摘　　要：为阐明沿海沙地不同竹种对沙地环境的适应能力及其生存策略,选择福建省漳州市赤山国有林场的花吊丝竹(Dendrocalamus minor var.amoenus)、青丝黄竹(Bambusa eutuldoides var.viridi-vittata)、鼓节竹(Bambusa tuldoides‘Swollenintrnode’)、青皮竹(Bambusa textilis McClure)4种竹子为研究对象,采用方差分析、多重比较等研究方法对其地上各器官生物量分配进行研究。结果表明:移植后经过2年,4种竹子对沿海沙地环境的适应性都有所增强。从地上部分各器官含水率来看,青丝黄竹、鼓节竹与青皮竹表现为竹秆>竹枝>竹叶,花吊丝竹表现为竹秆>竹叶>竹枝。单株地上部总生物量表现为花吊丝竹>青皮竹>青丝黄竹>鼓节竹。各器官占地上生物量的比率也有所差异,青丝黄竹、鼓节竹和青皮竹表现为竹秆>竹枝>竹叶,而花吊丝竹表现为竹秆>竹叶>竹枝。To elucidate the adaptability and survival strategies of different bamboo species in coastal sandy land.Dendrocalamus minor var.amoenus,Bambusa eutuldoides var.viridi-vittata,Bambusa tuldoides ‘Swollenintrnode',Bambusa textilis McClure were selected from Chishan National Forest Farm in Zhangzhou City,Fujian Province.and their aboveground biomass allocation was studied by variance analysis and multiple comparisons.The results showed that after 2 years of transplantation,the adaptability of the four bamboos to coastal sandy land increased.According to the moisture content of the aboveground organs,the order of Bambusa eutuldoides var.viridi-vittata,Bambusa tuldoides ‘Swollenintrnode' and Bambusa textilis McClure was bamboo stalk>bamboo branch>bamboo leaf,the order of Dendrocalamus minor var.amoenus was bamboo stalk>bamboo leaf>bamboo branch.The total biomass of aboveground parts of each plant is Dendrocalamus minor var.amoenus > Bambusa textilis McClure > Bambusa eutuldoides var.viridi-vittata > Bambusa tuldoides ‘Swollenintrnode'.The biomass ratios of different organs were also different.the bamboo stalk > bamboo branch > bamboo leaf of Bambusa eutuldoides var.viridi-vittata,Bambusa tuldoides ‘Swollenintrnode' and Bambusa textilis McClure,The bamboo stalk > bamboo leaf > bamboo branch of Dendrocalamus minor var.amoenus.
