摘　　要：传统的绿道网络构建方法大多是以绿道的适宜性分析为规划基础,存在一定的主观性。为更好地满足绿道使用的实际需求,提高绿道的使用率,以义乌市为例,首先基于多源数据选取自然生态、生活需求和绿道特征三方面因素构建绿道网络适宜性指标体系,其次通过成本连通性工具初步构建基于适宜性评价的绿道网络线路,接着引入两步路游憩轨迹数据进行热点检测及人工矫正绿道网络线路,同时将轨迹数据识别出的停留点进行网络分析,最终得到更具科学性的省级、市级、社区级三级绿道网络分级布局和驿站规划,满足了居民游憩和通勤需求。研究旨在通过多源数据量化分析构建城市绿道网络,以期对相关规划提供指导。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,fi rstly,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 identifi ed stopping points from the trajectory data are analyzed through network analysis,resulting in a more scientifi c 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.
