| 中文摘要: |
| 为了定量分析山西省森林资源碳储量及碳汇经济价值,利用2005—2015 年3期森林资源清
查数据,采用联合国政府间气候变化专门委员会(IPCC)材积源—生物量法核算山西省森林资源碳储量及碳汇,依据当年碳汇及氧气价格计算山西省森林资源经济价值。结果表明,山西省森林碳储量从2005年的44.25 TgC增加到2015年的73.92 TgC,增长率为67.05%,天然林碳储量、碳密度及碳汇均高于人工林;山西省森林面积、碳储量、碳密度、碳汇最大的树种(组)分别为油松、辽东栎、云杉、
阔叶混;森林碳储量与森林龄组结构及碳密度密切相关,中龄林是山西省碳储量和碳汇增加的重要龄组,幼龄林具有非常大的增汇潜力;山西省森林碳汇经济价值从2010年的87.66 亿元增长到2015年
的133.59 亿元,年均增长9.19 亿元,其中,辽东栎碳汇经济价值最大,落叶松单位面积碳汇经济价值最大,刺槐碳汇经济价值增长率和单位面积碳汇经济价值增长率均最大。改善油松纯林结构,增加
油栎混交林比例,逐步向近自然顶级群落过渡,是增加山西省森林资源碳储量的关键措施。 |
| 英文摘要: |
| Shanxi Province was calculated according to the carbon sink and oxygen price of the current year. The results showed that the forest carbon storage of Shanxi Province increased from 44.25 TgC in 2005 to 73.92
TgC in 2015, with a growth rate of 67.05%. The carbon storage, carbon density and carbon sink of natural forests were higher than those of artificial forests. The tree species(groups) with the largest forest area, carbon storage, carbon density and carbon sink in Shanxi Province were Pinus tabuliformis, Quercus
wutaishanica, Picea asperata and broad - leaved mixed forest, respectively. Forest carbon storage was
closely related to age-class structure and carbon density. Middle-aged forests were identified as the key
age class contributing to the increase in carbon storage and sink, while young-aged forests possessed significant potential for future sink enhancement. The economic value of forest carbon sinks in Shanxi Province grew from 8.766 billion yuan in 2010 to 13.359 billion yuan in 2015, with an average annual increase of 919 million yuan. Among the species, Quercus wutaishanica had the highest total carbon sink economic value, Larix principis-rupprechtii had the highest economic value per unit area, and Robinia
pseudoacacia showed the highest growth rates in both total economic value and economic value per unit area. Key measures to enhance forest carbon storage in Shanxi Province include improving the structure of
pure Pinus tabuliformis forests, increasing the proportion of mixed Pinus tabuliformis and Quercus forests,
and gradually transitioning towards near-natural climax communities. |
