摘要
采用典型抽样法,对杭州市滨水绿地植物的树种组成、物种多样性指数等进行了统计和比较。结果表明:杭州市滨水绿地植物物种丰富,共计92科186属252种。将杭州市滨水绿地分为4种类型,不同类型滨水绿地中,小型面状水景乔、灌、草、水生植物的物种丰富度最大。Shannon-Wiener指数和Simpson指数有相同的趋势,乔木层Simpson多样性指数在不同滨水绿地中数值相似,差别不大;而灌木层Simpson指数中,大型面状水景最小,草本层和水生植物层的Simpson指数中最高的为大型面状水景。
By typical sampling method, the species composition and species diversity index of plant community in the waterfront regions of Hangzhou were analyzed and compared. The results showed that： The plant species of the waterfront reigons of Hangzhou are rich and involve 92 families, 186 genera and 252 species. The waterfront regions of Hangzhou are divided into four types. In the different types,the species index richness（S） of the arbor layer, the shrub layer, the herb layer, and the water plant layer in the small planar waterscape are the biggest. The Shannon-Wiener（H） and the Simpson（D） have the same trend, the species index richness（S） of the arbor layer in different types of waterfront regions are similar; but the species index richness（S） of the shrub layer in the big planar waterscape are the smalles and the species index richness（S） of the herb layer and water plant layer of the big planar waterscape type are biggest.
