摘　　要：为揭示西南地区受城市网络牵引的空间结构重构规律,以重庆市长寿区为典型样本,采用复杂网络分析等方法,建立“三类要素、两个时点、六个模型”的技术路线,验证长寿区1985—2018年间城镇空间结构的网络演化趋势,并形成连接关系多样化、空间形态多中心化、全域可达性一体化、功能联系“去地域化”等演化特征。获得主要理论观点:(1)城镇网络是资本增值的物质手段和外在表征,是网络化“流动空间”逐步取代城镇自身“场所空间”的过程;也是资本通过时间、空间和产业三个剪刀差,构建起先发地区对后发地区、城市对乡村、不动产对其他产业利益剥削机制的过程。(2)空间规划干预应注重生态本底的保护、地域文化的承继和城乡公平的坚守,建设城乡公共利益和公共产品。(3)通过规划协调对公共产品进行有效配置,实现不同层级、不同主体间公共利益的互动和协调。In order to reveal the law of spatial structure reconstruction driven by urban networks in southwest China,the research takes Changshou District of Chongqing as a typical sample,the technical route of "three types of elements,two time points,and six models" is established by means of complex network analysis,which verifies the network evolution trend of urban spatial structure in Changshou District from 1985 to2018,and forms the evolutionary characteristics of diversified connection relationships,polycentricization of spatial morphology,global accessibility integration,and "de-regionalization " of functional connections.This paper obtains the following main theoretical views:(1) The urban network is the material means and external characterization of capital appreciation,and is the process of gradually replacing the "space of locales " of the town itself by the networked "space of flows";It is also the process of capital building a mechanism for the exploitation of the interests of the first-mover region to the late-developing area,the city to the countryside,and the real estate to other industries through the three scissors difference of time,space and industry.(2) Spatial planning intervention should pay attention to the protection of the ecological background,the inheritance of regional culture and the adherence to urban and rural fairness,so as to build urban and rural public interests and public goods.(3) Through planning and coordination,the effective allocation of public goods is realized to achieve the interaction and coordination of public interests between different levels and different subjects.
