摘要
为了更好地了解野生早樱的群落特征,在野外实地调查的基础上,对福建武夷山和江苏宝华山野生早樱群落植物组成进行研究。结果表明,两地群落植物种类组成有较大的差异,共有植物64科、144属和261种,其中武夷山群落(Ⅰ)物种组成最为复杂,宝华山群落(Ⅲ)最简单;两地3个群落相似性较低,共同出现的科、属、种占全部科、属、种比例依次为52.94%、27.97%和10.48%;Raunk iaer的频度分析表明,该群落并不符合A>B>C>=<D<E频率定律,而表现出A>B>C>D>E,说明群落中种的分布不均匀且植被存在分化和演化的趋势。
In order to realize the community characteristic of Cerasus subhirtella var. ascendens better, the study was conducted in Fujian W uyi Mountain and Jiangsu Baohua Mountain based on the field investigation. The results show that the floristic composition has significant difference in different areas, which indicates the community of Wuyi Mountain （ Ⅰ ） is the most complicated and Baohua Mountain （Ⅲ） is the simplest among them, including 261 species, 144 genera, and 64 families of spermatophyte plants; the similarity of floristic composition among the communities is low, and the proportions of constant families, genera and species are 52.94%, 27.97% and 10. 48% in turn; according to the Raunkiaer frequency law of A 〉 B 〉 C 〉 = 〈 D 〈 E to analyse, the species frequency is A 〉 B 〉 C 〉 D 〉 E, which illustrates the species are uneven distribution in the communities and the vegetation has the tendency of differentiation and evolutionary.
