在对国内外港口—腹地关系演变研究文献综述基础上,运用灰色关联分析法,测度1997—2006年大连港—辽宁腹地系统关联特性,并分析在空间上的演变规律。结果表明:大连港—辽宁经济腹地系统关联度呈阶段性演变,表现为由中部向东西再向沿海分散的空间格局;大连港—辽宁经济腹地关联度格局趋向圈层结构;大连港与大连市关联度下降,关系进入停滞期;关联度变化受辽宁沿海港口群影响,由东西向沿海集中。
This paper,on the basis of theoretical research results about the relationships of the port-hinterland at home and abroad,measures the corelation degree of Dalian Port-Liaoning Hinterland during the period of 1997—2005 and analyzes the spatial structure evolution by grey correlation analysis method.The conclusions show: ①the correlation degree of Dalian Port-Liaoning Hinterland manifests a phase-by-phase evolution.The higher degree of association is in midland at the first stage,then it transfers to the east and west,at the third stage it goes to the coastal region.②The spatial distribution pattern of correlation degree take on circles structure.③The correlation degree of Dalian Port and Dalian City diminished,the relations have entered a period of stagnation.④Changes of correlation degree are affected by the Liaoning coastal port group.
