| Abstract: | Afforestation conditions and vegetation characteristics of 142 Beijing flyovers in ring road 2, 3 and 4 were investigated in this paper. The result showed that 63.16% walls of flyovers were afforested vertically using Parthenocissus tricuspidata and Parthenocissus quinguefolia, isolation parts mainly by Chinese juniper and its afforestation ratio was 69.01%. Protective railings of 58 flyovers were afforested and its afforestation ratio was 40.85 %. Posts of only one flyover have been afforested, accounted for 0.76%. |
