文摘

Ground observations of air pollutants over Yangtze River Delta (YRD) is analyzed. Satellite-based urban form is characterized by six landscape metrics. The air quality in YRD is “moderate” for human health. Polycentric urban form is associated with high air quality. Increasing or preserving the forested areas helps mitigate the air pollutants.
