提出了基于植被生长性能、植被持续潜能、植被防灾减灾、视觉美学等4个方面功能进行公路坡面植被综合评价的方法。基于数据采集的可行性与科学性分析,筛选了能够反映以上4个功能方面的26个植被结构与生长特性指标,划分评价标准。采用层次分析法(AHP)与模糊综合评判法进行指标权重值计算,构建了评价体系与模型。利用该评价体系对吉林省江密峰-延吉高速公路几种工程措施边坡重建植被评价。结果表明,所建立的评价体系实用可行,对指导公路边坡绿化验收可提供有益参考。
The method of comprehensive evaluation of highway slope vegetation based on the functions of vegetation growth performance, sustainable potential of vegetation, vegetation disaster prevention and reduction, and visual aesthetics is proposed. Based on the feasibility and scientific analysis of data collection, we selected 26 indicators of vegetation structure and growth characteristics that can reflect the above four functions and divided the evaluation criteria. Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation method to calculate the index weight value, and build the evaluation system and model. Using this Evaluation System to Evaluate Slope Rebuilding Vegetation in Jianmi Feng - Yanji Expressway in Jilin Province. The results show that the evaluation system is practical and feasible, which can provide useful reference for guiding the greening acceptance of highway slope.
