| 1 | 西双版纳不同复合农林模式橡胶林碳储量及固碳潜力显示文摘以新垦植橡胶林、成熟橡胶林、高海拔橡胶林为研究对象,对其进行人为固碳增汇管理,比较三种复合农林模式橡胶林与同条件下橡胶纯林的植被碳储量及其未来固碳潜力,并分析三种复合农林橡胶林土壤碳储量。植被生物量碳储量通过各类增汇植物的生物量回归模型、热带树种生物量通用模型、异速生长模型进行拟合预测;土壤碳储量通过土壤剖面分层采样(0~10 cm,10~20 cm,20~30 cm,30~50 cm,50~100 cm)进行估算。研究显示:1.复合农林橡胶林现存生物量碳储量为1.19~52.89 t/hm^2,10 a后固碳潜力为1.28~106.08 t/hm^2,20 a后固碳潜力为2.23~233.89 t/hm^2;2.林下添加增汇植物后土壤碳储量显著高于橡胶林,新垦植模式中,橡胶+大叶千斤拔土壤碳储量比橡胶林增加54.95 t/hm^2;成熟橡胶林模式中,橡胶+大叶千斤拔土壤碳储量比橡胶林增加35.58t/hm^2,橡胶+可可土壤碳储量比橡胶林增加4.33 t/hm^2。结果表明:构建复合农林橡胶林可总体提高橡胶林植被碳储量及固碳潜力,提高土壤碳储量,但增汇植物种类、种植密度、生长速度不同,固碳潜力大小不一。 | 莫慧珠 沙丽清 | 2016 | 山地学报2016，34，6： | 4 |
| 2 | Carbon sequestration capability of Fagus sylvatica forests developing in the Majella National Park (Central Apennines,Italy)显示文摘Terrestrial ecosystems represent a major sink for atmospheric carbon(C) and temperate forests play an important role in global C cycling, contributing to lower atmospheric carbon dioxide(CO_2) concentration through photosynthesis. The Intergovernmental Panel of Climate Change highlights that the forestry sector has great potential to decrease atmospheric CO_2 concentration compared to other sectoral mitigation activities. The aim of this study was to evaluate CO_2 sequestration(CO_2 S)capability of Fag us sylvatica(beech) growing in the Orfento Valley within Majella National Park(Abruzzo,Italy). We compared F. sylvatica areas subjected to thinning(one high-forest and one coppice) and no-management areas(two high-forests and two coppices). The results show a mean CO_2 S of 44.3 ± 2.6 Mg CO_2 ha^(-1)a^(-1),corresponding to 12.1 ± 0.7 Mg C ha^(-1) a^(-1) the no-managed areas having a 28% higher value than the managed areas. The results highlight that thinning that allows seed regeneration can support traditional management practices such as civic use in some areas while no management should be carried out in the reserve in order to give priority to the objective of conservation and naturalistic improvement of the forest heritage. | Loretta Gratani Luciano Di Martino Anna Rita Frattaroli ANDrea Bonito Valter Di Cecco Walter De Simone Giorgia Ferella Rosangela Catoni | 2018 | Journal of Forestry Research2018，29，6： | 0 |
