- 摘要:
- 以重庆道路绿地中普遍常见的香樟、小叶榕、天竺葵、黄葛树、构树5种树木为试材，利用LI-6400便携式光合测定系统测定了其在不同绿地类型的光合特性参数，并分析了其在水分利用率（WUE）、光能利用率（LUE）、CO2固定效率（CE）方面的能力，评价其改善环境的效益。结果表明：构树、小叶榕、香樟对改善道路绿地环境效益优于天竺桂和黄葛树。构树、小叶榕、香樟3种树木能更好地适应恶劣环境的道路绿地，并改善其环境。
- Abstract:
- Taking 5 kinds of trees (Cinnamomum camphora(L.)Presl，Ficus microcarpa L.f，Cinnanomum japonicum (Diels.)，Ficus virensr Ait.var.，Broussonetia papyrifera (L.)) in road green land as materials，using the LI-6400 portable photosynthesis system，its photosynthetic characteristics of water use efficiency (WUE)，light use efficiency (LUE)，carbon assimilation (CE) in different green space types were evaluated.From this three characteristics evaluated its effectiveness of improving the environment were analyzed.The results showed that three kinds of trees （Broussonetia papyrifera(L.)，Ficus microcarpa L.f，Cinnamomum camphora(L.)Presl) improved unit subsidiary green space carbon sequestration and released oxygen benefits than Cinnamomum japonica and Ficus virensr Ait.var.Broussonetia papyrifera (L.)，Ficus microcarpa L.f，Cinnamomum camphora (L.) Presl could better adapt to bad environment of the road green space，and to improve its environment.
