Evaluation of Green Construction of Highway in Northwest Plateau in the Context of"Carbon Peak and Carbon Neutral"
In view of the characteristics of fragile ecological environment and the status quo of highway green construction evaluation system in the country's northwest plateau ecological protection area,a comprehensive evaluation method of highway green construction is proposed based on grey clustering method and improved radar map analysis method.The connotation of green construction in northwest plateau ecological protection area under the background of"carbon peak and carbon neutral"is put forward through analysis.Based on PSR model and objective decomposition method,the green construction evaluation system of highway in Northwest Plateau Ecological Reserve is established from seven aspects:"land saving","energy saving","water saving","material saving","environmental protection","construction personnel management"and"carbon emission".Among them,secondary indexes such as"utilization rate of corrosion-resistant concrete","biodiversity protection","green construction management system","green construction knowledge training","site construction management","carbon reduction rate in road construction stage"are added.The combination weight of each evaluation index is determined by AHP and entropy weight method.The green construction grade is determined by grey clustering method,and then the relative advantages and disadvantages of the proposed project are analyzed by improved radar map analysis method.Finally,taking Jiading-Xihai Highway in Qinghai Province as an example,the evaluation system is applied to further verify the rationality and applicability of the evaluation system.The results show that:(1)carbon emission related indexes should be incorporated into the evaluation system of highway green construction in the Northwest Plateau Ecological reserve.(2)The main factors that determine the road green construction grade in the Northwest Plateau Ecological Reserve are carbon reduction rate,renewable energy utilization rate,site construction management and local materials rate.
