烟台市能源消费碳排放足迹变化及动态分析

Change and Dynamic Analysis of Carbon Footprint of Energy Consumption in Yantai

以煤炭资源型城市烟台市为研究对象,采用生态足迹方法测算2005—2019年能源消费碳排放足迹,并进行生态压力和强度分析。结果表明,烟台市天然气消费量快速增加,煤炭仍是最主要的能源消费方式;总碳足迹变化受煤炭消费量影响,石油人均碳足迹先升后降,总体呈下降趋势,天然气人均碳足迹缓慢增加;生态环境承受力逐渐减弱,生态压力年均增长近0.3;能源结构改善和经济发展共同作用使碳排放足迹强度不断下降。根据研究结果,对继续优化烟台市能源结构、转变发展方式提出了针对性建议。

Taking Yantai,a coal resource-based city,as the research object,the ecological footprint method is used to calculate the carbon emission footprint of energy consumption from 2005 to 2019,and the ecological pressure and intensity are analyzed.The results show that the consumption of natural gas in Yantai is increasing rapidly,and coal is still the main mode of energy consumption;The change of total carbon footprint is affected by coal consumption.The per capita carbon footprint of oil increases first and then decreases,showing a downward trend,and the per capita carbon footprint of natural gas increases slowly;The bearing capacity of ecological environment is gradually weakened,and the average annual growth of ecological pressure is nearly 0.3;The improvement of energy structure and economic development work together to reduce the intensity of carbon footprint.According to the results,targeted suggestions are put forward to continue to optimize the energy structure and change the development mode of Yantai,in order to provide intellectual support for the realization of sustainable development.
