浙江省河道植物调查研究

Investigation on the Riparian Plant Species in Zhejiang Province

为了研究植物措施在河道生态治理中的重要作用,对浙江省平原、山区、半山区、海岛等4种类型的河道植物进行调查.结果表明:浙江省有河道维管束植物1 033种(包括种下分类等级),隶属138科.其中蕨类植物18科37种,裸子植物2科7种,被子植物118科989种.按植物生态学特性分类,中生植物693种,湿生植物210种,水生植物130种.在水生植物中,挺水植物75种,沉水植物25种,浮叶根生植物19种,漂浮植物11种.根据河道植物的适应性、群落亲和度、功能性和景观性原则,筛选出95种作为浙江省河道生态整治的推荐植物.

Investigation on riparian plant species along 4 types of rivers in Zhejiang Province was made, i. e. ,the rivers in plain area, mountain area, hilly area and in the island area, to study on the role of vegetative measures in ecological amelioration of rivers. It was showed by the results that there were 1 033 vascular plant species and subspecies growing in riparian habitats in Zhejiang Province, belonging to 138 families. Among those there were 37 species of ferns from 18 families 7 species of gymnosperm plant species from 2 families, and 989 species of angiosperm plant species from 118 families. Based on the ecological characteristics, these riparian plants can be classified as 693 species of common plants,210 species of hygrophytes and 130 species of hydrophytes. Among the hydrophytes, there were 75 species of emergent plants, 25 species of submerged plants, 19 species of floating - leaved plants, and 11 species of floating plants. Consequently, 95 species of plants were screened and were recommended be utilized for ecological amelioration of rivers in Zhejiang Province according to their ecological adaptability ,community appetency, comprehensive functions and the landscaping values.
