摘　　要：以百山祖常绿阔叶林中三个优势种麂角杜鹃、尖连蕊茶和木荷为研究对象，研究2009～2012年其花及果实凋落的年际变化与季节动态，结果表明：1）在花凋落数量上，麂角杜鹃和木荷有明显大小年现象，尖连蕊茶则无；2）在果实凋落数量上，麂角杜鹃有明显大小年现象，其他两树种则无；3）从凋落季节上看，麂角杜鹃和尖连蕊茶花凋落集中于春末，木荷则在秋初；4）果实的异常凋落与灾害性天气有密切关系。This study describes the dynamics of flower and fructification of three dominant species, includingRhododendron latoucheae,Camellia cuspidata andSchima superba, from 2009 to 2012 in Baishanzu evergreen broad-leaved forest. The results show that： 1） From the analysis of temporal dynamics of flowers,R. latoucheae andS. superba have significant in-and-off year phenomena of flower in the plot, whileC. cuspidata doesn＇t. 2） From the analysis of temporal dynamics of fructification,R. latoucheae has significant in-and-off year phenomena of fruits, butC. cuspidata and S. superba don＇t. 3） From the analysis of seasonal variation of flowers, R. latoucheaeandC. cuspidatalittered in the late spring, whereasS. superba littered in the early fall. 4） Abnormal litter of fructification has a closed contact with unfavorable weather.
