城市旅游流时空网络模型研究与应用

Research and Application of Temporal and Spatial Network Model for Urban Tourism Flow

当前,旅游流常用网络结构模型和时空路径模型进行分析,网络结构模型能较好地描述旅游流的流量与流向等特征,却难以描述其时空动态变化;而时空路径模型能较好地描述单个旅游者的时空行为,却难以描述其整体的旅游流流量与流向。针对上述问题,本文提出了城市旅游流时空网络模型,较好地克服了单一的网络结构模型或时空路径模型均难以同时表达旅游流的时空与集聚不足的问题。最后以天津市为例,基于通信大数据,对天津市旅游流时空网络进行了动态构建与分析。

At present,network structure model and space-time path model are analyzed in the tourism flow.However,network structure model can better describe the flow and flow characteristics of the tourism flow,but it is difficult to describe the dynamic characteristics of its space-time. And space-time path model can better describe the space-time behavior of individual tourists,but it is difficult to describe the overall flow and flow characteristics of tourist flows.Aiming at the above questions,this paper presents a space-time network model of urban tourism flow and it can better overcome the problem that the single network structure model or space-time path model is difficult to express the space-time behavior and agglomeration characteristics of tourism flow at the same time.Finally,taking Tianjin as an example,the space-time network model of tourism flow in Tianjin is constructed dynamically based on the big data of communication.
