| 摘 要： | 薯豆(Elaeocarpus japonicus Sieblet zucc)是一种在都江堰林区普遍分布的常绿乔木,其果实及种子为众多动物所取食.本实验在原生林、次生林、灌丛、柳杉林4种生境的边缘和内部分别释放2种不同密度的种子,考察鼠类对种子命运的影响.结果表明:(1)薯豆种子的命运以原地转移为主;(2)边缘因素、种子密度因素对鼠类捕食作用的影响并不显著;(3)总体上种子在4种生境的中位存留时间有显著性差异;(4)4种生境的种子存留数变化以及最终剩余种子数量各不相同.

| Abstract: | Elaeocarpus japonicus Sieblet zucc,an evergreen arbor,is distributed widely in Dujiangyan Forest and its fruits and seeds feed numerous animals.we have studied the function of rodents on seeds of two densities along the edge and inside of mountain,which are released in four different habitats,primary stand,secondary stand,shrubland and C.fortunei stand.The results show that:(1)The mainly fate of seeds influenced by rodents is in-site removing.(2)The impact of edge factor and density factor does not change t... |
