西双版纳州大气污染与气象因子分析

Analysis of air pollution and meteorological factors in Xishuangbanna

基于对2015~2020年3月西双版纳州景洪市逐日、逐时地面气象的观察,和对空气质量观测数据资料的梳理,本文采用统计的方法,对大气污染物及AQI指数的年际变化、月际变化、日变化及小时变化展开研究,并分析大气污染物及AQI指数与各气象因子、火源点多少的相关性,最终得出结论:大气污染物与日照、气压呈显著正相关,与水汽压、温度、湿度、降雨量、风速呈显著负相关。大气污染物浓度除了受气象因子影响外,还受到火源点数量多少的影响。

Based on the daily and hourly ground meteorological observation of Jinghong City in Xishuangbanna from March 2015 to March 2020,and combing the air quality observation data,this paper adopts statistical method to study the interannual,monthly,daily and hourly changes of air pollutants and AQI index,and analyzes the air pollutants,AQI index,meteorological factors and fire sources Finally,it is concluded that air pollutants are significantly positively correlated with sunshine and air pressure,and negatively correlated with vapor pressure,temperature,humidity,rainfall,humidity and wind speed.In addition to meteorological factors,the concentration of air pollutants is also affected by the number of fire sources.
