摘　　要：为了评估宝鸡市大气污染防治情况,针对性分析城市AQI(空气质量指数)年际变化特征及“采暖期”重点企业对市区大气污染“贡献度”。利用Python技术获取宝鸡市区8个空气质量国控站点和11家大气环境国控重点排污企业实时监测数据,采用ArcGIS软件开展时空差异分析。结果表明:2016年-2019年宝鸡市区空气质量有所好转,PM_(10)、PM_(2.5)是宝鸡市大气污染的主要因子;宝鸡市区大气污染呈现自东向西递减的趋势,城区西部空气质量优于城区东部;对大气污染“贡献度”最大的企业为热电厂与水泥厂,贡献了高浓度的SO_(2)与NO_(2)。In order to evaluate the prevention and control of air pollution in Baoji city,the annual variation characteristics of urban AQI(Air Quality Index)and Contribution Degree of key enterprises to urban air pollution during heating period were analyzed.Python technology was used to obtain real-time monitoring data of 8 state-controlled air quality stations and 11 key polluter under state control of atmospheric environment in Baoji urban area,ArcGIS was used to analyze the spatio-temporal differences.The results showed that:Air quality of urban area improved from 2016 to 2019,PM_(10) and PM_(2.5) were the main factors of air pollution.Air pollution in urban area decreased from east to west,the west was better than that in the east.Thermal power plants and cement plants had the largest Contribution Degree to air pollution,with high concentrations of SO_(2) and NO_(2).
