基于多源大数据的宁波市城市公园供需服务特征分析
Analysis of supply and demand service characteristics of urban parks in Ningbo City based on multi-source big data
摘要
Abstract
Urban parks are ideal places for urban residents to conduct leisure activities,and the balance between their demand and supply plays an important role in improving the health level of all people and building a high-quality public service system for national fitness.Taking urban parks in Ningbo City as an example,this paper employed multi-source big data such as cell phone signaling data and area of interest(AOI)of urban parks,analyzed the visitor flow of the urban park in terms of the number of service users and service hours,quantified the degree of demand for the urban park by service demand,and determined the level of supply of the urban park by accessibility,thus completing the classification and analysis of the supply and demand service characteristics of urban parks in Ningbo City.In addition,it put forward targeted optimization suggestions.The results show that the service demand for urban parks in Ningbo City is mainly concentrated around the city or county-level center.Its urban areas have a relatively higher level of supply,and most urban residents are able to reach the parks conveniently.Overall,urban parks in Ningbo City show a relative balance between supply and demand.Different supply and demand service characteristics show a more obvious hierarchical distribution around each county-level or district-level center.关键词
