中国主要城市低碳化发展指数的测度与分析

处于快速城市化、工业化和机动化过程中的中国城市,向低碳化发展是其必由之路。基于DPSIR模型,从低碳化基础、能源低碳化、产业低碳化、建筑低碳化、交通低碳化、环境低碳化、碳汇能力和社会低碳化8个方面构建城市低碳化发展指数的评价指标体系,以线性加权法对我国36个城市进行了测度。结果分析表明:城市总体低碳化发展水平不高,还没真正意义上的低碳城市,将之划分为3个准低碳城市、22个中碳城市、11个高碳城市;低碳化发展指数整体上呈现出由东向西、由南到北逐渐减小的分异态势;低碳化发展指数与城市财富和城市规模都没有明显的相关关系;低碳化发展在各个方面还不平衡,薄弱之处需要提高。该研究试图为各市统筹兼顾、因地制宜地实现低碳发展提供科学基础。

The Measurement and Analysis on Index of Low Carbon Oriented Development for Major Cities of China

In the process of rapid urbanization,industrialization and motorization in Chinese cities,low-carbon oriented development is the only way.Based on the DPSIR model,the paper built firstly the evaluation indicator system of urban low-carbon oriented development index(LCDI) from the aspects of low-carbon oriented base,low-carbon oriented energy,low-carbon oriented industry,low-carbon oriented architecture,low-carbon oriented traffic,low-carbon oriented environment,capacity of carbon sink and low-carbon oriented society.Then it measured the LCDI of 36 cities in China with a linear weighting method.The analyzing results indicates that: all the levels of low-carbon oriented development was not high and there wasn′t a real low carbon city in China;These 36 cities is divided into 3 quasi low carbon cities,22 middle carbon cites and 11 high carbon cities;The space distribution of LCDI reduced gradually from east to west and south in China;LCDI had no obvious related correlation with city wealth and city scale;Each aspect of low-carbon oriented development also didn’t balance,the weak of department deeded in need of improving.This research attempted to provide a scientific basis for how to plan and construct low carbon cities with Chinese characters.
