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126.89Tg,年平均增加25.38Tg。杨树和桉树年固碳量较高,分别为10.21、9.96Tg·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。
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 9main 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 9main 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 9tree 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 9.96Tg·a^（-1） with the carbon density increment of 4.32 and 7.72Mg·hm-2,respectively.Between 2009 to 2013,the values of biomass carbon density at different age groups were young plantation（8.82Mg·hm^（-2）） middle-aged plantation（24.01 Mg·hm^（-2）） near mature plantation（29.37 Mg·hm^（-2）） over-matured plantation（30.89Mg·hm^（-2）） mature plantation（35.67Mg·hm^（-2））.The sum of young plantation and middle-aged plantation area accounted for 70.52% of the total area of 9main 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.
