Abstract: An e-map based air quality reporting system was developed with MapX and VB in order to intuitively report the quality of air. This system consists of purity gas analyzer, communication network and monitoring center. The system can display the quality level of any polluted area and the air composition of any location. Pollution consistency is computed with Gaussian model for the point spread and differential algorithm. The system provides other functions, such as location composition query, region composition query. Experiment results show that the system can meet the requirements of air quality monitoring. 

摘要： 为直观地报告大气质量,开发了MapX和VB集成的基于电子地图的大气质量报告系统。本系统由
空气质量检测仪、通信网络、监视中心组成。该系统可以显示由多个污染点源引起的污染区域空气质量等级和任意
点的空气含量指标。污染物的浓度算法采用了点源扩散高斯模型和邻域差分等算法。同时系统还提供了定点指标
查询、区域指标查询和统计等功能。实验结果表明,系统能够满足实际需要。
