城市化地区实体与流空间演变及高质量发展路径分析

Evolution of urbanized area’s entities and flow space towards high-quality development path in China

生态文明和美丽中国建设进入关键期,城市化地区是美丽中国地理图景的重要空间载体,人地关系矛盾最为突出,也是美丽中国建设难点。聚焦城市化地区的实体地域,基于大数据技术方法,厘清中国城市不透水面的时空分布与分组演化特征,分析流空间视角下城市体系流动网络的结构特征,提出对新时期促进城市化地区高质量发展途径的初步思考与政策建议。以人为核心建设人民城市、分级分类引导城市多样化发展、绿色韧性健康的城市可持续模式、科技创新功能与智慧城市建设、常态化开展城市体检工作等,支撑中国式城市化现代化与美丽中国目标实现。

The eco-environmental conservation and Beautiful China have entered the critical phase.Urbanized areas serve as important spatial carriers in the Beautiful China initiative scenarios,but the most prominent challenges in human-environment relationship and difficult points in building Beautiful China.This study focuses on the physical urban area,and utilizing big data technology to reexamine the spatiotemporal distribution and grouped evolution characteristics of impervious surface in cities,as well as the structural features of urban flow networks from space of flows.Moreover,preliminary thoughts and policy recommendations are provided for promoting high-quality development in urbanized areas of the new era.More efforts should be made in promoting the people-oriented urban construction,introducing the classified guidance on the diversified development path of cities,establishing green,resilient,and healthy urban sustainable models,strengthening technological innovation in smart city,implementing regular urban physical examination,etc.,to achieve the realization for Chinese path to urbanization and modernization and Beautiful China initiative.
