Construction Of Urban Road Landscape Evaluation Based On Analytic Hierarchy Process

With the improvement of living standards,people have a higher pursuit of spiritual civilization construction and a new understanding of urban greening.As one of the important components of urban greening,urban road greening has gradually received great attention.In fact,the greening landscape design of urban roads has a long-term impact on the overall maintenance of urban roads,social civilization and ecological environment.To build an excellent urban road green space,it is necessary to follow the evaluation system of the times as a benchmark for road green space construction.So far,many researches have focused on the urban road evaluation system.However,there are still problems remains such as lack of innovation,low operability,slow update speed,and lack of overall planning and design.In this study,we analyze the greening landscape function of urban roads,studies the objectives,principles,evaluation indicators and rationality of road greening evaluation,and develops a practical evaluation system to provide reference for the improvement of urban road green space.The specific research contents are as follows:(1)Outline the basic situation of urban road green space landscape and evaluation system.This paper summarizes the research purpose,research background and research significance of urban road green space landscape,and collects the research status of urban road green space landscape design and green space evaluation system construction at home and abroad.And then,relevant theoretical results and current situation are analyzed.In final,we compare the research status at home and abroad,combine the domestic road green space and its own situation,point out the inadequacies of domestic research,and propose improvement suggestions and suggestions.(2)Using AHP method to construct the urban road greening landscape function evaluation system.Through reviewing the literature and field surveys,two levels of aesthetic function and social function are determined,and combined with the actual situation,the indicators affecting urban road green landscape are listed.The questionnaire survey method was used to invite citizens and relevant professionals and urban road green maintenance personnel to screen indicators.The statistical analysis of the 12 most influential urban road greening landscape indicators,combined with the actual situation of domestic urban road green space,classification and development of indicators evaluation criteria.By repeatedly constructing the judgment matrix,determining the weight and testing,the road greening landscape function evaluation system is established.Combined with the questionnaire survey method,the test of the evaluation system indicators.(3)Analysis of actual cases using the evaluation system.Investigate the basic situation of road green space in Handan City,and understand the growth of tree species and tree species used in road green space in Handan City.Based on the evaluation indicators and evaluation criteria,the plant growth potential,allocation method,road green space rate and seasonal phase change of road green space in Handan City were investigated,and road green space was classified and evaluated,among which the green land rate was 40%-50%,Yingbin Avenue The green road landscape of the Central Line is better.Among the roads with green land rate of 30%-40%,Huangshan Avenue,Yanshan Road,Huaguang Avenue and Xuehan Road have better landscape effects.Among the roads with green land rate of 20%-30%,Tushan Road,Shengli Road and Caoshan Road have better landscape effects.
