2015神农架生物学实习小论文 神农架区域内一年蓬适应性分布 龙振宇陈胜之*陈洁仪 (复旦大学生命科学学院,上海200433) 摘要:一年蓬原产自北美,是神农架林区内的一种入侵植物。神农架环境多样, 其海拔高度、光照强度及生物物种分布等生物、非生物因素变化较大。作为一种 典型的阳生植物,一年蓬的形态结构产生了许多适应性特征,从而实现了在神农 架区域内的广泛分布。同时,一年蓬在人类活动频繁地区似乎有更强的适应力。 我们于不同海拔、光照等条件下对一年蓬进行了各种性状的统计,试图对其适应 性进行合理解释,为今后神农架区域内一年蓬的治理给出一些建议。 关键词:阳生植物,海拔高度,抗虫性,叶序 Adaptive distribution of Erigeron annuus in Shennongjia Zhenyu Long, Shengzhi Chen", Jieyi Chen** ( School of Life Sciences, Fudan University, Shanghai 200433) Abstract: Erigeron annuus, native to North America, is a kind of invasive plant in Shennongjia Forestry District. Different biological and abiotic factors, such as altitude light intensity, species distribution, contribute to diverse environment in Shennongjia As a kind of typical sun plants, Erigeron annuus has involved adaptive features in morphological structure, which achieved its widely distributed in the Shennongjia area At the same time, we find that Erigeron annuus seems to adapt to arears of frequent human activity. In order to make a reasonable explanation of its adaptability and give some suggestion on governance of Erigeron annuus in the Shennongjia area in future we did a survey of various characteristics of Erigeron annuus at different altitude, under different lighting conditions Key words: sun plants, altitude, pest resistance, phyllotaxy 共同第一作者 Author for correspondence.
