“十三五”期间莆田市环境空气质量变化分析

Analysis on the Change of Ambient Air Quality in Putian City during the "13th Five-Year Plan" Period

近年来,莆田市经济总量不断扩大,城市人口持续增加,资源和环境的制约日趋突出,环境压力不断增加。本文以莆田市“十三五”期间4个国控监测站点的大气自动监测数据为基础,分别从主要污染物浓度、环境空气质量指数、环境空气质量达标率等方面入手,分析莆田市空气质量状况及污染特征,然后提出建议,以改善区域环境空气质量。

In recent years, the total economic volume of Putian City has been expanding, the urban population has been increasing, the constraints of resources and environment have become increasingly prominent, and the environmental pressure has been increasing. Based on the atmospheric automatic monitoring data of four state-controlled monitoring stations in Putian City during the "13th Five-Year Plan" period, this paper analyzes the air quality status and pollution characteristics of Putian City from the aspects of main pollutant concentration, ambient air quality index and ambient air quality compliance rate, and then puts forward suggestions to improve the regional ambient air quality.
