摘要: 在大数据引领的新型规划背景下，认知城市人群的时空活动特征进而剖析城市发展的内在问题正成为新的研究趋势。既有关于城市人群活动的研究主要集中于经济发达城市内人群迁移规律对城市结构的影响，而对于生态脆弱地区人群迁移特征对环境的影响研究较少，未能发掘出生态环境制约下城市人群活动的特殊性。因此，选取贵州省黔西南州兴义市这一典型喀斯特地貌区为研究对象，基于LBS大数据测度分析兴义市人群的聚散特征，探究脆弱生态约束下城市的内在动态结构，对于发掘我国西南地区城市在特殊发展背景下的特色问题以及实现人本规划具有重要意义。
Abstract: Under the background of new-type planning led by big data, it is becoming a new research trend to analyze the characteristics of time and space features of urban population and then figure out the internal problems of urban development. However, current researches mainly focus on the impacts of population migration on the urban structure in economically developed cities, while those on the ecological environment in ecologically fragile areas are less concerned. This leads to the inability to discover the particularity of urban population activities under the constraints of the ecological environment. Therefore, this paper takes a typical Karst area of Xingyi City in southwest Guizhou Autonomous Prefecture as the research object. Based on the LBS big data measurement and the analysis of the crowd-scattering characteristics of Xingyi City, this paper explores the intrinsic dynamic structure of the city under ecological constraints, which are of great significance for exploring the characteristics of southwestern cities in China under their unique development backgrounds and for realizing the humanistic planning.
