虚拟网络与真实交通系统中的超链接机制——以重庆地铁站点周边餐饮功能的空间句法分析为例

Mechanism of Hyper-Link in the Virtual and Real Network——A Space Syntax Analysis on Catering Functions Around Metro Stations in Chongqing Municipality

本文主要基于大众点评网获取的餐饮业空间分布和评论数数据,应用空间句法模型对重庆地铁各站周边代表商业活力的餐饮业分布状况进行了空间分析。在已有对地铁客流量数据和地面交通流量数据分析的成果之上,交叉验证了空间句法模型对交通流量和使用功能两个方面分析的适用性。研究的结论显示重庆局域空间连接具有明显的吸引作用,自身可以反映出城市中心的等级和作为"超链接"系统的大尺度范围交通网络的连接机制。此外,基于大众点评网上的各站周边餐饮业分布和评论数信息,对比了重庆各地铁站点周边餐馆数量与评论总数和真实各站客流量及空间句法局域计算参数的差异,研究结论显示作为虚拟空间中的"超链接",网络信息技术与真实空间中的地铁系统类似,对城市空间的既有等级起到了放大作用。

This paper presents a space syntax analysis on the distribution of catering functions around metro stations in Chongqing Municipality. Based on previous research findings on the relationship between syntactical value and the passenger flow data, this research provides more empirical study on the triangular relationship between movement, function and space. The result suggests that local spatial pattern play a dominant role as an attractor. It could reveal the hierarchical of urban centers. It could also greatly affect the growth of hyper-link system which functions as linkage in metropolitan scale. Furthermore, based on the reviewing data from Dazhongdianping, this paper explores the differences of using spatial distribution data of catering functions and their reviews, and the findings indicate that the visibility in virtual space may amplify the actual usages of these functions.
