北部湾城市群空间联系分析

Analysis on the spatial relation of Beibu Bay urban agglomerations

采用城市流和城市相互作用强度模型对北部湾城市群空间联系进行度量,结果表明,北部湾城市群城市流强度整体偏小,城市对外服务功能较弱;城市流强度南宁最强,钦州、玉林、防城港次之,北海、崇左最小;南宁、钦州在北部湾城市群中发挥着重要作用,是城市群中最为重要的两个节点;城市空间联系不紧密,城市群仍处于初期发育阶段.根据上述结论,提出了加强北部湾城市群空间联系的建议.

The spatial contact of Beibu Bay urban agglomerations is measured by means of urban flow and intensity of urban interaction models . T he results indicate that the intensity of urban flow of Beibu Bay urban agglomerations is overall small , the outward service function of cities is weaker ;the intensity of urban flow of Nanning is the strongest , Qin Zhou , Yu Lin and Fang Cheng Gang take second place , the intensity of urban flow of Beihai and Chongzuo is minimal ;Nanning and Qin Zhou play an important role in Beibu Bay urban agglomerations , and they are two most important nodes in urban agglomerations ;urban spatial interaction is general , urban agglomerations is still at an early development stage . Finally , According to the above-mentioned conclusion , some suggestion are put forward to strengthen the spatial contact of Beibu Bay urban agglomerations .
