摘要: 研究林分碳储量对了解一个地区森林生态系统服务功能和碳汇林分经营具有重要意义。本研究以上海黄浦江上游水源涵养林杜英、香樟、马褂木和黄山栾树等4个主要树种为对象,构建了4个树种林木生物量方程,并对4个树种林分生物量(乔木层、凋落物层)碳储量和土壤碳储量进行了估测。结果表明,4个树种的胸径生物量方程拟合效果较好(R2>0.9)。9年生人工林生态系统总碳储量分别为杜英117.32 t·hm-2、香樟127.38 t·hm-2、黄山栾树80.93 t·hm-2、马褂木105.87 t·hm-2。在杜英、香樟、黄山栾树和马褂木林总碳储量中,乔木层碳储量所占比例分别为35.1%、44.6%、35.2%和19.0%,凋落物层碳储量所占比例分别为1.2%、1.9%、1.2%和0.6%,土壤碳储量(0~40 cm)所占比例分别为63.7%、53.5%、63.6%和80.4%。这些人工幼龄林现在处于快速生长阶段,具有较高的固碳潜力。

Abstract: To investigate the carbon storage and its distribution in forest ecosystem is essential for assessing the ecosystem services and managing carbonsink forest at local and regional scales. Elaeocarpus sylvestris, Cinnamomum camphora, Koelreuteria integrifolia, and Liriodendron chinense are the main tree species in the plantations for water resources conservation in upper reaches of Huangpu River, Shanghai. In this study, the biomass equations for these tree species were established, and the carbon storage of tree biomass, forest floor, and soil (0-40 cm) in these 9 year-old stands were estimated. There was a good relationship between the individual tree biomass and the diameter at breast height for these tree species, with the coefficient of determination (R2) >0.9. The total carbon storage in the four tree stands were 117.32, 127.38, 105.87, and 80.93 t·hm-2, among which, tree biomass carbon accounted for 35.1%, 44.6%, 352%, and 19.0%, forest floor carbon accounted for 1.2%, 1.9%, 1.2%, and 0.6%, and soil carbon accounted for 63.7%, 53.5%, 63.6%, and 80.4%, respectively, which indicated that these young plantations were at fast-growing stage, with a great potential of carbon sequestration.
