灰色关联分析在生态工业园清洁生产推进中的应用

清洁生产是生态工业园建设的前提,在现有改造型生态工业园的建设中必须逐步推进,并全面实行清洁生产。应用灰色关联分析方法对拟建生态工业园现有企业进行清洁生产评价,通过建立评价指标体系和评价标准,利用关联度和关联系数分别确定园区推行清洁生产的近期、中期、远期方案和找出制约企业提高清洁生产程度存在的问题。以龙门工业园焦化企业为例,研究结果表明,企业9和企业4的关联度>0.8,为园区优先推行清洁生产的试点企业,是园区清洁生产推进中的近期方案,分类指出园区下一步推行清洁生产的重点企业,为园区的中、远期方案。该方法原理简单,结果可靠,是一种有实用价值、适合于指导园区清洁生产推进的评价方法。

APPLICATION OF GRAY RELATIONAL ANALYSIS OF PROMOTING CLEAN PRODUCTION IN ECO-INDUSTRIAL PARK

Clean production is the precondition of construction of an eco-industrial park.Full realization of clean production must be promoted step by step in the exising reconstructive eco-industrial parks.The gray relational analysis method was applied in the assessment of promoting clean prouction in an existing reconstructive eco-industrial park.The indicator system and criterion of assessment were set up.The present, medium-term and long term schemes were respectively set down by the gray relational grade.At the same time, the main problems that restrain the improvement of clean production level of every enterprise were found out by gray relational coefficient.Taking coking enterprises in Longmen Industry Park for example, the results show that the gray relational grade of No.4 and No.9 enterprises exceed 0.8, in which experiments of carrying out clean production were made, that is to say,they are schemes of promoting clean production at present, and the enterprises are selected in the future,which is the scheme of higher cost for the park.The method is a very useful one for assessment of guiding clean production promotion in eco-industrial park with the advantages of uncomplicated principle and reliable results.
