山东沿海主要港口腹地的动态演化

Dynamic Evolution of the Main Port Hinterland in Shandong Province

港口腹地对特定区域内港口功能的合理定位和港口体系的构建意义重大,为明确山东沿海主要港口腹地的动态演化过程、特征及机制,在Huff模型基础上,运用地理信息系统(GIS)技术,构建交通运输地理信息数据库,集成网络分析法与栅格分析法,设计港口腹地动态演化模拟的技术实现路线,据此考察了山东省沿海主要港口腹地格局的动态演化。结果表明:港口腹地结构上,青岛港与日照港腹地呈现典型的以交通干线为轴线的放射型结构,烟台港腹地呈现典型的圈层结构;港口腹地演化上,2000年以来,在区域内各港腹地交相扩张的相互作用下,山东省沿海主要港口腹地格局经历了"北上—南下"的动态演化过程。

The pattern of port hinterland is of great significance for orientating port function rationally and building an effective port system in one specific region. Based on the Huff model, a transportation geographic informa-tion database was constructed by using geo-information system technology. Using grid for basic research units, a tech-nology route was designed to simulate the dynamic evolution of port hinterland by integrating network analysis and grid analysis. Then, the process, characteristics and dynamic mechanism of the dynamic evolution of the major port hinter-land pattern in Shandong Province was studied. The results indicate that, the hinterland structure of Qingdao port and Rizhao port present a typical radiation type with transportation routes as axes, while the hinterland structure of Yantai port presents a typical layer type; Influenced by the interaction of expansion of different ports, the major port hinter-land pattern in Shandong Province has experienced a “ north-south” dynamic evolution since 2000.
