随着《京都议定书》的签订,减少CO2等温室气体的排放和减缓全球气候变暖趋势已成为世界各国关注的焦点。煤矿作为中国煤的主要来源,是最大的碳源。煤矿企业通过植树造林,一方面可以修复受损的矿区环境,另一方面可以通过森林巨大的碳汇功能缓解所释放的碳源,在清洁发展机制(CDM)等碳汇交易的机制下获得收益。文章以山西省平朔煤矿企业为研究地点,采用换算因子连续函数法计算出平朔煤矿企业通过植树造林产生的现有碳汇量为2.54万t,未来15年内的碳汇增长量为3.76万t,以80元每吨的价格计算,评估出现有碳汇的经济价值为202.94万元,未来15年内碳汇增长量的的价值为300.79万元,总碳汇价值量为505.73万元。总结得出结论:平朔煤矿企业通过植树造林所产生的碳汇有巨大的经济潜力。
With the signing of the “Kyoto Protocol”, reducing greenhouse gas emissions such as CO2 and the trend of slowing global warming have become the focus of attention of all countries in the world. Coal as the main source of China’s coal is the largest source of carbon. Through afforestation, coal mining enterprises can, on the one hand, rehabilitate damaged mining environment and on the other hand, can mitigate the released carbon source through the huge carbon sequestration function of forests and benefit from the mechanism of carbon sink trading such as CDM . Taking the Pingshuo coal mine in Shanxi Province as a research site, the conversion factor continuous function method is used to calculate the existing carbon sink produced by afforestation in Pingshuo coal mine is 25,400 tons. The growth of carbon sink in the next 15 years is 37,600 tons t to 80 yuan per ton price, the assessment of the economic value of carbon dioxide was 2.2094 million yuan, the next 15 years, the value of carbon sequestration growth of 3.0790 million yuan, the total value of carbon sequestration was 5.0573 million yuan. In conclusion, the conclusion is that there is huge economic potential for the carbon sequestration produced by the Pingshuo coal mines through afforestation.
