摘    要:根据云南省第3次(1992-1997年)和第5次(2002-2007年)森林资源连续清查数据资料,采用生物量转换因子连续函数法,对云南省森林植被的碳储量、碳密度及其动态变化进行了分析研究.结果显示:近10年来云南省森林总碳储量由1997年的679.10 Tg(1 Tg=1012g)增长为2007年的884.11Tg,年增长率为2.67%;乔木林的碳密度由1997年的46.80 Mg/hm2(1 Mg=106 g),增长为2007年的50.58 Mg/hm2,高于全国的平均碳密度水平.云南省森林以幼、中龄林为主,占全省森林面积的65%以上,说明云南省森林植被具有巨大的固碳潜力.

Abstract:Based on the data of 3rd(1992—1997) and 5th(2002—2007) forest resources inventory in Yunnan Province,forest carbon storage,carbon density and its dynamic change in Yunnan Province were analyzed by adopting the biomass expansion factor continuous function.The results were as followed: in recent 10 years the forest carbon storage increased from 679.10 Tg in 1997 to 884.11 Tg in 2007,and the annual growth rate was 2.67%.The carbon density of arboreal forest increased from 46.80 Mg/hm2 in 1997 to 50.58 Mg/hm2 in 2007,higher than the national average level of carbon density.The forest was mainly young,middle-aged forest in Yunnan Province,its area accounted for more than 65% of the total forests,which showed that forest vegetation in Yunnan Province had great potential to stock carbon.
Keywords:forest  carbon storage  carbon density  dynamic change  Yunnan Province
