煤炭资源型城市能源消费碳排放足迹变化与生态分析——以烟台市为例

Changes in Carbon Emission Footprint and Ecological Analysis of Energy Consumption in Coal Resource A Case Study of Yantai City

以典型煤炭资源型城市——烟台市为主要对象,利用生态足迹算法对该市2010~2019年主要能源消费碳排放的足迹变化、生态压力等进行分析。结果表明,研究时间范围内,烟台市的天然气消费量呈现持续上升的趋势,但煤炭依旧是烟台市最主要的能源消费方式;受煤炭消费总量的影响,烟台市的石油人均碳足迹呈现出升而后降的状态,但总体仍属于持续下降的趋势;整体自然生态环境所承受的负面影响力逐渐下降,生态压力年增长量不足0.3;受能源、经济结构优化发展的促进作用,烟台市整体碳排放足迹强度不断下降。本文结合实际分析结果,对烟台市未来能源结构、生态环保战略等提供一定建议。

Based on the typical coal resource-based city of Yantai,the ecological footprint algorithm was used to analyze the footprint changes and ecological pressures of carbon emissions from major energy consumption in the city from 2010 to 2019.The final analysis results indicate that within the research time frame,the natural gas consumption in the city has shown a continuous upward trend,but coal remains the main energy consumption mode in the city;Affected by the total coal consumption in the city,the per capita carbon footprint of petroleum in Yantai City shows an upward and downward trend,but overall it still shows a continuous downward trend;The negative impact on the overall natural ecological environment is gradually decreasing,and the annual increase in ecological pressure is less than 0.3;Driven by the optimization and development of the city's energy and economic structure,the overall carbon emission footprint intensity of Yantai City continues to decline;Based on the actual analysis results,provide certain suggestions for the future energy structure and ecological environmental protection strategy of Yantai City.
