西安市道路绿化树种的调查研究

An Investigation on Greening Tree Species Along the Roads of Xi′an

环境质量的好坏关系着一个城市的发展和进步,西安是一个文明古都,有着悠久的历史和文化,是全国的旅游热点城市,但西安目前的绿化与其它发达城市相比还有很大差距,存在绿化树种种类单一、彩叶树种很少、道路绿化结构简单、管理薄弱等问题。文章通过调查分析,提出了西安市的道路绿化必须从丰富绿化树种种类着手,增加常绿树的应用比例,建立生态健全的立体绿化结构,加强法制建设,增强园林绿化的养护管理,同时提出一些可在西安市道路绿化中推广应用的彩叶树种种类。

The environments quality plays a significant role in the development of a city. Xi＇an, boasting its prolonged history and rich culture, is an ancient city of civilization and now, a hot tourism destination of China. Compared with other developed cities in street greening, there are still problems such as monotonous greening trees, being short of colorful-leafed trees, simple planting structure, and weak administration and so on, making Xi＇an left behind. On the bases of practical investigation, several suggestions like increasing the proportion of evergreen trees, establishing three dimensional greening structure with ecological soundness, strengthening legal construction and improving administration, etc. were put forward. It was also suggested to expand color-leafed tree planting in the streets of Xian.
