海口市城市公园自生植物多样性研究
Species Diversity for Spontaneous Plants in City Parks of Haikou,Hainan,China
摘要
Abstract
Spontaneous plants have strong growth adaptability,can self-multiply and form a good natural landscape,which are important materials for the construction of conservation-oriented landscape.The typical-sampling method was used to investigate the spontaneous plants in 16 city parks of Haikou,so as to comprehensively understand the diversity level of spontaneous plants and provide reference for the construction of conservation-oriented gardens.The results showed that 220 spontaneous plant species belonged to 59 families and 176 genera were recorded in this research.Among them,154 plants were native plants(accounting for 70%)and 66 plants were exotic species(accounting for 30%),meanwhile,48 plants were invasive alien species(accounting for 22.27%).Asteraceae,Poaceae and Fabaceae,the largest families,played a major role in the quadrats with 75 species from 64 genera,accounting for 36.36%and 34.09%of the total genera and species of Spontaneous plants.Perennial herbs and annual/biennial herbs were the main life forms,accounting for 51.36%(113 species)and 44.09%(97 species),respectively.Spontaneous plants have strong ecological adaptability and high potential for landscape application.In the future construction of urban landscape,the existing spontaneous plants in the parks should be reasonably planned and utilized,increasing the proportion of native plants and constructing the spontaneous plants landscape with regional characteristics according to different environ-ments.关键词
