、易操作等优点,具有较高的推广应用价值。

In the view angle that our country present pollution reduction system and the reduction scheme exist the following problems: not closely linked to the improvement of environmental quality,not sound for the incentive and constraint mechanism,not fulfilled the responsibilities of pollutants reduction and poor measures for supervision and assessment system,a new watershed pollutants emission reduction mechanism based on accumulative pollutants discharging per capita(APDPC) was proposed.The indices of pollutants discharge reference quota per capita and pollutants discharge accumulated reference quota per capita were applied to establish coordinative mechanism for environmental protection and economy development in watershed.Taking Huai River for an example,the regions of Anhui,Henan,Jiangsu and Shandong were analyzed,the case study results showed that APDPC approach has the advantages of simple operation,easy to test,not only cohesion with the current total quantity control system closely,also can balance the fairness and efficiency of total amounts of pollutants control,which have high values of generalization and application in the future.
