基于碳源/汇角度的低碳城市评价指标体系构建

如何发展低碳经济和建设低碳城市已成为国际热点，而构建低碳城市评价指标体系则是低碳城市建设和发展的前提和基础。本文在对低碳城市理论和内涵详细分析的基础上，从城市碳源／汇角度出发，以定量评价城市能源利用和土地利用造成的碳排放为目标，构建了低碳城市评价指标体系。该指标体系包含了工业低碳指数、交通低碳指数、建筑低碳指数和土地碳汇指数4个二级指标及28个三级指标，并相应地设计了评价模型对各级指标进行综合。评价方法简单直观，并且可以根据城市能源消费结构的不同而调整权重，进而保证了评价不同类型城市时的公平性。

THE EVALUATION INDEX SYSTEM OF LOW-CARBON CITIES BASED ON CARBON SOURCE (CARBON SINK)

How to develop low-carbon economy and construct low-carbon cities has become an international hotspot, and building evaluation index system of low-carbon cities is the premise and basis of low-carbon city construction. Based on detailed analysis of the theory and connotation of low-carbon cities, this paper, from the angle of carbon source （carbon sink）, has built up an evaluation index system for low-carbon cities, aiming at quantitative appraisal of carbon emission caused by energy and land utilization in cities. This index system includes 28 three-level indexes and 4 secondary indexes, consisting of industrial low-carbon index, traffic low-carbon index, building low-carbon index and land carbon sink index, accordingly, an evaluation model is also designed to the composition of different levels of indexes. The method runs simply and intuitively. The weight of each index could be adjusted in the light of different structure of city energy consumption in order to assure the fair evaluation in different types of cities.
