根据15年的调查结果，对浙江省水生维管束植物的区系与地理分布特点进行了研究。已知浙江有水生维管束植物150种，隶属于78属，42科。将78属归纳为11个分布区类型，以世界分布类型所占比例最高，热带分布属总数多于温带分布属，泛热带分布和北温带分布比例非常高。将150种植物归纳为13个分布区类型，温带分布远多于热带分布，以东亚分布类型最为突出，体现了中国-日本植物区系的明显特征。探讨了浙江水生植物的水平地带性和垂直地带性分布规律。其分布不仅与气候带有关，更与水生植物的生境的分布格局有关。最后，分析了浙江水生植物濒危种的受威胁状况。
根據15年的調查結果，對浙江省水生維管束植物的區繫與地理分佈特點進行瞭研究。已知浙江有水生維管束植物150種，隸屬于78屬，42科。將78屬歸納為11箇分佈區類型，以世界分佈類型所佔比例最高，熱帶分佈屬總數多于溫帶分佈屬，汎熱帶分佈和北溫帶分佈比例非常高。將150種植物歸納為13箇分佈區類型，溫帶分佈遠多于熱帶分佈，以東亞分佈類型最為突齣，體現瞭中國-日本植物區繫的明顯特徵。探討瞭浙江水生植物的水平地帶性和垂直地帶性分佈規律。其分佈不僅與氣候帶有關，更與水生植物的生境的分佈格跼有關。最後，分析瞭浙江水生植物瀕危種的受威脅狀況。

The floristic features and geographical distribution of aquaticvascular plants were summarized in Zhejiang Province based on 15-year investigations. There were 150 species belonging to 78 genera and 42 families in the province. Eleven areal types were classified from these genera, in which the highest proportion was cosmopolitan, followed by the tropical and then temperate. The species were classified into 13 areal types, in which East Asia element was the dominant. The proportion of temperate elements was much higher than the tropical, representing obviously the feature of Sino-Japan flora. The horizontal zonality and the vertical zonality of the aquatic plant distribution in Zhejiang Province were analysed. The distribution is not only correlated with climate zone, but is much more correlated with the pattern of habitats. Finally, we proposed a list of threatened species of aquatic plants in Zhejiang Province, with a discussion on their threatened degrees.
