摘要：21世紀(jì)以來，中國(guó)進(jìn)入快速城市化進(jìn)程。市政基礎(chǔ)設(shè)施之一的城市高架橋作為現(xiàn)代城市演進(jìn)的必然產(chǎn)物，成為城市景觀的重要組成部分，但其在解決城市交通問題的同時(shí)，也帶來一系列諸如環(huán)境污染、景觀破壞等城市問題。本文將城市高架橋在景觀語(yǔ)境下進(jìn)行剖析，從高架橋自身形態(tài)美化、廢棄高架橋的景觀利用與再生、拆除高架橋后的生態(tài)修復(fù)3個(gè)方面，結(jié)合國(guó)內(nèi)外成功的實(shí)踐案例，提出了城市高架橋的景觀優(yōu)化途徑，并倡導(dǎo)在中國(guó)推行城市市政基礎(chǔ)設(shè)施景觀化的基本理念。

　　Abstract: China has come to an era of fast urbanization since the 21st century. As a product of the modern urbanization, the urban overpass has become an important part of urban landscape. Although urban overpasses help to solve traffic problems, they also bring some urban problems such as pollution and spoiled landscape. This paper analyzed the urban overpass in the context of urban landscape and explored the landscape renovation, the landscape utilization of abandoned overpasses and the eco-restoration after the demolition of overpasses. Based on the successful cases in China and other countries, this paper also put forward some landscape optimization approaches for urban overpasses and called for the promotion of landscaped infrastructure in China.

城市高架橋景觀

　　城市高架橋（路）是為改善現(xiàn)代機(jī)動(dòng)車輛交通而架設(shè)的空間通道設(shè)施，它可同時(shí)容納多層交通干線，分別供汽車、火車、行人、輕軌等穿行，還能安設(shè)管道。

　　高架橋是城市立體交通的重要組成部分，在緩解城市中心區(qū)域交通擁擠狀況、促進(jìn)城市經(jīng)濟(jì)發(fā)展等方面發(fā)揮了重大作用。然而，與此同時(shí)，高架橋（路）也隨之帶來了一些環(huán)境問題和由于建造技術(shù)或與周邊環(huán)境關(guān)系處理不當(dāng)帶來的景觀破壞問題。本文試圖從風(fēng)景園林學(xué)的視角，通過風(fēng)景園林規(guī)劃設(shè)計(jì)的方法，探討實(shí)現(xiàn)城市高架橋（路）等城市市政基礎(chǔ)設(shè)施與城市環(huán)境和諧統(tǒng)一的景觀優(yōu)化途徑。
