摘要
在“一带一路”倡议和“中蒙俄经济走廊”建设背景下,采用区位熵、外向功、城市流等模型研究俄罗斯东部首府的城市流强度及空间格局具有重要现实意义。研究表明:(1)俄东部城市流强度呈西高东低、自西向东衰减的空间格局。西伯利亚区的城市流强度高于远东区,表现出西西伯利亚区>东西伯利亚区>南远东区>北远东区。(2)新西伯利亚、鄂木斯克、克拉斯诺亚尔斯克3个一级大区域服务中心的对外服务主导地位显著,哈巴罗夫斯克、伊尔库茨克、符拉迪沃斯托克、巴尔瑙尔、托木斯克、克麦罗沃6个二级区域服务中心是城市联系的中坚力量,乌兰乌德、赤塔、雅库茨克、布拉戈维申斯克、南萨哈林斯克5个三级地方中心的辐射作用较弱。(3)不同首府在产生城市流时具备各自的行业优势,在信息通信、金融保险、军事安全和社会保障、教育卫生、电力燃气、文体娱乐业等领域具备专业化优势,在施工建筑、批发零售、酒店餐饮、农林猎渔、房地产、其他服务业等领域对外服务功能较弱。
Under the background of“the Belt and Road”and“China-Mongolia-Russia Economic Corridor”initiatives,this paper studied the urban flow intensity and its spatial differentiation of eastern Russia with three methods,i.e.location quotient,extroversion function,and urban flow.The results are as following.Firstly,spatially,the urban flow intensity of the eastern Russia shows a“High West,Low East”spatial pattern,which in general displays a tendency of space attenuation from the west to east.The urban flow intensity in Siberian federal district is higher than that of Far East federal district,with the order as follows:Western Siberian federal district>Eastern Siberian federal district>Southern Far East federal district>Northern Far East federal district.Secondly,“three large regional service centers”,i.e.Novosibirsk,Omsk,and Krasnoyarsk,“six regional service centers”,i.e.Khabarovsk,Irkutsk,Vladivostok,Balnauer,Tomsk,and Kmerovo,“five local service centers”,i.e.Ulan-Ude,Chita,Yakutsk,Blagoveshchensk,and Yuzhno-Sakhalinsk have emerged in the urban flow intensity pattern in eastern Russia.Finally,“seven industry departments”,i.e.information and communication industry,financial and insurance industry,public administration and military safety industry,health industry,electric power and gas industry,education industry,leisure entertainment industry have become specialization dominant departments in eastern Russia.“six industry departments”,i.e.construction industry,wholesale and retail industry,hotel and restaurant industry,agriculture,forestry,hunting and fishery industry,real-estate industry,other services industry have little industrial specialization advantages in eastern Russia.
