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.
