發(fā)布時(shí)間:2018-07-31 17:22
【摘要】:城市網(wǎng)絡(luò)已經(jīng)成為分析城市群內(nèi)部城市之間的相互作用及其流動(dòng)方式的重要方法.利用傳統(tǒng)地理學(xué)引力模型法以及信息時(shí)代的百度指數(shù)法繪制城市網(wǎng)絡(luò),劃分網(wǎng)絡(luò)中的主干結(jié)構(gòu),并對(duì)比分析京津冀城市群中的網(wǎng)絡(luò)結(jié)構(gòu)特征和城市層級(jí)分布.研究發(fā)現(xiàn):百度指數(shù)網(wǎng)絡(luò)的主干結(jié)構(gòu)呈現(xiàn)出以北京為中心的傘型模式,引力模型網(wǎng)絡(luò)則呈現(xiàn)出以北京、天津?yàn)殡p核心的發(fā)散模式;引力模型網(wǎng)絡(luò)相對(duì)穩(wěn)定,隨時(shí)間的增長(zhǎng)變化較小,而百度指數(shù)網(wǎng)絡(luò)對(duì)時(shí)間和城市功能定位的響應(yīng)更加明顯;根據(jù)各城市在不同模型中的總聯(lián)系值占比差,將城市群內(nèi)城市分為虛擬空間指向型城市(石家莊、保定、秦皇島、張家口、承德),實(shí)體空間指向型城市(天津、唐山、廊坊、滄州),以及虛實(shí)均衡型城市(北京、邯鄲、邢臺(tái)、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).
