摘　　要：反思城市新区服务业空间布局的合理性,探讨城市新区规划中功能区的产业定位与服务业空间布局的匹配性,对优化城市新区服务业空间格局,促进服务经济高质量发展意义重大。基于服务业POI数据,利用DBSCAN算法对广州南沙新区服务业整体和分行业空间布局进行全面系统地聚类研究。结果表明:(1)整体上,服务业聚类簇的空间等级分布特征明显,呈现“124”空间布局体系;服务业集聚于功能区和跨功能区共存;噪声点星状分布、孤立零散,局部呈现出未来服务业集聚的潜在区域;空间邻近效应和市场需求导向作用致使服务业空间极化现象显著。(2)分行业上,明珠湾起步区区块和蕉门河中心区区块已成为南沙新区大部分行业的重要空间节点分布区,但部分服务行业的空间节点分布差异明显;存在行业空间节点和功能区的产业定位匹配吻合与错位不符共存现象。最后,提出推动功能区产业结构合理化的发展思路,以期为广州南沙新区服务业空间布局改善和服务经济高质量发展提供参考。It is significant to review the rationality of the spatial layout of the service industry in new urban areas and to explore the matching between the industrial positioning of the functional areas and the spatial layout of the service industry when planning new areas,so as to optimize the spatial pattern of the service industry in the new areas and advance the service economy.Based on the POI data of a service industry,this paper uses the DBSCAN algorithm to conduct a comprehensive and systematic clustering study on the spatial layout of the service industry both on the whole and by subdivision in Nansha New District,Guangzhou.The result shows that generally the spatial distribution characteristics of the clusters of the service industry is obvious,presenting a"124"spatial distribution structure.Service industries are clustered in functional areas and coexist with cross-functional areas.The noise points are sporadic,isolated and scattered,showing the potential agglomeration areas of future service industry.Spatial proximity effect and market demand-oriented effect lead to a significant spatial polarization of the service industry.By industry sectors,the Mingzhu Bay Startup Block and Jiaomen River Central Block have become important spatial node areas for most industries in Nansha New District.However there are significant differences in spatial node distribution for certain service industries.Both match and mismatch between spatial nodes of industries and industrial positioning of function areas exist simultaneously.Finally,the paper suggest to develop a rational industrial structure in the functional zone,with a view to providing advice for the improvement of spatial layout of the service industries and high-quality development of the service economy in Nansha New District in the City of Guangzhou.
