城市道路树种选择艺术
摘要：随着社会的发展，城市中园林绿化已不再单纯是为了满足景观需要 ，在区域生态平衡中扮演着重要的角色。其中道路绿化是其重要的组成部分，已经成为一个城市风貌的窗口。为了更好的了解城市主要街道行道树绿化结构的状况，实地调查了XX市市区二十一条主要街道的行道树的绿化状况、行道树的空间结构、主干道行道树绿化类型、行道树健康状况，通过对所调查道路的行道树组成，了解XX市市区主要街道路绿化中的行道树绿化结构存在的问题并提出如何解决这些问题所提出的对策。

Abstract: With the development of society, the city landscape is not only to meet the need of landscape, plays an important role in regional ecological balance. The road greening is an important part of it, has become a city style window. In order to better understand the main street xxxxcity greening structure status, investigation of the twenty-one main streets in downtown xxxx street tree planting condition, the spatial structure of the trunk road, roadside trees greening types, tree health, through the investigation of road of street trees, the existence of street trees structure main street xxxxCity Road greening in the problem and proposes countermeasures are proposed to solve these problems.

1前言
行道树在城市中扮演着重要的角色，它城市森林的框架，在城市整体绿化中有不可替代的作用。选择行道树时要根据不同的需要因地制宜。行道树的配置要做到与周围的整体环境相适应，使其充分发挥行道树的园林绿化作用。两者是城市行道树绿化的重要内容，得以重视。本文通过对城市主要街道行道树，包括悬铃木，垂柳，白蜡，毛白杨，国槐，旱柳，榆树，银杏，广玉兰等树木的局部系统化调查，了解x城市主要街道行道树现存的主要问题，并且针对这些问题提出对策。
1.1城市绿化与行道树
城市绿化简单的说就是在城市中利用植物的绿化作用，把不同的乔木、灌木、地被植物有机的结合在一起，形成不同的园林景观，达到一定的绿化效果。而园林植物在整个绿化效果的同时通过自身特有的光合作用来达到改善城市环境的目的。城市绿化固然重要，它改善生态环境把人们的生活和环境有机联系。其主要原因是其整个自身的绿化属性决定它能把生活环境回归到自然状态，不仅满足了居民的需求，也发挥着它的园林价值。所以不可否认的是行道树作为园林绿化大的框架，可以想象在整个绿化生态环境中的地位和影响。城市行道树遍布在城市的每一条大街小巷，作为城市绿化系统中的基础框架，它直接贴近于人们的生活，影响人们的精神状态，可以反映一个城市的精神风貌，使城市看起来富有生机和欣欣向荣的活力，所以做好城市行道树的绿化工作非常重要，体现的是尊重自然，回归自然。城市绿化要坚持以人为本的核心，只有把基础做好才能构建和谐社会，是城市生活的基础保障之一。
