基于 POI 数据的珠海城市中心功能聚集度对比分析系统设计与实现摘 要信息技术的发展与普及为城市研究带来了前所未有的机遇，在地理信息系统中通过海量 POI 数据对城市进行研究，可以使城市治理更加科学化、精细化、智能化。作为粤港澳大湾区的重要组成部分，近年来珠海的发展迎来了难得的黄金时期；而城市的发展离不开对于城市准确的定位与战略性的规划。论文通过 Python 技术，对 POI（兴趣点）数据进行爬取；然后借助 R 语言结合地图信息编辑开发软件 ArcGIS，对获取到的 POI 数据进行建模分析；最后使用 Java 和前端框架构建展示系统，把已分析的数据进行上传、解析与对比展示。结论显示珠海城市综合中心分布可以概括成“一核、两翼、多片区”的形态，虽具体情况不同使不同类型的 POI 热力分布略有出入，但总体仍基本符合上述结论。关键词：POI；大数据；珠海；城市中心；城市研究；地理信息；空间分布Design and Implementation of Comparative Analysis System for Functional Aggregation of Zhuhai City Center Based on POI DataAbstractThe development and popularization of information technology has brought unprecedented opportunities to urban research. Researching cities through massive POI data in geographic information systems can make urban governance more scientific, refined, and intelligent. As an important part of the Guangdong-Hong Kong-Macao Greater Bay Area, the development of Zhuhai in recent years has ushered in a rare golden period; and accurate positioning and strategic planning are essential in the development of the city.The paper uses Python to crawl POI (points of interest) data; then, using R language combined with map information editing and development software ArcGIS to model and analyze the obtained POI data; finally, using Java and front-end framework to build the display system to upload, parse, compare and display the analyzed data.The conclusion shows that the distribution of the comprehensive center of Zhuhai City can be summarized into...
