| 摘 要： | 城市立交桥绿化是以立交桥为主体进行的绿化设计，它有吸附有害气体、滞尘降尘、削减噪声、美化景观和提高行车安全性等作用。一般选择乡土植物、抗逆性强、耐荫和适应性强的树种来进行立交桥绿化。同时立交桥绿化也面临许多困难，如立交桥车流量大、通行空间有限；有害气体、粉尘污染严重；桥下光照不足，生长环境不良和人为破坏现象普遍等。立交桥绿化大致分为桥体绿化和立交桥附属绿地绿化，桥体绿化主要包括桥体墙面、桥体中央隔离带、桥体防护栏和桥柱四个部分的绿化；立交桥附属绿地绿化大致可分为边坡绿化和桥周普通绿化两种形式。现在人们已经认识到立交桥绿化的作用和面临的问题，在以后的研究学习中，立交桥绿化还会进一步的发展。

| Abstract: | Afforestation of urban flyovers regards flyovers as the main object, the design has the functions such as absorbing harmful gas, stagnating dust, cutting noise, landscaping outlook, and improving the safety of driving. The trees which are native plants, have strong resistance to harsh environment, endure the shade and have strong adaptability to afforest the flyovers are always chosen. At the same time,the afforestation of urban flyovers faces many difficulties like heavy traffic, limited space, serious of harmful gas and dust pollution, inadequate illumination below bridge,bad growth environment and popular vandalism. Afforestation of urban flyovers roughly divided into two parts which are greening of bridge body and the subsidiary land, the greening of bridge body includes the bridge metope, the central belt of bridge,the bridge guardrail and bridge colunm, the greening of subsidiary land can be divided into slope greening and ordinary greening around the bridge. Now people have realized the functions of afforesting urban flyovers and the problems they faced, in the future study, afforestation of urban flyovers will have better development. |
