高速公路绿化在公路系统中起着非常重要的作用,它不仅能够美化环境,而且具有防眩、防护、生态保护的能力,而传统的绿化评价仅仅局限于景观的评价。本文通过对绿化功能分析,专家筛选和主成分分析方法,提出了高速公路绿化评价指标体系框架。该体系评价指标主要包括:中央分隔带防眩能力、边坡防护能力、路侧生态防护性以及景观效果;并结合我国江苏公路绿化的具体情况,运用层次分析方法,建立了高速公路绿化评价方法。该方法运用到实践中能够客观地评价高速公路绿化的效果。
Abstract：Freeway green landscape is an important part of freeway system to provide landscape and other functions, such as anti-glare capability in median area, soil stability enhancement capability in slope embankment area, and environmental ecologic protection capability in roadside area. Traditionally, green landscape is evaluated based on the landscape quality. This paper develops evaluation indexes of freeway green landscape considering the functional quality, the expert's choice and the principle component analyzing. The main evaluation indices include anti-glare capability, soil stability enhancement capability, environmental ecologic protection capability, and landscape quality. A summary was made for the research project to develop evaluation method for freeway green landscape evaluation using AHP (Analytic Hierarchy Process) method based on Jiangsu freeway. These models can be used to evaluate freeway green landscape more objectively.
