中国城市节能评价的实证研究

首先,在评析我国现行节能考评指标局限性的基础上,界定了城市节能评价范围。其次,研究建立了包括工业、建筑业、城市交通、生活消费四个领域、三个层次、27个指标的城市节能评价指标体系,并构建了评价模型。第三,按照一定标准将城市用能水平划分为四个等级,并通过计算工业耗能指数A1和建筑、交通、生活综合耗能指数B,构建了城市耗能级别的判定准则Z=f(A1,B)。最后,以某城市为例进行了实证研究。研究结果表明:该城市2005年实际能耗位于第Ⅲ级,属于先进用能型城市;其中工业节能效果较好,建筑、交通、生活等其他三个领域节能有待加强。基本反映了该城市的能耗实际情况。

Demonstrable Research on China Urban Energy-conserving Evaluation

Firstly,based on analyzing the limitations of the current energy-conserving evaluation indexes,this article defines the urban energy-conserving scope.Secondly,the article has established urban energy-conserving evaluation model and evaluation index system.It contains 27 indexes in 3 layers with the basis of the industry,building,urban transportation and live consumption.Thirdly,according to the certain principles,it divides the urban energy-conserving level to four grades.Based on calculating industry energy consumption index A1 and synthesis index of building,transportation and live consumption B,it has set up the standing of energy-conserving level,that is.In the end,it takes some urban as an example to carry on a demonstrable research.The result proved the urban energy-conserving level was the Ⅲ class in 2005,belonging to advanced energy-conserving level.The industrial energy-saving result is better,but the job of energy-conserving about building,transportation and life consumption needs to be strengthened.The analysis result reflects the actual condition of the urban energy consumption basically.
