Abstract:

This article takes the old city area of Jishou City as the research object. Based on the literature research and field surveys, combined with relevant route selection studies, we evaluate the urban roads from the perspectives of ecological landscape and traffic conditions. The evaluating indexes include seven factors: the road greening rate, the surrounding landscape, the types of connected land, the road grades, the width of street front, the traffic flow, and non-motorized vehicle lane and sidewalks. Then through the questionnaire survey and expert evalution, combined with analytic hierarchy process (AHP),  we establish the weight of each index. Finally, by scoring each index and calculating the weighted suitability value of each road, we rank the urban greenway suitability into levels, and proposes a greenway grid with two horizontal and two longitudinal lines, which provides a basis for the urban greenway route selection.

Key words: greenway, suitability, AHP, landscape garden
