基于百度指数和引力模型的城市网络对比——以京津冀城市群为例
发布时间：2018-07-31 17:22
【摘要】：城市网络已经成为分析城市群内部城市之间的相互作用及其流动方式的重要方法.利用传统地理学引力模型法以及信息时代的百度指数法绘制城市网络,划分网络中的主干结构,并对比分析京津冀城市群中的网络结构特征和城市层级分布.研究发现:百度指数网络的主干结构呈现出以北京为中心的伞型模式,引力模型网络则呈现出以北京、天津为双核心的发散模式;引力模型网络相对稳定,随时间的增长变化较小,而百度指数网络对时间和城市功能定位的响应更加明显;根据各城市在不同模型中的总联系值占比差,将城市群内城市分为虚拟空间指向型城市(石家庄、保定、秦皇岛、张家口、承德),实体空间指向型城市(天津、唐山、廊坊、沧州),以及虚实均衡型城市(北京、邯郸、邢台、衡水).
[Abstract]:Urban network has become an important method to analyze the interaction and flow among cities in urban agglomeration. By using the traditional gravity model of geography and the Baidu index method in the information age, the urban network is drawn, the main structure of the network is divided, and the network structure and the urban level distribution in the Beijing-Tianjin-Hebei urban agglomeration are compared and analyzed. It is found that the trunk structure of Baidu index network presents an umbrella pattern centered on Beijing, while the gravity model network presents a divergent pattern with Beijing and Tianjin as the core, and the gravity model network is relatively stable. The response of Baidu index network to time and urban function positioning is more obvious, according to the difference of the total contact value of each city in different models, the Baidu index network has a more obvious response to the location of time and urban function, according to the difference of the total contact value of each city in different models. The cities in the urban agglomeration are divided into virtual space oriented cities (Shijiazhuang, Baoding, Qinhuangdao, Zhangjiakou, Chengde), solid space oriented cities (Tianjin, Tangshan, Langfang, Cangzhou), and virtual and real balanced cities (Beijing, Handan, Handan). Xingtai, Hengshui).
