泸州市城区PM2.5与地面烟炉增雨消霾关系浅析

Analysis of the Relationship Between PM2.5 and Precipitation Enhancement and Haze Reduction by Ground Flue Gas Furnace in Urban Areas of Luzhou

    摘要
  • 摘要: 利用泸州市2018~2020年的空气污染监测数据，气象数据，地面烟炉增雨消霾作业数据，用统计归纳方法研究了泸州市城区PM2.5与地面烟炉增雨消霾的关系。结果表明：进行增雨消霾作业是十分有效的，作业后PM2.5等级均有降低，递减等级情况为：递减1级有10个，2级有22个，3级有11 个，PM2.5递减率从8.51~56.02%；建立PM2.5与地面烟炉增雨作业模型F(P) = 0.3998*R + 0.0761*A − 0.0202*S −0.0012*m + 2.38，R2 = 0.6323，通过了a = 0.05的F检验；通过3个地面烟炉增雨作业站点进行人工增雨作业，可以成功降低PM2.5。

     

    Abstract: Based on the air pollution monitoring data, meteorological data and the operation data of precipitation enhancement and haze reduction by ground flue gas furnace in Luzhou from 2018 to 2020, this paper studies the relationship between PM2.5 and precipitation enhancement and haze reduction by ground flue gas furnace with statistical induction method. The results show that: Precipitation enhancement and haze reduction are effective, and PM2.5 grades are all reduced after the operation. The diminishing grades are: 10 for grade 1, 22 for grade 2 and 11 for grade 3, and the diminishing rate of PM2.5 is from 8.51 % to 56.02 %. The model of PM2.5 and precipitation enhancement by ground flue gas furnace is established as F(P)=0.3998*R+0.0761*A−0.0202*S−0.0012*m+2.38, R2=0.6323, which passes the F test of a = 0.05. PM2.5 can be successfully reduced by artificial precipitation at three stations for precipitation enhancement by ground flue gas furnace.
