Evaluation on Greening Landscape Design of Urban Roads Based on AHP

To improve the visual landscape quality of urban road green, AHP is adopted to perform comprehensive evaluation of greening landscape aesthetics for street greening landscape of certain city and achieve the weight of each evaluation factor. By computation it is concluded that in defined criteria layer, the most important factor is the art of color collocation whose weight is 0.332. In the factor layer, the more important 3 factors are artistic expression of color construction, rationality of plant collocation and expression of formal beauty. In comprehensive evaluation grade of greening landscape of high side slope of urban trunk road, level II and level IV are more, while level I and level III are less. Therefore, the prime problem to be improved is to balance the function of traffic accessibility and road greening landscape of major roads.
