高速公路绿化评价指标体系及评价方法研究

通过对绿化功能的分析、分解,主要从中央分隔带绿化、边坡绿化和路侧绿化3方面来进行分类,具体选择了12个指标作为高速公路绿化评价的初拟指标,采用专家筛选对初拟的评价指标进行选择,并通过主成分分析法增强其科学性和合理性,降低因评价指标之间的相关性导致评价对象信息的重复使用,在此基础上建立了高速公路绿化评价指标体系。基于回归分析和AHP方法相结合建立了高速公路绿化评价模型,该模型运用到江苏公路绿化的实践中,能够客观地评价高速公路的绿化效果。

Research on the Indexes and Evaluation Method of Expressway Green Landscape

Expressway green landscape is an important part of the expressway systems to provide landscape scenic view and other functions such as anti-glare effect in median area,soil stability enhancement capability in slope embankment area,and environmental ecologic protection in roadside area.In order to have expressway green landscape in good quality,adequate maintenance should be routinely performed.Thus,field survey activities should be carried out to evaluate the quality of expressway green landscape.The research developed evaluation index of expressway green landscape considering the functional quality,the expert's choice and analyzing principles.Through analyzing the function of greening,a research project was summarized to develop evaluation procedures and models by use of regression method and AHP for expressway green landscape evaluation,based on expressway in Jiangsu.These models can be used to more objectively evaluate expressway green landscape.
