辽宁省港口体系时空演化分析及驱动机制研究

摘要

运用赫芬达尔－赫希曼指数和灰色关联度计算了辽宁港口体系2000—2010年空间格局演化过程，并对驱动港口体系时空演化的机制进行了探究。研究结果表明：港口体系由大连港独大演化为大连港与营口港“双足鼎立”的发展格局；各类货物的集中度除煤炭、粮食略有上升以外，都呈下降趋势；与腹地的关联度，大连港由东部向西北部转移，营口港由临近区域向沈大交通线扩散，锦州港由分散向集中演变，丹东港逐步覆盖整个中、东部地区；自然及区位条件、腹地经济发展需求、基础设施配套以及外部环境及政策导向驱动了辽宁港口体系时空演化。%This article employs Herfindahl-Hirschman index and the grey correlation analysis to calculate the spatial pattern of Liaoning coastal ports system during 2000—2010 , and explores the spatial-temporal evolution driving mechanism of the system .The main discoveries include:(1) The Liaoning provincial coastal system is cur-rently consists of Dalian harbor and Yingkou harbor .This has changed the situation that the previous system used to be based solely on the Dalian harbor .(2)The concentration ratio of transport cargos is declining except for coal and food.(3) The correlation with hinterland implies:Dalian harbor is transferred from the east coast to the northwest , Yingkou harbor has spread from adjacent domains to the traffic line between Shenyang and Dalian ,Jinzhou harbor e-volves from decentralization to centralization , Dandong harbor is gradually covering the middle and the east parts of its region.(4)Thus, many factors such as natural geographical conditions , demand of hinterland economic develop-ment, supporting infrastructure constructions as well as the external environment and policy orientation , are driving the spatial-temporal evolution of Liaoning coastal ports system .
