黑龙江省森工林区用材林不同林龄树种碳汇价值研究

Analysis on Carbon Sequestration Value of Timber Forest at Different Age in the Forestry Region of Heilongjiang Province

以黑龙江省森工林区用材林为研究对象,以黑龙江省森工林区第六次森林资源一类清查结果为基础,基于蓄积量法,研究黑龙江省森工林区用材林不同林龄树种碳汇价值。生物碳储量研究表明:黑龙江省森工林区用材林实际碳储量2.635 1×108t,中林龄和近熟林占比重比较大,而且占有绝对的优势,是该区域潜在的巨大碳库。碳汇价值研究表明:黑龙江省森工林区用材林生物碳汇价值为2.898 61×109美元,合人民币182.9亿元。同时吸收CO29.66亿t,释放O27.03亿t,释放氧价值达4 218亿元。以上数据表明,黑龙江省森工林区用材林拥有巨大的碳汇量。如果能够保护好现有的森林资源,让其自然生长,黑龙江省森工林区用材林将发挥越来越重要的碳汇功能。

This paper chooses timber forest in the forest industry region of Heilongjiang Province as the research object,and analyses the carbon value of different plantation in the region,based on the data in the sixth forest inventory of Heilongjiang forest industry region and the method of volume.The research on the biological carbon storage showed that the actual carbon storage of timber forest in the forest industry region of Heilongjiang is 26351×104t.The proportion of the middle-age forest and near-mature forest is larger,and has an absolute advantage.They are the potential huge carbon pool in the area.The study on the carbon value indicated that the carbon value of timber forest in the forest industry region of Heilongjiang is ＄289861×104,or about 18.29 billion yuan.At the same time,the amount of carbon dioxide captured is 0.966 billion ton,and the release of oxygen is 0.703 billion ton with value of 421.8 billion yuan.The above data shows that the timber forest in the forest industry region of Heilongjiang has a huge amount of carbon sequestration.If we can protect the existing forest resources in a scientific way,they will play more and more important role in carbon sequestration.
