| 摘要: |
| [目的]研究广西北海市巨尾桉(Eucalyptus grandis×E.urophylla)、红锥(Castanopsis hystrix)、海南蒲桃(Syzygium cumini)、香梓楠(Michelia hedyosperma)、闽楠(Michelia macclurei )、杉木(Cunninghamia lanceolata)、马尾松(Pinus massoniana)的冠幅、生物量和碳储量情况,为该地区建立人工林优势树种选择提供科学依据。[方法]对两年生的巨尾桉、红锥、海南蒲桃、香梓楠、闽楠、杉木、马尾松进行常规的群落调查,采用收获法收集各树种的根、茎、叶、枝,通过实验手段测定其生物量、含碳率、碳储量。[结果]巨尾桉冠幅为其他树种的1.7~8.6倍,高度为3.1~6倍,基径为1.6~3.6倍;巨尾桉生物量高达17.2t·hm-2,其次海南蒲桃为3.6t·hm-2,其余树种生物量较低;巨尾桉含碳率在所有树种中居于中间水平,碳储量为其他树种的6~30倍。[结论]在同龄树种中,巨尾桉的固碳能力较强,可作为人工林生态固碳的优选树种。 |

| Abstract: |
| [Objective] Crown area,biomass and carbon storage of Eucalyptus grandis×E.urophylla,Castanopsis hystrix,Syzygium cumini,Michelia hedyosperma,Michelia macclurei,Cunninghamia lanceolata and Pinus massoniana were investigated in Beihai City of Guangxi to provide scientific support for the selection of superior tree species in order to establish the plantation forest.[Methods] Regular investigation on community structure was applied to biennial plantations of Eucalyptus grandis×E.urophylla,Castanopsis hystrix,Syzygium cumini,Michelia hedyosperma,Michelia macclurei,Cunninghamia lanceolata and Pinus massoniana.Roots,stems and leaves of these species were collected by using harvest method. Biomass,carbon content rate and carbon storage were measured by experimental methods.[Results] The crown area,height and basal diameter of Eucalyptus grandis×E.urophylla was,respectively,1.7~8.6times,3.1~6times and 1.6~3.6 times of other species. The biomass of Eucalyptus grandis×E.urophylla is the highest around 17.2t·hm-2,followed by Syzygium cumini with 3.6t·hm-2,while biomass of other species were very low. Carbon content rate of Eucalyptus grandis×E.urophylla was at the middle level among all species,but with 6~30 times carbon storage of other species.[Conclusion] The carbon sequestration of Eucalyptus grandis×E.urophylla is better than that of other tree species,which is optimal tree species used in plantation forest for ecological carbon sequestration. |
