为了研究城市森林草本植物多样性及其与冠层结构的关系,本文对上海崇明岛人工林1公顷样地的草本植被结构进行了调查分析,结果表明:(1)样地内共有草本植物40种,分属20科39属,以菊科种为主。(2)不同群落林下草本植被组成有明显差异,各群落林下草本植被优势种不同,物种多样性指数也不一样。香樟群落林下草本植物多样性指数最大,重阳木群落林下草本植物多样性指数最低。各指数变化趋势一致,均表现为常绿阔叶林(香樟林)>落叶针阔混交林(水杉-重阳木林)>落叶阔叶林(梧桐林)>落叶阔叶林(重阳木林)。 (3)同一群落林下草本植被组成有差异,不同密度梯度以及不同郁闭度梯度下各草本植被物种多样性指数均呈先...

In order to study the relationship between herbaceous plant diversity and canopy structure in urban forest, this paper investigated the structure of herbaceous plants in a 1 hm2 plot of Chongming Island in Shanghai. The results showed that: (1) There were 40 species of herbs in the plot which belonged to 20 families and 39 genera, and the species of Asteraceae family were dominant. (2) The understory herbaceous structures, the dominant herbaceous species and their species diversity indexes in different communities were significantly different. ...
