摘要
通过构建港口货物吸引潜力模型,预测“冰上丝绸之路”建设完成后,中国沿海港口体系针对中国-西北欧海运贸易的货运空间格局并识别货运空间类型。结果显示:在空间格局方面,吸引潜力分布呈由北向南逐次递减趋势;液化天然气、煤炭、铁矿石、木材和潜力总值具有显著的空间正相关性,石油和集装箱在空间上表现为随机分布模式;环渤海和长三角已具有一定的港口层级结构特征,东南沿海、珠三角和西南沿海低值集聚特征较明显。在货运空间类型方面,港口体系结构的重心在北部港口地区,环渤海大型港口的综合性货流聚集能力要强于其他地区,沿海港口基本符合货运规模越大,其综合货运等级越高的趋势。
This paper constructs a model of port cargo attraction potential,and predicts and analyses the spatial differentiation pattern of China’s coastal port system against China-Northwest Europe maritime trade and identifies the type of freight space under the background of full navigation of the Ice Silk Road.The results show that:In terms of spatial pattern,the distribution of attraction potential shows a decreasing trend from north to south.LNG,coal,iron ore,timber and total potential have significant positive spatial correlation.Oil and containers are randomly distributed in space.The region around Bohai Rim Region and Yangtze River Delta has some characteristics of port hierarchy.The low-value agglomeration characteristics are obvious in the Southeast coast,Pearl River Delta and Southwest coastal areas.In terms of freight space types,the focus of port architecture is in the northern port area,and the comprehensive cargo flow aggregation capacity of large ports around the Bohai Sea is stronger than that of other areas.Coastal ports basically accord with the trend that the larger the scale of freight transport,the higher the comprehensive freight grade.
