摘要/Abstract

摘要： 基于第6次森林资源二类清查数据，运用生物量-蓄积量方程及土壤调查数据计算了南京市森林生态系统碳储量和碳密度。结果表明：南京市森林生态系统碳储量为3098 Tg。其中，植被层和土壤层碳储量分别为1357 Tg和1741 Tg。碳储量的主要特点表现为城区大于城郊区（p＜005）；不同林龄从大到小排序为：中龄林、幼龄林、近熟林、成熟林、过熟林，仅中熟林与过熟林之间差异显著（p＜005）；不同林型从大到小排序为：针叶林、阔叶林、针阔混交林，且针叶林与针阔混交林之间差异显著（p＜005）；人工林碳储量显著大于天然林（p＜005）。森林生态系统碳密度为3869 Mg/hm2。其中，植被层和土壤层碳密度分别为1692 Mg/hm2和2177 Mg/hm2，除了街道林分的碳密度明显低于其他3个功能区外（p＜005），不同林型、林龄和起源林分之间的碳密度均无显著差异（p＞005）。

Abstract: Based on the data from the sixth forest resources inventory, soil survey dates and the volumederived biomass equations. The carbon storage and carbon density of urban forest ecosystem in Nanjing were evaluated. The results indicated that, carbon storage of forest ecosystem in Nanjing was 3.098 Tg, in which the carbon storage of forest vegetationand of soil organic were 1.357 Tg and 1.741 Tg, respectively. The main characters of carbon storage in Nanjing was following: carbon storage of urban forest was significant higher than that of suburbs (p<0.05), and the carbon storage capacity of forest in different times sorted in descending order: middleage forest, young forest, nearmature forest, mature forest and overmature forest, significant difference was only found exists between the middleage forest and overmature forest (p<0.05), also the carbon storage of coniferous was significantly higher than that of the mixed forest (p<0.05), the carbon storage of plantation forest was significant larger than natural forest (p<0.05). Carbon density of forest ecosystem in Nanjing was 38.69 Mg/hm2, of which vegetation and soil organic were 16.92 Mg/hm2 and 21.77 Mg/hm2, respectively. Stand types,stand age and origin had no significant impact on carbon density (p>0.05), but the carbon density of trees planted in roadside was significant lower than that of other regions.
