公路边坡绿化的景观质量评价等级研究

Research on the Grades of Landscape Quality Evaluation on Roadside Slopes Greening

以景观三元框架及系统工程理论为依据,以美学、环境、功能三大类指标为主体公路边坡绿化景观质量评价指标体系,结合层次分析与灰色综合评价法,对成南高速公路边坡绿化工程不同标段内2个边坡的景观质量进行了系统评价。结果表明:边坡I(清泉-白果1 951km+700m处,海拔550m)的绿化景观质量等级为良好,优于边坡II(冯店-仓上1 898km+620m处,海拔620m)的中等,与实际情况相符,说明该构建的评价体系及质量等级划分方法科学可行,并能比较客观准确地反映公路边坡绿化的景观质量状况与等级,具有较强实用价值。

Based on the Tribalism of Landscape and System Engineering Theory,an index system of landscape quality evaluation on a basis of three main indexes,i.e.aesthetics,environment and function were established.The system was combination of Analytic Hierarchy Process（AHP） and Grey Evaluation Method and applied to 2 different cases in different sections of Chengnan Expressway.The results showed that slope category I（From Qingquan-Baiguo 1 951 km＋700 m,altitude 550 m） had a grade of good and the grade of slope category II（From Fengdian-Cangshan 1 898 km＋620 m,altitude 620 m） was intermediate,which was fitted with actual fact.It stated that the evaluation and grade system established in this paper were scientific and feasible,could present precisely the qualities and grades of roadside slope greening and had strong practical value.
