The traditional method of constructing greenway networks is mainly based on the suitability analysis of greenways, which has a certain degree of subjectivity. To better meet the actual needs of greenway use and improve the utilization rate of greenways, taking Yiwu as an example, firstly, based on multi-source data, natural ecology, living needs, and greenway characteristics are selected to construct a suitability index system for the greenway network. Secondly, a preliminary greenway network route based on suitability evaluation is constructed using cost connectivity tools. Next, the two-step recreational trajectory data is introduced for hotspot detection and manual correction of greenway network routes. At the same time, the identified stopping points from the trajectory data are analyzed through network analysis, resulting in a more scientific three-level greenway network layout and station planning at the provincial, municipal, and community levels, meeting residents’ recreational and commuting needs. The research aims to construct an urban greenway network through quantitative analysis of multi-source data to provide guidance for relevant planning.
