ABSTRACT: The analytic hierarchy process decomposes the problem into different components according to the nature of the problem and the overall goal to be achieved, and combines the factors at different levels according to the interrelationship between the factors and the affiliation relationship, forming a multi-level analysis structure model, So as to finally make the problem boil down to the determination of the relatively important weight of the lowest level (plans, measures, etc. for decision-making) relative to the highest level (the overall goal) or the scheduling of the relative order of superiority and inferiority. In this paper, 13 urban roads in Mianyang were selected as the research object. The Analytic Hierarchy Process (AHP) was used to establish the evaluation index weight judgment matrix from 3 criterion levels and 9 index levels, and the landscape evaluation system was constructed to make a comprehensive evaluation on the plant landscape of 13 urban roads. Results show that the index level of plant health, color composition, native plant community, diversity of plant landscape level and the degree of coordination with the surrounding landscape five indicators have important influence to city road plant landscape. The final evaluation result is: 6 roads were rated as second-level roads, and 7 roads were rated as third-level roads. On this basis, summarized the main characteristics of the urban road plant landscape in Mianyang, and some suggestions were put forward to guide the construction of urban road plant landscape in Mianyang.
