摘要
基于流动空间,借助GIS、Matlab和Gephi等技术手段,构建多元流动要素网络,分析港—城网络体系空间重构的特征与过程,并探讨其作用机制。结果表明:(1)流动空间重塑了港—城体系的结构和方向,核心港口城市能级提高,港口城市间由单纯的竞争关系变为新型的竞合关系;社团结构组合变化促进多元流网络联系广度和深度不断拓展,枢纽港及其城市溢出效应进一步扩大。(2)多核心的扁平化结构取代原来的金字塔结构成为流动空间视角下港—城网络体系的典型特征,其中上海、深圳、广州和天津等综合性港口城市的辐射作用凸显。(3)港—城网络体系空间重构的作用机制突出表现为"内外统筹"影响下的枢纽港及其城市主导作用明显、"相辅相成"推动下的新兴港口城市快速成长及港口城市间实现自组织协调。物质流和虚拟流越来越成为港—城网络体系演化的决定性因素,且虚拟流的冲击程度更为显著。
Based on the flow space and by the means of GIS,Matlab and Gephi,this paper constructs a multi factor flow network,analyzes the characteristics and process of spatial reconstruction of port-city network system,and discusses its mechanism.The results show that:1)The flow space reshapes the structure and direction of the port-city system,the energy level of core port cities is improved,and the relationship between port cities is changed from simple competition to competition-cooperation relationship;the combination change of community network promotes the continuous expansion of the breadth and depth of multi-flow network,and the spillover effect of hub port and its city is further expanded.2)The multi-core flat structure replaces the original pyramid structure and becomes a typical feature of port-city network system from the perspective of mobile space.Among them,comprehensive port cities such as Shanghai,Shenzhen,Guangzhou and Tianjin play an important role.3)The mechanism of spatial distribution of port-city network system is characterized by the obvious leading role of hub ports and cities under the influence of"internal and external coordination",the rapid growth of emerging port cities driven by"complementary"and the realization of self-organization and coordination among port cities.Material flow and virtual flow are becoming more and more decisive factors in the evolution of portcity network system,and the impact of virtual flow is more significant.
