基于灰色定权聚类的江苏省各市节能减排评价研究

Research on the Assessment of Cities' Energy Conservation and Emission Reduction in Jiangsu Province Based on Grey Fixed Weight Cluster

近年来,随着环境和能耗问题的日益严重,江苏省大力推进节能减排工作。通过采用灰色定权聚类评价分析模型,并将节能减排情况进行量化,对江苏省各个市2010年的节能减排成效进行评价。结果表明,南京、常州、无锡、苏州、泰州、徐州、淮安的成效较好,镇江、扬州、南通的成效较一般,而宿迁、盐城、连云港的成效相对较差。结合各项指标数据,对评价结果进行了具体分析,并对各市的节能减排工作提出了相应的改进意见。

In recent years, along with environmental and energy issues becoming increasingly serious, Jiangsu Province has vigorously promoted its energy conservation and emission reduction. By employing the analysis model of grey fixed weight cluster and quantifying the condition of energy conservation and emission reduction, this paper carries on the performance assessment of energy conversation and emission reduction of all the cities in Jiangsu Province in 2010. The result shows that notable achievements have been made by Nanjing, Changzhou, Wuxi, Suzhou, Taizhou, Xuzhou and Huaian, while Zhenjiang, Yangzhou and Nantong do a fairly good job, and at the bottom of the list are Suqian, Yaneheng and Li- anyungang. With the combination of each indicator, this paper also analyzes the causes of the results, and puts forward some relevant measures for the improvement of each city＇ s energy conversation and emission reduction work.
