摘要随着我国经济社会发展和城市化水平的提高，人们越来越关注大气污染问题。 本文以 2015 年厦门市夏季 6-9 月大气颗粒物、SO2、NOX 的监测数据为依据，

结合空气污染综合指数法，对 2015 年厦门市夏季大气环境质量进行评价，分析

厦门市夏季总体污染程度，判定污染级别和指出主要的污染类型，并对大气颗粒 物时空分布特征进行研究。结果表明：厦门市夏季空气质量状况为优，相当于国 家大气质量一级标准，四个月中没有出现 API 指数大于 100 的情况。大气中主 要颗粒物为可吸入颗粒物。大气颗粒物在时间、空间污染特征具体表现为：9 月 空气状况最差，四个监测站点中洪文空气质量最好，鼓浪屿最差。污染物浓度还 受温度、湿度变化的影响，与温度、湿度呈负相关即随着温度、湿度的升高而降 低。对大气颗粒物进行污染特征研究，对厦门市预防和治理大气污染有着重要的 现实意义。69078

Characteristics of Atmospheric Particle Pollution in Summer in Xiamen

Abstract

With the gradual development of our country economy and the improvement of the urbanization, the problem of air pollution has attracted more and more attention of the people. In this paper, we base on the detection data of air pollutants such as PM10 , PM2.5, SO2, NOX of Xiamen urban district from June to September in summer in 2015. This paper evaluates the quality of Xiamen air condition in summer through air pollution index, and analyzes the level of total pollution in summer in Xiamen, then judges the degree of pollution and points out the main type of pollution. Xiamen as a representative tourist city, researching the spatial and temporal distribution of  PM10 and PM2.5 has the crucial significance. In this paper, it showed that: The air quality in summer in Xiamen was excellent, it was equivalent to first class standard by national air quality. Through four months, the air pollution index was not over 100. Inhalable particles was the main atmospheric pollutant. Atmospheric particulate matter in time and space showed that: the air condition was worst in September, the  air  condition was best in Hongwen, the air condition was worst in Gulangyu through four monitoring station. Temperature and humidity can also effect the mass concentration of the pollutant, it was a negative correlation between temperature and humidity. Analyzing the characteristics of pollutants is essential to prevent and cure for the pollution of atmospheric aerosol in Xiamen.
