Development and Applications of Database for Beijing Vehicular Emissions Based on GIS
基于GIS的北京市机动车污染数据库的开发和应用

The database for vehicular emissions based on GIS technology,which can illustrate the spatial distribution of emission dynamically and visually,can provide the powerful tool for the study on vehicular emissions in emissions control strategy.Using ArcView GIS as the main development tool of the Database for Beijing Vehicular Emissions,authors joined spatial and attribute data,and achieved the functions of data operation,graphical expression,dynamic query,and basic spatial analysis.This system helped us to make the study on the regularity of vehicular emission distribution of emissions intensity,concentration,and partition rate in Beijing.
