Analysis of Spontaneous Plant Species and Floras in Urban Green Spaces in Chongqing Hi-tech Indus-trial Development Zone
摘要
Abstract
To gain insight into the species,floristic types,and distribution of spontaneous plants in urban green spaces in Chongqing Hi-tech Industrial Development Zone.A comprehensive survey and statistical analysis were conducted on the spontaneous plants in park green spaces,plaza green spaces,affiliated green spaces,and campus green spaces located in Chongqing Hi-tech Industrial Development Zone.Flora analysis was also conducted on the seed plants to provide references for the introduction and domestication of garden plants,resource development and utilization,landscape construction,and green space maintenance.A total of 243 species of spontaneous plants belonging to 185 genera and 76 families were identified in the urban green spaces of the High-tech Zone of Chongqing,including 10 species of pteridophytes belonging to 8 genera and 7 families,and 233 species of seed plants belonging to 177 genera and 69 families.The dominant families with more than 10 species included Asteraceae,Gramineae,and Lamiaceae,accounting for 3.95%of the total families,26.49%of the total genera,and 24.69%of the total species,respectively.From the perspective of the flora of spontaneous seed plant families,the distribution pattern showed both richness and concentration,with worldwide and pantropical distributions being the most prominent,accounting for 75.35%of all families.The remaining four types and five variations accounted for only 24.65%of the total families.From the perspective of the flora of spontaneous seed plant genera,the distribution pattern was mainly concentrated in pantropical,worldwide,and north temperate distributions,with a total of 101 genera accounting for 57.06%of the total genera.In urban landscape construction,priority should be given to plants with worldwide,pantropical,and north temperate distributions in terms of plant selection,introduction,domestication,development,and utilization,as they have high survival rates and good landscape effects.In the maintenance and management of urban green spaces,it is necessary to strengthen the monitoring of plants with worldwide and pantropical distributions to prevent them from escaping regulatory control and appearing in large areas as spontaneous plants,which may affect the landscape effect of urban green spaces.关键词
