| 摘 要： | 根据全国第7次（2004-2008 年）和第8次（2009-2013 年）森林资源清查数据，采用IPCC法估算了我国9种主要人工林碳储量及碳密度变化规律和龄组特征，探讨了近年来主要造林树种的固碳能力。两次清查间隔期间，9种人工林平均碳密度增加了1.6 Mg·hm-2，总碳储量增加了126.89 Tg，年平均增加25.38 Tg。杨树和桉树年固碳量较高，分别为10.21、9.96 Tg·a-1，碳密度增加量分别为4.32、7.72 Mg·hm-2。2009-2013年间9种人工林各龄组的碳密度为:幼龄林（8.82 Mg·hm-2）<中龄林（24.01 Mg·hm-2）<近熟林（29.37 Mg·hm-2）<过熟林（30.89 Mg·hm-2）<成熟林（35.67 Mg·hm-2）。幼龄林和中龄林占主要人工林总面积的70.52%，具有较高的生长潜力和固碳潜力。研究结果可为我国人工林森林经营管理及碳汇功能评价提供参考。

| Abstract: | Based on the 7th (2004-2008) and 8th (2009-2013) national forest inventory data of China,we used IPCC method to estimate the carbon stocks and carbon density of 9 main plantations in China,and analyzed their characteristics of each age group,as well as the carbon sequestration capacity of different plantations in recent years.During the phrase of two inventories,carbon density of 9 main plantations increased by 1.6 Mg·hm-2,total carbon stocks increased by 126.89 Tg with an annual increment of 25.38 Mg·a-1.Among 9 tree species,Populus spp.and Eucalyptus spp.obtained the highest increment in both carbon stock and density.For Populus spp.and Eucalyptus spp.,the stock increment were 10.21 and 9.96 Tg·a-1 with the carbon density increment of 4.32 and 7.72 Mg·hm-2,respectively.Between 2009 to 2013,the values of biomass carbon density at different age groups were young plantation (8.82 Mg·hm-2) < middle-aged plantation (24.01 Mg·hm-2) < near mature plantation (29.37 Mg·hm-2) < over-matured plantation (30.89 Mg·hm-2) < mature plantation (35.67 Mg·hm-2).The sum of young plantation and middle-aged plantation area accounted for 70.52% of the total area of 9 main plantations,which suggested very high potential of carbon sequestration.The results could provide a reference for the management and evaluation of carbon sink of plantations in China. |
