椿叶花椒为湖南重要的速生珍贵乡土阔叶树种.通过对23 a生天然林的调查分析,发现椿叶花椒的高生长在第5 a时进入速生期,15 a后生长速度放慢;胸径的生长在第10 a开始进入速生期,20 a后胸径生长开始下降,其平均连年生长量在13 a时最大,为1.05 cm,椿叶花椒材积的生长在15 a后进入速生期.材积的连年生长量在20 a时达到高峰,且持续时间长达10 a,比胸径连年生长量的最大值出现时间推迟8 a;林分生物量不受林分年龄的影响,均变现为树干>树根>树枝>树叶这样一条规律,且树干生物量占总生物量的58%以上,林分生产力高于湿地松、杉木,这将为湖南省营造椿叶花椒速生丰产林提供科学依据. 相似文献
