| 中文摘要: |
| 基于统计学和GIS方法对京津冀地区2013—2017年间空气质量指数（AQI）分布情况及影响因素进行分析，探究城市发展对空气质量的影响。结果表明：京津冀地区空气质量大体趋势由北向南逐渐恶化，可宏观对比5年的变化，污染程度逐年减弱；PM10为首要污染物所占的天数比例最高，O3为首要污染物所占的天数比例逐年增加；气温、风速与AQI呈负相关，而相对湿度、气压与AQI不同地区正负关系不同；空气质量与经济增长的环境库兹涅茨曲线为倒N型。 |

| Based on statistics and GIS method, this paper mainly studied the influence factors of urban development on air quality by the distribution of air quality index(AQI) during 2013—2017. The results showed that the air quality in Beijing Tianjin Hebei region became worse from north to south. But the pollution level decreased yearly in the past five years. The days of PM10 as the chief pollutant were the most, the days of O3 as the chief pollutant increased year by year. Air temperature and wind speed were negative correlated with AQI, while relative humidity and air pressure were positive or negative correlated with AQI in different regions. The Environmental Kuznets Curve(EKC) of air quality and economic growth presented inverted N type. |
