中文摘要：
运用Huff模型计算辽宁各沿海6个港口对腹地城市影响势能值,对1995-2009年辽宁沿海港口腹地空间演变进行定量研究,并对影响沿海港口腹地空间演变的驱动要素进行定性分析。结果表明：腹地空间演变方面,东北地区逐步由大连港的单一腹地转变为多个港口的混合腹地,大连港腹地沿哈大交通线逐步转变为营口港腹地,腹地逐步减小,营口港腹地逐步扩大,地方性港口锦州港与丹东港主要服务周边城市,腹地变化并不显著;对各港口影响势能变化趋势表现为,大连港对东北地区的影响势能开始下降,尤其是辽宁省内及周边地区下降较为明显,营口港对＂T＂字形交通线及两侧的影响势能逐步提升,锦州港除对自身腹地影响逐步稳固以外,腹地空间也有向辽中地区逐步扩展的趋势,丹东港对东北大部地区的影响势能均呈上升态势,尤其以东北中东部地区上升较为显著。区位条件、交通基础设施建设、港口城市影响力提升和政策规划引导是影响辽宁沿海港口腹地空间结构演变的主要影响因素。
英文摘要：
Following the acceleration of the economic globalization, marine transportation has become the main way of international goods trade. As a result, the port becomes an important influence factor of the economic development which causes more attention concern. In the study, the Huff model was employed to calculate the potential-energy value of the influence which the six ports along the Liaoning coast act on the hinterland city. Then, a quantitative estimate about the spatial evolution process of the port hinterland along the Liaoning coast was performed in 1995-2009. Finally, we qualitative analyzed the driving factors of spatial evolution of the port hinterland. The result showed that： 1） The spatial distribution of the port hinterland in the study area has changed a lot during the past 15 years and the study area has been changed from the single hinterland of Dalian port to a mixed-hinterland of several ports. The hinterland ever belonged to Dalian port along the traffic line be-tween Harbin and Dalian has converted to the hinterland of Yingkou port which caused a decrease on the ex- tent of hinterland in Dalian port and oppositely an increase on the extent of hinterland in Yingkou port. Some local ports （such as Jinzhou port and Dandong port） mainly serving for the surrounding hinterland cities has not experienced a significantly variation on the extent of hinterland. 2） Based on the calculation result of the Huff model, the influence potential-energy value of the six ports has also changed. According the potential-en-ergy value, the influence of Dalian port on the study area decreased in the past years, especially the influence on Liaoning Province and surrounding areas which has experienced an obviously reduction. The Yingkou port has an increased influence along and both sides of the T-shaped traffic line, which make the Yingkou port a more and more important position among the six ports. The influence of Jinzhou port onits original hinterland has become more stable than past years. In addition, th
