摘要
以武汉青山区(含化工区)为例,采用定性定量相结合的方式,测度物质和社会空间联系,对大都市穿孔式收缩空间联系展开探讨,并验证其“孤岛效应”的存在。结果表明:1)青山区存在路网可达性低和交通设施不均衡分布等问题,内外物质空间联系相对薄弱,是导致“孤岛效应”产生的重要因素;2)青山区存在基础设施弱化且不均衡分布、对外吸引力差及政策层面独立发展等特征,内外社会空间联系相对不足。上述因素间相互影响,共同推动青山区“孤岛效应”的产生;3)因大都市穿孔式收缩常伴随着“孤岛效应”出现,各城市在后续发展过程中应加快推进交通网络连通和公共空间建设,规避空间联系层面的孤立和封闭。同时应重视不均衡发展问题,加快推动区域间合作及人才引进等相关政策落实。
As urban development progresses,the complex phenomenon of city shrinkage increases.Perforated shrinkage is a leading pattern within Chinese cities.In this study,the Qingshan District in Wuhan(including its chemical industrial area)is considered as a representative case of a large metropolitan area experiencing perforated shrinkage.Through the use of methods such as spatial syntax,Point Of Interest(POI)analysis,and word frequency analysis,the study examines material and social spatial connections to verify the existence of an"island effect".The following results were obtained:1)Analysis of the topological relationships within the Wuhan metropolitan development area and the interior regions of the Qingshan District reveals that Qingshan has low global and local integration values as well as choice metrics,indicating issues related to roadway accessibility and uneven distribution of transportation facilities.This leads to weak internal and external material spatial connections.Additional kernel density analysis of public facility POIs indicates poor and uneven infrastructure distribution in Qingshan.Additionally,questionnaire surveys and word frequency analysis suggest deficiencies in the area's external attractiveness and independent development at the policy level.These factors interact and contribute collectively to the island effect within Qingshan District.2)Recognizing the similarities in the developmental background and policy frameworks between other domestic cities experiencing perforated shrinkage and the Qingshan District,this study infers that the island effect is a characteristic of metropolitan areas showing perforated shrinkage and is closely tied to institutional factors within Chinese urban areas.3)The phenomenon of metropolitan perforated shrinkage and spatial connections have an interactive relationship,leading to the emergence of regional island effects.These island effects underscore the importance of coordinated internal development within the region,providing novel perspectives for managing ur
