摘要:

采用抽样调查方法,对杭州主城区19条道路绿化树种资源进行调查,分析了杭州市城市道路绿化的树种结构及频度,计算了各道路物种丰富度指数、Shannon-Weiner指数、Simpson指数及Pielou指数。结果表明:杭州市主城区道路绿化树种资源共33种,隶属于24科31属。其中乔木12种,灌木为21种,樟(Cinnamomum camphora)与红花檵木(Loropetalum chinense var. rubrum)的出现频率超过50%,分别达60.71%与53.57%。各道路绿化树种多样性指数相差各异,多样性综合指数排名前10的为庆春东路(0.9570)>环城北路1(0.9428)>艮山西路1(0.9373)>天目山路1(0.9218)>文一西路(0.9162)>凤起东路2(0.9113)>天目山路2(0.8958)>环城北路4(0.8462)>环城北路3(0.8288)>环城北路2(0.8082)。

Abstract:

By using sampling survey method,greening tree species along 19 roads in the main urban areas of Hangzhou were investigated.The tree species structure and frequency of urban road greening in Hangzhou were analyzed,and the species richness index,shannon-weiner index,Simpson index and Pielou index were calculated.The results showed that there were 33 species of road greening trees belonging to 24 families and 31 genera.There were 12 species of trees and 21 species of shrubs.Among them,Cinnamomum camphora and Loropetalum chinense var.Rubrum appearance frequency is more than 50%,60.71% and 60.71% respectively.The diversity index of different road greening species is different,and the top 10 of the diversity comprehensive index are:Qingchun East Road(0.9570),>North Ring Road 1(0.9428),>West Ring Road 1(0.9373),Tianmushan Road 1(0.9218),>West Wen Road(0.9162),>East Fengqi Road 2(0.9113),>North Ring Road 4(0.8462),>North Ring Road 3(0.8288),>North Ring Road 2(0.8082).

Key words: road greening, frequency, richness index, diversity index, Hangzhou
