摘要
以森林覆盖率及其他空气污染物(PM10、CO、NO2、SO2、O38 h)和气象因素(气压、相对湿度、光照数、气温、风速)为研究指标,以黑龙江省13个市(区)为对象,应用3 a数据、依据面板数据模型分析PM2.5与森林覆盖率及其他空气污染物和气象因素之间的关系。结果表明:森林覆盖率较高城市的PM2.5质量浓度,低于森林覆盖率较低城市的PM2.5质量浓度。森林覆盖率是阻滞PM2.5质量浓度增高最主要的因素,其他空气污染物是导致PM2.5质量浓度升高的根本原因,气象因素对PM2.5质量浓度变化所起的作用较小。
Taking forest coverage and other air pollutants(PM10,CO,NO2,SO2,O38 h)and meteorological factors(barometric pressure,relative humidity,average daylight duration,temperature,wind speed)as research indicators,13 cities(districts)in Heilongjiang Province were used as objects,the relationship between PM2.5 and forest coverage rate,other air pollutants and meteorological factors were analyzed with 3-a data and panel data models.The PM2.5 concentration in cities with higher forest cover was lower than that in cities with lower forest cover.Forest coverage rate is the most important factor that retards the increase in PM2.5 concentration.Other air pollutants were the root cause of PM2.5 concentration increase.Meteorological factors have a smaller effect on PM2.5 concentration changes.
