| 摘 要： | 随着网络社会不断崛起,城市空间内涵发生了明显改变,已经成为人文地理学研究的新的重要内容。通过改进重力模型,基于有向加权网络分析方法以及BRIM算法,探讨了渤海海峡跨海通道建设前后山东半岛城市群与辽中南城市群物流网络结构的演变过程,研究发现：①渤海通道建设主要影响城市低等级物流联系,对高等级网络的影响局部集中在辽中南南部和山东半岛东部且自身物流规模较大的城市之间,其中大连、沈阳以及青岛、烟台、潍坊、济南等少数重点城市之间垄断了大量的物流资源;② 通道建设促进了“双通道双向合成流”格局形成,在各自城市群内部,物流结构将出现陆、海方向上的分离性变化,大连、烟台作为通道门户城市的地位逐渐确立;③ 首位离心流、向心流格局在演变过程中均表现出渤海通道指向性,仅有沈阳?济南、沈阳?淄博、大连?青岛、鞍山?潍坊等少数城市之间保持了常态化互惠关系,但互惠程度并不对称,辽中南地区城市的物流输出规模普遍高于具有互惠关系的山东半岛城市,前者表现为典型的“双核-边缘”结构,后者具有多极网络化特征;④ 通道建设前后山东半岛城市群的物流城市类型保持稳定,辽中南地区的向心流主导型城市则不断向铁岭、抚顺、本溪等东北部城市蔓延;⑤ 大连在渤海通道建设后首次与烟台、青岛等山东半岛城市群东部城市实现了同一子群结构衔接,总体上优化了山东半岛与辽中南城市群的物流空间格局。

| Abstract: | With the rise of the network society, the connotation of urban space has changed significantly, and it has become a new important content in the study of human geography. In this paper, the gravity model is improved, based on the method of directed weighted network analysis and BRIM, and the evolution of the logistics network of the Shandong Peninsula and the Central and Southern Liaoning urban agglomerations are discussed before and after the construction of the Bohai Strait cross-sea channel. We found that: (1) After the construction of the cross-sea channel, urban low-level logistics links will be mainly affected, and the impact on high-level networks will be concentrated on cities that have large logistics scales and located in the southern part of central and southern Liaoning and the eastern part of Shandong Peninsula. Among them, a large quantity of logistics resources are monopolized by a few key cities such as Dalian, Shenyang, Qingdao, Yantai, Weifang and Jinan. (2) The “two-channel two-way synthetic flow” will be formed with the construction of the channel. Within the respective urban agglomerations, changes in the logistics structure in the land and sea directions have begun to emerge, and further the status of Dalian and Yantai as gateway cities will be established. (3) The pattern of primary centrifugal/centripetal flow has directivity towards Bohai channel in the evolution process. Normalized reciprocal relationships are maintained among a few cities such as Shenyang?Jinan, Shenyang?Zibo, Dalian?Qingdao and Anshan?Weifang, but the degree of reciprocity of urban logistics is asymmetric. In terms of cities with reciprocal relationships, the logistics output of cities in central and southern Liaoning is generally higher than that of Shandong Peninsula. The former is characterized by a typical “dual-core-edge” structure, and the latter by multipolarity. (4) Before and after the construction, the types of logistics cities in the Shandong Peninsula urban agglomeration remained stable. The centripetal-flow-oriented cities in the central and southern Liaoning urban agglomeration continued to spread. (5) After the construction, Dalian will be classified into subgroup 3 firstly, while the sub-group structure of the inter-regional urban agglomeration will be improved by the Bohai Strait cross-sea channel together with Yantai and Qingdao, which optimized the logistics spatial pattern of the Shandong Peninsula and the Central and Southern Liaoning urban agglomerations. |
