“大气十条”实施期间哈尔滨市大气污染特征研究

Air Pollution Characteristics in Harbin during Implementation of Air Pollution Control Action Plan

以2013年-2017年哈尔滨市各国控点的污染物浓度为基础数据,结合气象数据分析了“大气十条”实施的五年期间主要大气污染物的时序变化特征,进而运用因子分析法计算了各污染物之间相关性。通过日均浓度值计算AQI,得到了哈尔滨市2013年-2017年的空气达标状况和首要污染物的情况。结果表明:各污染物浓度存在明显的季节变化规律,在“大气十条”实施五年内主要污染物浓度呈显著下降趋势,达标率呈逐年上升趋势,首要污染物仍为细颗粒物。分析结果可为下一阶段哈尔滨空气污染治理提供基础信息和建议。

Based on the pollutant concentration in the control points of Harbin from 2013 to 2017,combined with the meteorological data,the time series characteristics of the main air pollutants during the five-year period of the implementation of the“Ten Atmospheric Regulations”were analyzed.The correlation among the pollutants was calculated by the factor analysis method.By calculating AQI of daily average concentration values,the air standard and primary pollutants of Harbin in 2013-2017 were obtained.The results showed that there was an obvious seasonal variation of the concentrations of the pollutants.In the five years since the implementation of the“Ten Atmospheric Regulations”,the concentrations of the main pollutants had a significant downward trend,and the rate of reaching the standard had an upward trend year by year.The main pollutants were still fine particles.The analysis results can provide basic information and suggestions for the next stage of air pollution control in Harbin.
