以福建省1998、2003、2008年连续3期森林资源固定样地清查统计数据为基础,结合不同森林类型生物量与蓄积量回归方程,对福建省森林植被的碳储量和碳密度进行估算,并进行期间的动态变化分析,其结果表明:随着福建省林业的发展,自1998年其森林碳储量有了明显的提高,人均碳密度由38.55t/hm2上升至65.65 t/hm2,已超过全国41.1 t/hm2的平均碳密度,但从其年龄结构上分析,近熟林以上的森林碳储量虽然有所增加,但其碳密度呈下降趋势,则表明近熟林以上森林质量有所下降,森林结构仍有待于进一步调整与改善.%Based on the forest inventory data from the fixed sample plots in Fujian Province in the years of 1998, 2003 and 2008, the carbon storage and density of forest vegetation were estimated and their dynamic changes during this period were analyzed with the method of regression equation between the stand biomass and volume in different forest types. The results showed the that forest carbon storage had increased obviously since 1998 with the forestry development in Fujian Province. The carbon density increased from 38. 55 t/hm2 to 65. 65 t/hm2 per capita, more than the national average 41. 1 t/hm2. However, the analysis of its age structure showed that the carbon storage of mature forest and over - mature forest increased while its carbon density decreased this result implied that the forest quality of mature forest and over-mature forest is going to decline, and further adjustment in forest structure is urgently needed.
