基于淮南市2002—2014年能源消费和植被覆盖等情况的基础数据,分析了淮南市碳足迹、碳承载力等相关表征指标的变化规律,以期为相关部门环境决策提供一些理论参考依据。结果表明:淮南市碳足迹稳中有增,量值较高,能源消费碳排放量较大,而碳承载力较小,特别是近几年,碳赤字严重;碳足迹强度持续降低,能源、资源利用效率随着科学技术的不断发展在不断提升,而碳压力指数仍然较高,区域生态压力较大;人均碳赤字和地均碳赤字保持在较高值;淮南市人均净碳足迹和净碳足迹密度均高于全省,而碳足迹强度和碳压力指数逐年接近全省并在近几年低于全省。总体来说,淮南市环境治理取得一定成效,但环境压力依然较大。
Taking Huainan as an example, according to the data of energy consumption and vegetation from 2002 to 2014, carbon footprint, carbon carrying capacity and other related characterization indexes were analyzed. The results showed that the carbon footprint of Huainan had been steadily increasing at a high value, which indicated energy consumption discharged vast quantities of the greenhouse gases; the carbon carrying capacity was quite small, especially in recent years, so the carbon deficit presents with severe situation; the intensity of carbon footprint had been decreasing that indicated a higher and higher efficiency in energy utilization with the continuous development of science and technology; the carbon pressure index was still high, as well as the per capita carbon deficit and the per area carbon deficit at a higher value ; the per capita net carbon footprint and the net carbon footprint density of Huainan were higher than Anhui, and the intensity of carbon footprint and carbon pressure index gradually was approaching and then was under Anhui in recent years. The environmental governance in Huainan made some achievements, but was still under large pressure.
