摘要随着经济的日益增长,环境问题也变得越来越严重。厦门市是福建省的一个重要城市,并且也是旅游城市,风景十分优美。研究厦门市的空气质量指数与气象条件,能够更好得为改善空气质量提供依据,并作相关的准备,为厦门市创造更美好的蓝天。本文利用2015年厦门市夏季空气质量资料和气象资料,根据厦门市夏季的四个空气质量监测站点的空气质量数据,研究空气质量指数的时空分布特征与其气象条件的关系。结果表明: 厦门市空气质量优良率为99。18%,其中优级率55。34%,主要的空气污染物为PM10和PM2。5 。NO2和SO2月平均浓度变化不明显,但最高平均浓度都在5月份。O3平均浓度呈逐月上升趋势,SO2的平均浓度则在一天中呈下降趋势;PM10、CO浓度的月变化趋势基本相同。各污染物在不同监测点浓度也有较大差异,并且气象条件也对污染物浓度有着一定的影响。2015 年相对湿度平均值和AQI平均值变化趋势每月呈正相关关系,但是气温平均值和AQI平均值71852
变化却呈负相关关系。

Temporal and Spatial Distributions Characteristics of Air Quality Index and Meteorological Conditions in Xiamen
Abstract
With the growing economy, environment problems become more and more serious。 Xiamen is an important city in Fujian province and it is also a tourist city where the scenery is very beautiful。 The research of Xiamen city air quality index and meteorological conditions can provide a better basis for the improvement of the air quality and do preparations to create a better blue sky relatively。 Using the summer air quality data and meteorological data of Xiamen city in 2015 and air quality data of four air quality monitoring stations can analyze the spatial and temporal distributions of air quality in Xiamen city and its relationship with meteorological condition。 Analysis results show that the probabilities of excellent and good grades for air quality were up to 99。18%, the excellent rate was 55。34% and the main air pollutants are PM10 and PM2。5。 The monthly average concentrations of NO2 and SO2 changed little while the monthly average concentrations were highest in May。 The monthly average concentrations of O3 showed an increasing trend month by month while the average concentrations of SO2 in the day showed a downward trend。 The monthly changing trends of the concentrations of PM10 and CO were similar。 The concentrations of different pollutants in different monitoring points are also different and meteorological conditions also have a certain impact on the concentrations of pollutants。 The monthly average value of relative humidity has a positive correlation with the change trend of the air quality index, but the air quality index was negatively correlated with temperature monthly。
