中文摘要:
      随着我国经济的快速发展,不可避免的伴生了一系列环境恶化问题。为了分析和掌握近年来山东省大气质量的变化状况,本文充分利用山东省2015—2018年的空气质量监测数据,通过时序变化分析、空间自相关分析、大气质量重心迁移分析等方法,对山东省17个地市的空气质量指数(AQI)进行了年际序列变化及季节性变化特征分析,并通过建立的空间自相关和重心迁移模型,探索了17个地市AQI的空间聚集特征及重心迁移发展规律。研究结果表明:山东省各地市的AQI在年际尺度上是逐年降低,西部和中南部等地区空气质量较差,空气质量呈现出冬夏分明的季节性变化,而沿海地区的城市空气质量整体较佳,季节性规律表现不太明显;各地市AQI的Moran's I(莫兰指数)逐年降低,各地市空气质量空间自相关性呈逐年减弱的聚集态势;重心迁移分析表明山东省城市群近年来的AQI重心呈现出自西向东微弱偏移的趋势。
英文摘要:
      With the rapid development of China's economy, a series of environmental degradation problems are inevitables. In order to analyze and master the changes in the atmospheric quality of Shandong Province in recent years, this article makes full use of the air quality monitoring data of Shandong Province from 2015 to 2018, by means of time series change analysis, spatial autocorrelation analysis, and atmospheric mass center of gravity transfer analysis, the air quality index (AQI) of 17 cities in Shandong Province was analyzed for interannual sequence changes and seasonal changes, and by the established of spatial autocorrelation and center of gravity migration model, the spatial aggregation characteristics and the development rule of center of gravity migration of AQI in 17 cities were explored. The results show that the AQI of cities in Shandong Province is decreasing year by year, and the air quality in the western and central and southern regions is poor, air quality shows a seasonal change in winter and summer, the overall urban air quality in coastal areas is better, and the seasonal pattern is not obvious. The Moran’s I (Molran Index) of AQI in various cities decreases year by year, and the spatial autocorrelation of air quality in various cities is showing a trend of weakening year by year. The gravity center migration analysis shows that the AQI gravity center of Shandong urban agglomeration in recent years has shown a tendency to shift slightly from west to east.
