利用湖南省4次(1983—1987年、1990—1995年、2003—2004年和2009年)森林资源清查数据,采用材积源-生物量法,结合湖南省现有森林植被主要树种碳含量实测数据,研究近20多年来湖南省森林植被碳储量、碳密度的动态特征。结果表明:从1987年到2009年,湖南省乔木林植被碳汇为66.40×10~6 tC,碳密度提高了5.65 tC/hm~2,阔叶林碳汇最大(48.43×10~6 tC), 其次是杉木林(9.54×10~6 tC)和松木林(6.68×10~6 tC), 各乔木林植被碳密度波动较大;除过熟林外,各龄组乔木林均为碳汇,中龄林碳汇最大,幼龄林、中龄林、近熟林植被碳密度依次提高了4.75、4.09、0.83 tC/hm~2,成熟林、过熟林分别下降了6.87、13.88 tC...

Distribution and dynamics of carbon storage and carbon density were examined in forest vegetation in Hunan Province of China, based on four forest inventories during 1983—2009 (1983—1987, 1990—1995, 2003—2004, and 2009). Inventory data consisted of biomass expansion factors and carbon concentration of existing forest types in this region. The results showed that the arboreal forests were carbon sinks with a value of 66.40 × 106 t C from 1987 to 2009. The highest carbon sink was in broad-leaved forests (48.43 × 106 t C), followed by Chines...
