舟山群岛植物区系的研究

Research on the Regional Botanical System in Zhoushan Islands

1986～1988年连续三年在舟山群岛调查采集2072号标本,整理出维管束植物165科540属890种及变种,剔除栽培后共得自然分布的153科476属784种维管束植物资料。由此简要分析了舟山群岛植物区系的特点,并与西天目山、浙南、台湾、日本等地植物区系的关系,认为舟山群岛植物区系在性质上更接近于较低纬度的浙南区系,与日本及我国台湾比较则更接近日本南部植物区系,缺乏古老性,特有成分极少,滨海植物区系发达。

Having investigated and collected specimens in Zhoushan Islands for three years(1986～1988), the authors sorted out vascular plants of 890 species, varieties and mutations of540 genera, 165 families. Except the cultivated varieties, they have conducted vascular plantinformations of 784 species belong to 476 genera, 153 families. In dependent on these informa-tions, the characters of Zhoushan Islands Botanical System were briefly estimated. As comparedwith those botanical systems of West Tianmu mountain, South Zhejiang, Taiwan, Japan andetc., they consider that in character, Zhoushan Islands Botanical System is most similar toSouth Zhejiang Botanical System. But comparing the botanical systems of Japan and Taiwan,it is more similar to tho former of South Japan since it is short of paleophyte and hardly haspiculiar species while it's coastal botanical system is relatively flourishing.
