针对我国环境空气质量现状及研究热点区域,为了解安徽省空气质量状况,对安徽省16个覆盖空气质量监测站点的地级市的空气质量进行分析。根据2015年1—6月份期间的空气质量指数监测数据,利用ArcGIS和SigmaPlot等分析统计软件,初步获得安徽省环境空气质量的时空分布格局。结果表明:研究期间安徽省各地级市的空气质量整体呈随时间而提高的趋势;省内空气质量存在一定程度的南北空间差异,即南部城市的空气质量优于北部城市,且以合肥、淮北空气质量为最差,以黄山、池州空气质量为最优,城市工业产业发展状况是影响其空气质量的重要因子之一;各市AQI存在不同程度的月内波动性,空气质量越好的月份AQI的值域分布越集中,空气质量越差的月份AQI的值域分布越离散。
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.
