基于POI数据的西安市餐饮业空间分布特征分析

Analysis on Spatial Distribution Characteristics of Catering Industry Based on POI Data

在大数据背景下,结合空间分析和文本分析,对西安市餐饮业进行显性和隐性问题的挖掘和归纳,借助互联网爬虫工具和百度API平台,运用POI数据定性定量分析相结合的方法构建出西安市餐饮业的整体特征。通过python编写爬虫代码,以西安市餐饮业商户为研究对象,爬取了XX网站西安地区的餐饮业商户数据,利用大数据进行商户信息研究,分析了空间分布特征。研究发现,城市餐饮业商户主要集中于主城区,各中心内部呈现出核密度圈层递减特征。

Under the background of big data, combined with spatial analysis and text analysis, the explicit and implicit problems of Xi’an catering industry are excavated and summarized. With the help of Internet crawler tools and Baidu API platform, qualitative and quantitative analysis of POI data is used to construct the overall characteristics of the catering industry in Xi’an. The crawler code was written through python. Taking Xi’an catering business merchants as the research object, it crawled the data of catering business merchants in Xi’an area on XX website, and used big data to study the merchant information, and to analyze the spatial distribution characteristics.
