Abstract

In view of the air quality situation in China, the air qualities of 16 cities of Anhui Province where monito-ring stations are located were analyzed. The temporal and spatial distributions of air quality of Anhui Province are preliminarily obtained based on monitoring data of air quality index from January to June in 2015 by using ArcGIS and SigmaPlot. Results show that 1) air quality in each city of Anhui Province improves with time; 2) the air quality of cities in southern Anhui is better than that in northern cities, worst in Hefei and Huaibei and best in Huangshan and Chizhou. The development of urban industry is an important factor which affects the air quality; 3) the AQI (air quality index) of each city fluctuates to different extents in different months. The value range of AQI concentrates in months of good air quality, and gets discrete in months of poor air quality.

Key words
