广州滨水绿地自生植物群落调查与园林应用潜力分析

Analysis of Spontaneous Vegetation and Potential Landscape Use on Waterfront Green Space of Guangzhou

采用样方法对广州6个湿地公园自生植物群落调查,分析物种构成、重要值与园林应用潜力。结果表明:滨水绿地自生植物共42科72属77种,其中菊科、禾本科、伞形科为优势科;生活型主要为多年生草本;优势物种有芦竹Arundo donax、南美天胡荽Hydrocotyle verticillata、纸莎草Cyperus papyrus、梭鱼草Pontederiacordata和水竹芋Thaliadealbata;观赏特性以观花类为主,色彩鲜艳且富有趣味性。推荐具有园林应用潜力的15种自生植物,配置要求适地种植和有空间层次。

A survey of spontaneous plant communities in 6 wetland parks in Guangzhou was conducted by using a sample method to analyze species composition,important value,and potential for landscape application.The results show that there are 77 species belonging to 72 genera and 42 families,among which Compositae,Gramineae,and Umbelliferae are dominant families.The life forms are mainly perennial herbs,and the dominant species are Arundo donax,Hydrocotyle verticillata,Cyperus papyrus,Pontederia cordata,and Thalia dealbata.Their ornamental characteristics are mainly flowering species with bright colors and interests.Finally,this study recommends 15 spontaneous vegetation species with potential landscape use,and the configuration requires suitable planting and spatial hierarchy.
