普洱市思茅城区空气污染指数API时空分布特征研究

Research on the Temporal and Spatial Distribution Characteristics of API in Downtown Simao

空气污染指数(API)是一种综合反应和评价空气质量的指标,分级表征空气污染程度和空气质量状况。利用普洱市环境监测站收集的普洱市思茅城区2013—2014年度API指数,对API指数进行时间序列分析和空间分析,包括2013—2014年API的质量状况、季节变化以及比较南北市区的API值。结果表明:普洱市城区的空气状况在2013—2014年度优良,夏季的空气质量最好,春季最差;空间上存在南北差异,南市区API指数低于北市区,南市区空气质量优于北市区。

Air pollution index （API）is a comprehensive index,which reflects and evaluates air quality,that is a-dopted to represent air quality and pollution condition.On the basis of the APIs of different districts provided by Pu’er Environmental Monitoring station in Simao from 2013 to 2014,temporal and spatial analysis were conducted including quality status of API,seasonal changes,and comparison of API values between south and north in 2012. The results showed that the air condition of Simao in Pu’er was good during the study period.The air quality was the best in summer and the worst in spring.Spatially,the air quality varied in south area and north area.The south was better than the north.
