摘要
同城化是都市圈发展的重要目标,定量探究都市圈同城化空间特征,对都市圈实现协调发展具有重要意义。以武汉都市圈为例,从空间拓展、交通、人口、经济产业、公共服务的多维视角,综合运用夜间灯光、路线规划API在内的多源数据对都市圈同城化特征进行分析。结果发现:①武汉都市圈建成区呈“一核心迅速扩张,多散点稳步拓展”的空间特征;②驾驶等时圈呈“北高南低,中心高四周低”态势,公交等时圈则出现等时圈变形和飞地,“武鄂黄黄”核心区与“一小时通勤”目标存在差距;③人口密度分布呈“中心稠密,四周分散”的不均衡格局,人口跨市流动强度呈“东高西低”的空间特征,武汉是周边城市跨市流动的首要选择;④都市圈产业专业化及高级化程度不断提高;⑤公共服务设施分布呈现“一核心,多中心”空间格局,部分设施有待优化配置。依据研究结论,从空间层面提出发展策略。
Urban integration is an important purpose for metropolitan area development,and quantifying the spatial characteristics of urban integration in metropolitan areas is critical for achieving coordinated growth.This paper used the Wuhan metropolitan area as an example,with several perspectives including population,transportation,economic and industrial,and public services.A variety of data sources were utilized,including Direction API,to optimize the analysis framework for urban integration.The results showed that:①“Rapid expansion of a core and steady expansion of multiple scattered points”was the spatial characteristics of Wuhan Metropolitan Ar-ea′s built-up area.②There were considerable isochronous deformation and isochronous enclaves on the public transport isochronous circle,and a spatial feature of“high in the north and low in the south,high in the center and low around”on the driving isochronous circle.A few locations within the“Wu-E-Huang-Huang”core still required a lengthy commute,falling short of the“one hour com-muting”target.③A“dense center and scattered surroundings”pattern was evident in the distribution of population density,while a“high in the east and low in the west”spatial characteristic was evident in the intensity of cross-city population flow.Wuhan was the primary choice for cross city mobility in surrounding cities.④The degree of industrial specialization and sophistication in metropolitan area was increasing continuously.⑤Public service facilities were distributed unevenly,with“one core,multiple centers”as the spatial pattern.Certain facilities required configuration and optimization.Finally,spatial development strategies were offered.
