【摘要】：基于職能與區(qū)位二元視角,構(gòu)建綜合評價指標體系,對2014年中國地級以上城市的門戶性、門戶等級體系、門戶群以及門戶城市的空間結(jié)構(gòu)與意象進行研究,結(jié)果表明:1中國城市門戶性在地帶性尺度上呈"東中西"三級遞減空間格局,東部地區(qū)門戶城市空間集群趨勢明顯,中部、西部地區(qū)缺乏明顯的高值集群。2中國門戶城市劃分為4個等級,高等級門戶沿海、沿江、沿邊指向性明顯,低等級門戶廣泛分布于中、西部內(nèi)陸地區(qū)。3中國門戶城市可劃分為遼東半島、京津秦唐、山東半島、長江三角洲、海峽西岸和珠江三角洲六大門戶群,六大門戶群的腹地范圍差異較大且區(qū)域分工明顯。
[Abstract]:Based on the dual perspective of function and location, this paper constructs a comprehensive evaluation index system, and studies the spatial structure and image of the cities above the prefecture level in China in 2014, including the door-to-door system, the portal class system, the portal cluster and the spatial structure and image of the portal city. The results show that: (1) on the zonal scale, the urban door size of China shows a three-level decline pattern of "East and West", and the trend of spatial cluster of portal cities in the eastern part of China is obvious, and in the middle part, There is a lack of obvious high-value clusters in the western region. (2) China's portal cities are divided into four levels, high-grade portals along the coast, along the river and along the edge with obvious directionality, and low-grade portals are widely distributed in the middle. 3 the gateway cities of China can be divided into six main portals: Liaodong Peninsula, Beijing, Tianjin, Qin and Tang, Shandong Peninsula, Yangtze River Delta, West Bank of Taiwan Strait and Pearl River Delta, and the hinterland of the six portals is different and regional division of labor is obvious.
