基于可拓云模型的绿色生态型市政道路综合评价方法应用研究

Research on Comprehensive Evaluation Method of Green Ecological Road Based on Extension Cloud Model

本文从生态环保、品质提升、安全高效、绿色低碳、信息智慧5个方面来构建覆盖全寿命周期的指标体系,综合利用AHP—熵权组合赋权法、物元分析理论和云模型建立绿色生态型市政道路评价可拓云模型,并实现了绿色生态评价的可视化云图分析。最后,以重庆市广阳大道进行实例研究,结果表明广阳大道绿色生态水平处于Ⅴ级,指标落实情况较高,与该项目实际考核情况基本一致,验证了本文的可拓云模型的科学性,可为绿色生态型市政道路项目评价提供一定的科学参考。

This paper constructs an index system covering the whole life cycle from five aspects:ecology,quality,safety,low carbon,and wisdom,and comprehensively uses AHP-entropy weight combination method,matter element analysis theory and cloud model to establish green ecological road evaluation extension cloud model,and realized the visual analysis of green ecological road evaluation. Finally,a case study was conducted on Guangyang Avenue in Chongqing City. The results show that the green ecological level of Guangyang Avenue is at level V,and the implementation of indicators is relatively high,which is basically consistent with the actual evaluation of the project. Thus the scientific nature of the extension cloud model in this paper is verified,which can provide a certain scientific reference for the evaluation of the project’s green ecological road project.
