Research On Evaluation System Of Low - Carbon City Based On Sustainable Development

At present, we are faced with city resources shortage, environmental pollution and ecological crisis. On the one hand, the sustainable development of the city can be promoted by the development of low-carbon economy. On the other hand, it would be better that we develop a low-carbon city based on the sustainable development.In this paper, low-carbon city comprehensive evaluation system is established in the perspective of sustainable development. The evaluation system of low-carbon city is divided into four subsystems, namely, economic development, social development, low-carbon development and sustainable development. This enriches the contents of the research on low-carbon city.Take Shanghai as an example. We collect the data of various indexes from2000to2012. The principal component scores and composite score for each subsystem are calculated by using principal component analysis method. And each subsystem development is analyzed. Through the analysis of the results, we found that from2000to2012in Shanghai city, economy and low-carbon development level is generally rising rapidly, the level of social development on the whole is stable, but the level of sustainable development has been in decline stage. The weight of each subsystem is determined by using entropy method. And in Shanghai city from2000to2012the score of each year low-carbon development level is calculated. According to the results we found that from2000to2012, the Shanghai comprehensive development level of low carbon has been substantially improved steadily.Finally, in this paper the policy suggestions are put forward from five aspects: the economic, social, energy, transportation and government, to raise the comprehensive development level of low-carbon in Shanghai. The results also provide reference for other cities to improve the comprehensive development level of low-carbon.
