摘要
本文报道了浙江建德青冈常绿阔叶林的调落量及各类调落物的调落特征。６年的测定结果表明．青冈林的年均调落量为５５４７．６ｋｇ／（ｈｍ２·ａ），其中枯叶量占６８．３２％，枯枝、落果、其它调落物各占１４．８２％、１５．０４％和１．８２％。各类凋落量具有明显的季节与年际变化规律，其季节分配还具年际波动现象。各类凋落物的调落特征从一定角度反映了植物群落一般的生物学与生态学特性，以及植物对特殊环境条件的适应性。
Litterfall and its dynamics in,the forests dominated by C. glauca, in Zhejiang were studied from September 1986. to August 1992. The results show that the mean annual litterfall was 5547.6kg·hm-2·a-1. Dead leaves, dead branches, dead fruits and other components of the litter contributed to 68.32%,14.82%, 15.045% and 1.82% of the litter mass, respectively. Each of the litterfall type in the forests had evident seasonal dynamics and inter-annual fluctuation. The features of litterfall reflect general biological and ecological characteristics of the plant community to a certain degree.
