生态工业园污染减排绩效回顾性评价指标体系的构建与应用

Retrospective evaluation of pollution emission reduction performance of a Chinese eco-industrial park

为挖掘生态工业园建设过程中污染减排的途径和动力，评价其减排绩效和年际变化规律，彰显生态工业园建设的优势和特色，构建了以熵权法确定权重、多目标决策综合评价模型为基础的生态工业园污染减排绩效回顾性评价指标体系与方法，并应用于日照经济技术开发区生态工业示范园区。结果表明，2003~2012年间：（1）日照经济技术开发区的主要污染物排放呈先增、后减、再增的现象，减排绩效与生态工业园创建阶段呈现明显相关关系，污染减排绩效呈明显的阶段性特征；（2）经济发展与污染物排放呈“绝对脱钩”现象，工业增加值提高了10.6倍，而COD、氨氮及SO2的排放量则分别削减了54.2％、28.4％与81％；（3）减排绩效体现出明显的生态工业园特征，清洁生产、产业共生以及基础设施共享是污染物持久减排的主要途径；（4）与全国工业减排绩效相比，日照经济技术开发区在工业增加值增长速度以及污染物排放总量与强度控制方面具有明显的优势。

To identify the means and driving force for pollution control,and assess the performance,the pros and fea-tures of Eco-industrial Park（ EIP）construction,a new index system is established to evaluate the retrospective effects of the emission control performance of an EIP,and is applied successfully in a case study of Rizhao Economy Technology Development Zone EIP（RZEIP）. Results show that during the ten-year span from 2003 to 2012,（1）the performance of the emission control in Rizhao EIP shows a feature of obvious different phases following the pattern of increasing, reducing and increasing;（2）throughout the construction and development,the economic development is found to have a“relative decoupling”relationship with the total emission of the pollutants. The industrial added value was increased by 10. 6 times,while the emissions of COD,ammonia and SO2 were reduced by 54. 2%,28. 4% and 81%,respective-ly;（3）the performance reflects the typical characteristics of EIP and cleaner production,industrial symbiosis and infra-structure sharing are the main way of sustainable emission reduction;（4）compared to the national level,RZEIP repre-sents faster economic growth,better total emission and intensity control.
