摘要
计量研究公路绿地的生态服务功能有助于科学评估公路绿化的无形价值。以北京市顺义区顺平路(S305)的绿化植物群落为研究对象,运用WinScanopy For Canopy Analysis冠层分析仪采集数据,研究了公路绿化常见植物及配置模式的绿量率,并建立了25种公路绿化常见植物的绿量率模型,以期为公路绿化树种选择和群落配置提供基础分析与参考。结果表明:阔叶乔木的绿量率在3.02~4.80之间,针叶乔木的绿量率集中在4~6之间,灌木植物的绿量率较小,种植紧凑的绿篱绿量率达到3.94;不同配置模式的群落绿量率大小顺序依次为:针阔混交林】阔叶林】针叶林】灌木群落。其研究结果为公路绿化建设和绿地生态效益的计量提供了科学依据。
Studying ecological service function of road green space is useful to understand intangible value of road greening.Taking communities along Shunping Road(S305) in Beijing Shunyi District as research objects and collecting data by WinScanopy For Canopy Analysis,the green quantity ratio of common road greening plants and different allocation models were studied,and green quantity ratio models of 25 plants were constructed to provide basic analyzing and reference for road greening.The results showed that the green quantity ratio of broadleaf forest was 3.02~4.80,coniferous forest was 4~6.The green quantity ratio of shrub was relatively small,but that of close planted hedge reached 3.94.The size order of different communities green quantity ratio was mixed wood> broadleaf forest> coniferous forest>shrub communities.And the study results also provide scientific basis for road greening construction and measurement of road green space ecological benefit.
