基于GIS的北京市机动车污染数据库的开发和应用

Development and Applications of Database for Beijing Vehicular Emissions Based on GIS

利用 GIS技术建立机动车污染数据库 ,能动态、直观地反映机动车污染的时空分布规律 ,为机动车污染控制研究提供强有力的工具 .本研究以 Arc View为主要的 GIS开发工具 ,通过属性数据和空间数据的链接 ,实现了北京市机动车污染数据库的地图化表现、动态查询、基本空间分析等功能 ,从而为机动车污染数据库提供了技术支持 .利用该系统 ,可以对北京市机动车污染物的排放、浓度和分担率的空间分布规律进行 GIS实例分析 .

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.
