长江沿岸28个城市的低碳化发展评价

长江沿岸上、中、下游28个地级以上城市可视为我国东、中、西部城市的缩影,因此,沿江城市的低碳化发展水平客观上反映着中国低碳城市整体发育程度与区域差异。在分析、理解低碳城市内涵的基础上,构建低碳城市评价指标体系,提出低碳指数概念,并从时空路径对长江沿岸28个城市的低碳指数进行聚类分析与评价。认为我国低碳城市建设应该以不影响社会经济快速发展为根本前提,低碳城市发展应该以平均相对量指标作为评价标准;不同城市可根据构成低碳指数的3个分项指标的具体情况,制定相对应的低碳城市发展战略,提高城市综合低碳指数。

Appraisal of Low-carbon Development to 28 Cities along the Yangtze River

The 28 cities at or above the prefectural level in the upper,middle and lower reaches of the Yangtze River can be regarded as an epitome of the cities in eastern,central and western China.Therefore,the low-carbon development level of the cities along the Yangtze River objectively reflects the overall development degree and regional difference of Chinese low-carbon cities.On the basis of analyzing and understanding the connotation of low-carbon cities,this thesis sets up the appraisal index system of low-carbon cities,puts forward the concept of low-carbon index,and conducts a cluster analysis and appraisal to the low-carbon indexes of 28 cities along the Yangtze River through a spatio-temporal path.The construction of Chinese low-carbon cities should not affect the rapid social and economic development first of all;the development of low-carbon cities should be appraised according to the index of average relative volume.Different cities can work out corresponding development strategies of low-carbon cities according to the specific circumstances of 3 sub-indexes that constitute low-carbon index,so as to enhance the comprehensive low-carbon index of cities.
