摘要
采用正交试验,以生长地点、器官、季节和年龄作为试验因素,对江西省内4种主要竹类植物毛竹(Phylloslachys edulis)、桂竹(Phyllostachys bambusoides)、苦竹(Pleioblastus amarus)和箬竹(Indocalamus tessellates)碳密度及时空差异进行了系统地分析。结果表明:不同器官间碳含量变异最大,地区、季节和年龄对毛竹和苦竹碳密度的影响均达到极显著水平;地域对桂竹、年龄对箬竹碳密度的影响也达到极显著水平。本研究结果对竹林碳贮量估算和生态功能计量都有重要的意义。
Based on orthogonal design including following actors such as the region,organ,seasons and age,the variation of carbon contents of 4 bamboo species in Jiangxi province were systematically analyzed.The results showed that organ was the main factor which affects variation in carbon content of bamboo species.Meanwhile,the region,season and age were extremely insignificant for Phylloslachys edulis and Pleioblastus amarus.The region to Phyllostachys bambusoides and the age to Indocalamus tessellates was extremely insignificant factors respectively.The results were importantly significant for the estimation of carbon storage and ecological benefits of bamboo forest.
