摘要：城市绿化标志着一座城市的发展进程和现代化程度，随着城市人口的剧增，相应的建筑也被大量的建造，而在短时间内扩大建筑面积则会导致绿化用地大量缩减，出现城市的建筑用地与绿化用地相冲突的情况，生态环境的质量得不到保证。与此同时，城市的快速建设导致城市间通行的不便，为缓解交通压力，高架桥作为快速交通的主要载体被大量投入建设，但仅用钢筋水泥所建造成的高架使城市缺少生气。因此，垂直绿化的出现不仅缓解了城市绿化用地紧张，而且也给了人们提供了与自然相接触的机会。本文通过调研、比较、分析，清晰了解高架绿化植物生长的环境特点，并进行植物种植的合理选择，通过实例加以阐述说明城市高架绿化环境与植物的合理选择。74088

The environment of urban elevated greening and reasonable plant selection

Abstract：Urban Greening marks the development of a city and the degree of modernization, with the city's population increasing, the corresponding construction has also been a lot of construction, and in a short time to expand the building area of green land will lead to reduce the number of city building land and green land in conflict situations, the quality of ecological environment can not be guaranteed。 At the same time, the rapid construction of the city's leading city traffic inconvenience, to alleviate traffic pressure, the viaduct as the main carrier of rapid transit is a lot of investment in construction, but only with reinforced concrete construction caused by the elevated city lack of anger。 Therefore, there vertical greening not only alleviate the city greening the tension, but also to provide people in contact with natural opportunities。 Through investigation, comparison, analysis, a clear understanding of the environmental characteristics of the elevated green plants, and plant species The reasonable selection of plant is illustrated by examples, and the reasonable choice of urban elevated greening environment and plant is explained。

Key words: Vertical greening; Viaduct; Plant selection; Living environment
