摘要
本文利用网络爬虫技术,抓取2022年7月成都市景点兴趣点(POI)数据,采用平均最近邻指数、核密度估计、区位熵等方法,研究成都市景点POI的空间分布特征。在此基础上,对成都市旅游业发展的相关影响因素进行分析。研究表明,成都市旅游资源空间聚集效果显著,形成中心城区显著集聚、多中心发展的空间格局。各类型景点POI集聚程度存在差异,集聚程度由低到高的景点依次为宗教文化景观、风景名胜、其他、城市广场、公园。空间分布格局的形成受自然因素和社会经济因素共同影响,人口密度、景点密度、区域经济水平、交通条件和资源优势是影响全市旅游业收入的正向因子。
The web crawler technology has been used to capture the Point of Interest(POI)data of tourist attractions in Chengdu in July 2022,and the spatial distribution characteristics of Chengdu attractions POI have been discussed by means of average nearest neighbor analysis,kernel density estimation,location entropy and other methods.On this basis,the relevant influencing factors of tourism development in Chengdu are analyzed.The results show that the spatial agglomeration effect of tourism resources in Chengdu is remarkable,forming a spatial pattern of significant agglomeration of central city and multi-center development.The POI agglomeration degree of all types of attraction is different,ranking from low to high that religion and culture attractions,scenic spot,other spots,city squares and parks.The formation of spatial distribution pattern is influenced by both natural factors and social and economic factors,and population density,attraction density,regional economic level,traffic condition and resource advantages are positive factors affecting tourism income of the city.
