摘要： 以百山祖常绿阔叶林为研究对象,用种子雨收集器收集森林凋落物,对收集到的凋落物进行分类、鉴定、称量,研究百山祖常绿阔叶林的凋落量及其组成和叶凋落物的季节动态.结果表明:１)百山祖常绿阔叶林２００９年的凋落量为为４２４７.４７kg.hm－ ２ .a－ １,其中叶凋落量最多,占７１.５４％ (常绿树叶５１.３４％ ,落叶树叶２０.２０％ ) ,树皮和枝条占３.１７％ ,繁殖器官占１９畅２９％ ,杂物占６.００％ ;２)９ 个优势种均具有明显的叶凋落节律,根据其特征可分为３ 类:仅在秋冬出现凋落高峰的落叶树;仅在夏季出现高峰的常绿树;在夏季和秋冬均出现高峰的常绿树;３) 与同纬度的常绿阔叶林样地相比,百山祖常绿阔叶林的凋落量较少,这是对一定地带性环境的综合反映;４)叶凋落高峰受花期、果期的影响,同时也受台风天气的影响.
Abstract: The litterfalls of evergreen broad‐leaved forest in Baishanzu Mountain were collected by seed rain collector , and they were classified , identified and weighed.The litterfall composition and the monthly dynamics of leaf litter in the forest were also analyzed.The results show that : １) The amount of the litterfall in the forest was ４２４７.４７ kg.hm－２.a－１, with leaf litterfall of ７１.５４％ ( evergreen leaf litterfall of ５１.３４ ％ , deciduous leaf litterfall of ２０.２０％ ) , tree bark and branches of ３.１７％ , reproductive organs of １９.２９％ , debris of ６.００％ , respectively ; ２ ) The nine dominant species of litterfall had a clear leaf litter dynamics , and the evergreen trees could be classified into three types as follows : the deciduous trees had a peak of leaf litterfall in the autumn and winter ,and the evergreen trees had a peak of leaf litterfall in the summer , and the evergreen trees had a peak of leaf litterfall in the summer , autumn and winter ; ３ ) Compared with those of evergreen broad‐leaved forest located at the similar latitude , the litterfalls of the Baishanzu Mountain forest were much less , which was a composite reflection for the certain zones of the environment ; ４) Flowering and fruiting had a great effect on thedynamics of the litterfalls.Besides , typhoon played an important role on them.
