摘要
构建中心—门户综合评价系统,对云南省地级、县级两种尺度上中心与门户进行空间识别,刻画"一带一路"背景下的对外开放布局与空间意象.结果表明:昆明是门户型中心城市,中心城市多为地方行政中心,在空间上集中于滇中地区,门户城市多为拥有高等级口岸、机场、港口、车站的窗口地区,多数中心存在尺度上的继承性,而门户存在尺度上的错位性;云南省的中心—门户组合形成了"东密西疏、东西独立、定非互补"的空间格局,县级尺度是对地级尺度的深化和补充,昆明在两种尺度和两种对外开放形式上都表现出显著的携领作用;现已形成9组双核结构,其中,曲靖—昆明及其之间的昆曲快速通道是云南省的经济地理横轴,昆明(主城区)—红河(河口县)、大理(市)—德宏(瑞丽市)是推动昆明—河内、昆明—皎漂两条对外经济走廊建设的核心,保山(腾冲市)、西双版纳(勐腊县)应当提升建设层次和力度.
Based on construction of comprehensive evaluation system about centrality and gateway property,this paper carried out spatial identification of centers and gateways and conducted research in opening-up spatial structure and imagery on prefecture and county scales in Yunnan Province in the context of the Belt and Road.The main conclusions of this paper are listed as follows.Firstly,Kunming is gateway-based central city.Most central cities are local administrative centers and amassing in middle Yunnan Province spatially.Most gateway cities possess high-level ports,airports,harbors and stations.There is inheritance existing on scale in most central cities,while there is dislocation existing on scale in most gateway cities.Secondly,spatial pattern of center-gateway combination in Yunnan Province can be described as follows,"dense in the east and sparse in the west""east-west independence"and"directed and undirected opening-up complementing each other".County scale is deepening and supplementing to prefecture scale.Kunming shows prominent leading role on both scales and both types of opening-up.Thirdly,there are 9 groups of dual-nuclei structures formed on the two scales in Yunnan Province,among which,Qujing-Kunming with the quick path of Kunming-Qujing line is the cross axis of economic geography in Yunnan Province;Kunming(main city)-Honghe(Hekou county),Dali(city)-Dehong(Ruili city)are the cores which promote construction of two external economic corridors of Kunming-Hanoi and Kunming-Kyaukpyu;Baoshan(Tengchong city)and Xishuangbanna(Mengla county)both should improve their construction level and strength.
