摘要: 在实地调查的基础上,对浙江舟山东福山岛的植物多样性及区系组成进行了分析研究。结果表明:东福山岛共有野生种子植物133种,隶属于53 科101属,最大科(物种数5)排序为菊科Compositae,蔷薇科Rosaceae,毛茛科Ranunculaceae,桑科Moraceae和大戟科Euphorbiaceae,多数为世界广布性成分;在中国15个分布区中占有11个区系类型,总体数量相对同纬度中国大陆贫乏,其中泛热带分布、北温带分布占主体,东亚分布为辅。热带成分共60属,占总属的59.41%,温带成分共41属,占总属的39.81%,表现从热带向温带过渡的趋势,说明地理成分具有一定起源复杂性,符合海岛植物丰富度少于大陆的植物地理学一般规律;海滨植物区系发达,但缺乏起源古老的孑遗植物,与日本植物区系亲缘关系密切,同时归化植物种类日渐增多,还印证中国大陆物种新分布2种,发现中国大陆物种新分布3种,发现浙江新分布1种。图1表3参17Abstract: As field survey, plant diversity, floristic composition, and characteristics of Dongfushan Island in Zhoushan, Zhejiang Provience, were studied. Region was made by route visual estimation method in March-May, 2013. The result showed 133 species of wild seed plants belonging to 53 genera and 101 families. The largest families ( 5 species) were ranked as Asteraceae, Rosaceae, Ranunculaceae, Moraceae, and Euphor-biaceae, and were mostly cosmopolitan occupying 11 of 15 distribution types found in China. Compared to similar latitudes, the total number of distribution type was relatively few than that of the similar latitudes. Here, the Pantropical Distribution and the North Temperate Distribution dominated, while the East Asian Distribution followed. For the total number of generae tropical components consisted of 60 genera, or 59.41% in the total genera, and the temperate components consisted of 41 genera, or 39.81%.The flora of coastal plants grew well, but there was a lack of precious ancient plants. Floristics were closely related to Japan, but naturalized plant species were increasing. The maximum value of discovery was two species distributed in mainland China reported were confirmed, and three species distributed in mainland China and 1 species distributed in Zhejiang Province were found. Thus, there was a transition from tropical to temperate zones with geographic complexity showing that island plant richness was less than the mainland. [Ch, 1 fig. 3 tab. 17 ref.]
