摘　　要：为更好地评价公路绿化水平,基于一般公路一般不设置中央分隔带的特点,重点研究公路路侧的景观绿化。通过对公路绿化功能的分析,采用文献资料法、综合分析法初步选取了29个评价指标,然后运用德尔菲法通过两轮专家咨询完善并建立了公路路侧景观绿化评价指标体系,该体系评价指标主要包括:安全功能、景观功能及生态防护功能。其次利用层次分析法对评价指标体系中各指标进行权重的分配,建立了综合评价模型。最后以江苏省340省道两个路段的公路路侧景观绿化评价为例进行了实证分析,进一步验证了评价指标体系的可靠性。Considering the characteristic of ordinary highway without medial strip, to better evaluate the level of highway greening, this paper focuses on studying the green landscape of highway roadside. Through analyzing the function of highway greening, this paper firstly selected 29 evaluation indexes by the method of literature review and comprehensive analysis. Then the evaluation index system of highway roadside landscape greening was established and improved with two rounds of consultation by Delphi method, which mainly includes such indexes as safety function, landscape function and ecological protection function. Next, it distributed the weight of each index by way of analytic hierarchy process, and established the comprehensive evaluation model. Finally, it further verified the reliability of the evaluation index system by empirical analysis of the greening evaluation for two sections of the Jiangsu provincial trunk highway 340.
