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4 247.47 kg?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19.29%,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.

摘  要：
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 4 247.47 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 the dynamics of the litterfalls.Besides,typhoon played an important role on them.
