1级公路绿化评价方法研究

Evaluation Approaches of First Grade Highway Green Landscape

高等级公路环境绿化在公路建设中越来越受到重视,它不仅能够美化环境,而且具有防眩、防护、生态保护的能力。为了分析、评价已建公路的工程绿化状况,对公路绿化工程进行分析评价,是非常必要和紧迫的。文中结合江苏公路绿化的具体情况,通过对其绿化功能分析,提出了基于回归分析和层次分析法的1级公路绿化的评价指标体系,并建立了1级公路绿化综合评价模型。该模型运用到江苏公路绿化的实践中,能客观地评价1级公路的绿化效果。

More and more attention has been paid to freeway green landscape in highway construction, which not only beautifies the landscapes but also has such advantages as anti-glare in median area, soil stability enhancement in slope embankment area, and environmental ecologic protection in roadside area. In order to make a good highway green landscape, adequate maintenance should be routinely performed. Thus, field survey activities should be carried out to evaluate the quality of highway green landscape. Through analyzing the function of greening, this paper summarized a research project that was to develop evaluation procedures and models by the use of regression method and AHP for first grade highway green landscape evaluation, based on highway in Jiangsu. These models can be used to objectively evaluate highway green landscape.
