【摘要】：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Arc GIS和Sigma Plot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 current situation and hot spots of environmental air quality in China, in order to understand the air quality status of Anhui Province, the air quality of 16 cities covering the air quality monitoring stations in Anhui was analyzed. Based on the monitoring data of air quality index from 1 to June in 2015, the spatial and temporal distribution pattern of ambient air quality in Anhui province was preliminarily obtained by using Arc GIS and Sigma Plot. The results showed that: during the study period in Anhui province around the city's overall air quality was increased with the time trend; there is a certain degree of difference between North and South space in the southern city of air quality, air quality is better than the northern city of Hefei, Huaibei, and the air quality is the worst, in Mount Huangshan, Chizhou air quality is the best. The development status of the industrial city is one of the important factors affecting the air quality in the city; AQI existence of different degrees of fluctuation of the distribution range of AQI months, in better air quality more concentrated, AQI in air quality worse the more discrete distribution range.
