基于高速公路货流数据的重庆市区县关联网络格局研究

流空间背景下的城市与区域网络研究是当前国内外城市地理学的研究前沿与热点领域。国外研究多采用信息流、航空流作为研究城市与区域网络的主要手段。探索符合我国经济社会发展阶段的城市与区域关联网络研究具有重要理论价值和现实意义。本文采用高速公路货流数据拟合重庆区县关联网络,运用社会网络分析软件(Ucinet)分析关联网络结构。研究表明:①传统的"一圈两翼"结构逐渐向"双核"结构演化,空间结构面临重组;②主城区的主要经济联系方向为渝西方向;③横向水平联系的分布具有指向性。

STUDY ON THE NETWORK OF DISTRICTS AND COUNTIES IN CHONGQING BASED ON THE DATE OF THE HIGHWAY CARGO FLOWS

Urban and regional network study under the background of ‘Space of Flows’ is the research frontier and hot spot both at home and abroad. It is the so-called "localized space of flows" that directly acts on a certain urban and regional area. As a result, the substitute method and the dominant flow are different. Overseas studies use information flow and airline flow to match the urban and regional network, which are fit for its industrialization development stage (post-industrialization), and its dominant flow is the invisible information flow. As it is known to all, China is famous for ‘the real economy’, manufacturing industry is the primary industry type. So its dominant flow is obviously the visible cargo or population flow. To sum up, it is quite urgent to find the proper method to match the urban and regional network under Chinese social and economical development background. This article chooses the typical industrial and mountainous city-Chongqing as the case study area. According to its development history and current industry composition, this article chooses the high way traffic flow (cargo and population flow) as the dominant flow. With the help of Social network analysis software (Ucinet), this article studies on the districts and counties network in Chongqing using the data of high way cargo flows. Results show that:1) The traditional so-called "One lap two wings" structure is changing to "two cores" structure. 2) The direction of main economic ties of the main city zone is west, which shows a good future for the cooperation of Sichuan and Chongqing. 3)The distribution of lateral horizontal contact shows an obvious directivity.
