Urban Air Pollution Study Based on GIS

This paper proposes a research framework for studying urban air pollution. The framework generalizes the comprehensive thinking and process of urban air pollution research from a GIS-based perspective and pays more attention to the spatial distribution of air pollution. It includes three sections in sequence of data acquisition, model running and result applications. The authors utilize spatial data management and analysis that GIS provides to organize the data and implement urban air pollution research methods involved in the framework. Through these GIS-based improvements and implementations, urban air pollution spatial distribution trends are much better represented and learned. The interrelationships between the involved methods are strengthened.
