摘要
空气质量的好坏直接影响到人体的健康状况,空气质量指数(AQI)已成为影响人们生活的重要因子之一。本文以2016年全年的中原城市群30个城市的AQI监测数据为基础,运用散点图、柱形图、普通克里金法和反距离权重法等研究其时空分布特征。中原城市群AQI数值整体存在明显的季节变化趋势,冬季最高,春秋季次之,夏季最低。8月份AQI数值均在100以下,是零污染月;1月和12月AQI数值均在100以上,是完全污染月,且有不少区域为重度污染。AQI数值区域性分布明显,呈现出以郑州、邢台、聊城及南阳为中心的空气质量较差的高值集聚区域和以蚌埠、亳州、阜阳、淮北、宿州、信阳、晋城及运城为中心的空气质量较好的低值集聚区域。
Environmental quality is directly affecting the health of the human body,environmental quality index( AQI) has become one of the important factors affecting people's lives. Based on the AQI monitoring data of 30 cities in the Central Plains region in 2016,the spatial and temporal distribution characteristics are studied by using data analysis methods such as scatter chart,column chart,ordinary kriging method and inverse distance weight method. The results show that the Central Plains city group as a whole there is a clear seasonal change. AQI numerical performance is the highest in winter,followed by spring and autumn,the lowest in summer.In August,the AQI value was below 100,and it was zero pollution month. The number of AQI in January and December was above100,it was completely polluted month,and many areas were seriously polluted. The AQI value is obviously regional distribution,which presents a high value agglomeration area with low air quality centered on Zhengzhou,Xingtai,Liaocheng and Nanyang and of low value of air quality in the center of Bengbu,Bozhou,Fuyang,Huaibei,Suzhou,Xinyang,Jincheng and Yuncheng city.
