摘　　要：公共服务配套设施的布局规划是新型城镇化建设的重要内容,公共厕所作为城市文明的“窗口”,其合理布局对提升城市质量和打造宜居环境至关重要。以珠海市19个街道办为例,基于百度大数据,分析流动人群的分布情况,获得公共厕所的出行人群密度分布图,进而结合城市道路的网络分析结果,获得公厕的服务范围分布图,并计算得到公厕的空间覆盖率和人口覆盖率,评价各街道办公共厕所的空间布局合理性,并提出了相关建议。结果表明,珠海市公共厕所布局不太合理,尤其是西区各街道办,需要进一步优化,才能满足未来的发展要求。The layout of infrastructures for public services is one of the important components of the new urbanization development.Public toilets,as the"window"of urban civilization,help improve urbanization quality and create a livable environment.Taking 19 sub-districts of Zhuhai city as an example,we explore the spatial distribution of crowd movement based on Baidu big data.We also obtain the distribution map of public toilets.The service area of each public toilet is derived based on urban road network analysis.Then the service area and service population of public toilets are calculated,and the rationality of spatial layout of public toilets is evaluated.Suggestions are given based on the above analyses.Results show that the spatial layout of public toilets of Zhuhai city is not reasonable,especially for sub-districts of the western district.Layout optimization is necessary to meet future development requirements.
