基于能源消费的矿业城市二氧化碳排放多维度比较研究

实现矿业城市的绿色低碳发展是我国发展低碳经济所必须面临的问题,本文将我国75个典型矿业城市从生命周期和资源类型两个维度进行分类,利用2015年矿业城市能源二氧化碳排放数据、人口数据和经济数据(GDP)来对比不同矿业城市二氧化碳排放的差异,并运用数理统计方法来探索不同类型矿业城市二氧化碳排放与经济发展水平之间的关系。研究结果表明,二氧化碳排放高值城市和低值城市在空间上较为集中,且二者差距较大;成熟型的煤炭型城市二氧化碳排放普遍较高,成熟型的有色金属型城市或非金属矿型城市二氧化碳排放普遍较低;不同类型矿业城市分能源类型二氧化碳排放占比情况异中有同,并且在不同程度上满足二氧化碳排放与经济发展之间的正相关性。要实现矿业城市的低碳发展,应紧抓高碳排的矿业城市,稳定住低碳排矿业城市,加快矿业城市的经济转型,提高矿产资源开采、生产和利用效率。

Multidimensional comparison of carbon dioxide emissions based on energy consumption in mining cities

In the process of low-carbon development, carbon dioxide emission reduction in mining cities is one of the problems that must be faced. This paper classifies 75 mining cities from the perspective of life cycle and resource type, and compares the differences by using city energy consumption data, population data and economic data (GDP). After that, this paper explores the correlation between carbon dioxide emissions and economic development in different mining cities. The results show that the cities with high and low carbon dioxide emissions are spatially concentrated. Carbon dioxide emissions in mature coal-based cities are generally higher than mature non-ferrous/non-metallic metals cities and there is a big gap between them. In different mining cities, the proportion of carbon dioxide emissions in different energy types have both similarities and dissimilarities, and showing varying degrees of positive correlation between carbon dioxide emissions and economic development. To achieve low-carbon development in mining cities, the state should pay close attention to high-carbon mining cities, stabilize low-carbon mining cities, speed up the economic transformation and improve the efficiency of mining, production and utilization of mineral resources.
