【摘要】 近年来中国经济始终保持着高速稳健的发展态势,但是从产业结构来看,目前我国的工业化发展严重依赖于煤炭、钢铁、电力、石油化工、交通运输等高能耗、高污染的传统产业,产业结构过度集中,化石能源比例高,结构性污染十分突出。作为中国工业化和城市化的领跑者,京津冀及珠三角经济区的经济总量规模、经济发展速度、区域发展潜力都处于全国领先水平,其空气质量受到了广泛的关注。本研究利用日历视图结合点格图的可视化表达手段,对实施新空气质量标准以来的近五年（2014年-2018年）京津冀及珠三角经济区地级及以上行政区域的空气质量指数的时空分布情况进行分析。在利用日历视图可视化表达空气质量级别及各类污染物污染级别的基础上,图中还加入了表达城市之间的空间位置关系的地理参考信息。同时,通过聚类分析、相关分析和空间自相关分析的方法,探究各类污染物相关关系及各类社会经济因素对空气质量的影响,分析各区域空气污染的成因及空气质量时空分布模式的异同之处,探究京津冀及珠三角经济区的空气质量变化规律。研究结果表明,京津冀地区整体大气污染严重,自北至南污染程度加重;珠三角地区整体空气质量较好,自沿海向内陆污染加重;近五年来京津冀及珠三角地区空气质量整体波动向好,空气污染冬季>秋季>春季>夏季的季节性差异不断减弱;PM₁₀、PM_2.5污染逐年减弱,O₃污染逐年加强,二次污染对空气质量的影响不断增大;社会经济要素对城市空气质量的驱动方向及驱动强度受区域资源环境基础和社会经济发展现状的影响。空气质量可视化图为分析和理解京津冀及珠三角地区近五年空气质量时空分布模式提供了简单易懂、直观生动的方法,利用该方法对京津冀及珠三角地区各城市空气质量进行分析能够为确认各地区首要污染问题、因地制宜开展污染治理工作、提升公众的环境保护意识提供一定的理论依据。更多还原

【Abstract】 The development of economy is rapid and steady in recent years in China.Chinese economic development heavily dependent on the traditional polluting industry.Because of the high energy consumption and high pollution,the structural pollutions are more prominent than before.With the rapid economic development,environmental issues become more and more severe in China.Beijing-Tianjin-Hebei Economic Zone and the Pearl River Delta Economic Zone are two of the major economic zones in China,where the population and the economy is highly aggregated.They play necessary roles in the growth of the national economy.The two economic zones have large economic scale,strong growth potential and rapid economic development speed,representing the leading level of economic development.As the leader of industrialization and urbanization,the air condition in these economic zones received wide attention.The focus of this study was to create a map representing the spatio-temporal pattern of the air condition in the two major economic zones.Visualizing the daily condition of air quality and pollutant from 2014 to 2018 by calendar view,the map also contained geographic-referenced information which was designed to express the spatial relationship between the cities.This study focuses on the difference of the temporal and spatial distribution of air pollution between the Beijing-Tianjin-Hebei and Pearl River Delta Economic Zones,which will help to formulate pollution prevention policies on the basis of the facts.更多还原
