2018年黑龙江省环境空气质量时空变化特征分析研究

Analysis of Spatial and Temporal Variation Characteristics of Environmental Air Quality in Heilong Province in 2018

黑龙江省是中国最北端的省级行政区,属于国界省份,环境空气质量状况备受关注。文章通过2018年黑龙江省47个地面空气质量监测站的数据,使用空间插值、统计分析等方法,来研究2018年黑龙江省环境空气质量的时空变化规律。根据黑龙江省的地域特点,对采暖期和非采暖期空气质量进行对比分析,并探究主要污染指标PM2.5和PM10浓度的空间分布规律。研究结果表明,2018年黑龙江省环境空气质量明显改善,采暖期空气质量状况要比非采暖期差,重点区域污染仍比较突出。

Since 2012,the problem of haze has been concerned by the people of our country.Heilongjiang Province is the northernmost provincial administrative region of our country,belonging to the border province.The quality of ambient air has attracted much attention.Based on the data of 47 ground air quality monitoring stations in Heilongjiang Province from 2016 to 2018,this paper studies the temporal and spatial variation of air quality by means of spatial interpolation and statistical analysis.According to the regional characteristics of Heilongjiang Province,the air quality of the heating period and the non-heating period is compared and analyzed.This paper explores the spatial distribution of PM 2.5 and PM 10 concentrations in the main pollution indexes.The results show that,the environmental air quality in Heilongjiang Province is gradually improved,and the air quality in heating period is worse than that in non-heating period,and the pollution in key areas is still more prominent.
