基于多源数据的市域旅游流空间网络结构特征——以洛阳市为例

以洛阳市为研究案例区,通过对网络大数据和社会调研数据的融合、挖掘,文章基于社会网络和空间统计分析方法探究洛阳市旅游流空间网络结构特征。所得结论如下:①洛阳市旅游流网络空间上呈现出"单核线网状"分布形态,具体表现为主城区网络最为密集,南部伏牛山旅游区、北部黛眉山旅游区网络相对稀疏,而其它各县市旅游区网络联系极其微弱的空间分布格局。②洛阳市旅游流网络整体密度较低,结构非常松散而且分布不均衡,中心化趋势明显且对核心景区依赖性较高。洛阳市旅游流网络是典型的核心-边缘型网络,但是核心景区对边缘景区的"涓滴效应"有限。③洛阳市旅游流网络"帮派"性较强,形成了内部联系紧密、外部松散的独立结构。洛阳市旅游流网络共得到24个派系,24个派系均呈现出以"龙门石窟、白马寺、丽景门"为中心的构造特征。④根据洛阳市旅游流网络结构特征,可将洛阳市提炼为以洛阳市区为核心旅游区,北部黛眉山和南部伏牛山为次核心旅游区,其它县市为边缘旅游区的"一心两翼"空间结构。

Spatial Network Structure of the City-Level Tourist Flow Based on Multisource Data:A Case Study of Luoyang

By integrating and exploring the big data of network and social survey data,this article takes Luoyang City as research area and analyzes its spatial network structure characteristics of the tourist flows applying the social network analysis,mathematical statistics analysis and spatial analysis.Conclusions are shown as follows:1)The network structure of tourist flow shows a monocentric and reticular distribution feature,it presents dense spatial distribution in urban area.Instead,there show relatively sparse in Funiu Mountain scenic area and Daimei Mountain scenic area,and other scenic areas are extremely weak.2)Overall,tourist flow network has a low density and its structure is in a very loose state and unevenly distributed with a clear centralized trend and rather high dependency on the core scenic areas.It is a typical coreperiphery network in Luoyang,the trickle-down effect of the core scenic spots is limited on the periphery ones.3)The tourist flow has a relatively strong"Gang"character,forming an inter-connected and outer-loosened independent structure.There are 24 factions in the tourism flow network of Luoyang urban area,which presents the structural characteristics with"Longmen Grottoes,Baima Temple and Lijingmen"as the center.4)According to the characteristics of Luoyang’s tourism flow network structure,Luoyang can be refined as the core tourism area of Luoyang City,the subcore tourism areas(consisting of Daimei Mountain scenic area and Funiu Mountain scenic area),and the marginal tourism areas,which forms a"one core,two wings"tourism spatial structure.
