高速公路绿化综合效益评价体系

Evaluation of Integrated Benefits of Freeway Greening

高速公路绿化效益的高低是衡量绿化工程质量优劣的关键因素,而缺乏成熟、规范的高速公路绿化综合效益评价体系是导致高速公路绿化失败的主要原因。通过对现有绿化效益评价方法进行总结与分析,发现层次分析法(AHP)是评价高速公路绿化综合效益科学合理的方法。本研究拟采用AHP法,采用专家调查论证的方式,建立了评价指标体系及各层次相关元素的权重值,构建绿化效益评价的基础模型,实现对不同高速公路、同一高速公路的不同路域、不同植物配置模式等的综合绿化效益的评价及比较,促进绿化质量的提高。使高速公路绿化工程建设管理走向规范化。

Freeway greening is an important part of construction in green space and ecology.The benefits of freeway green- ing is the key to assess the level of greening project.And no perfect evaluation system of freeway greening is main reason that cause bareness again of freeway green space after greening later.By comparing and analysis,the Analytic Hierarchy Process(AHP)is a suitable way to evaluate the integrated benefits of freeway greening.The weighing of indicators to the targets including ecological,landscape,economic and society benefit is calculated by AHP and experts'consultancy way, and the basic evaluation model is designed.By this model,the integrated benefits of different freeway,different part and different vegetable configure in the freeway can be evaluated and compared,which provides an evaluating way to the e- quality of greening project,and improves the level of freeway greening project management.
