摘要
通过林芝市2017年4-6月环境空气质量资料及紫外线辐射强度观测值,对紫外线辐射强度与空气质量的相关性关系进行研究。结果表明:紫外线辐射强度中午前后最强,最大值可达70 W/m^2,早晚最弱,最小值为0.01 W/m^2;紫外线辐射等级为5级的时间占总观测时长的55.87%,超过一半以上;紫外线辐射强度与NO_2呈较明显的负相关,Pearson相关系数为-0.242;与O_3呈较明显的正相关,Pearson相关系数为0.233,两者均通过显著性检验;与AQI、PM_(2.5)、PM_(10)、SO_2、CO均无较好的相关性,未通过显著性检验。
The relationship between the intensity of ultraviolet radiation and the air quality was studied through the environmental air quality data and ultraviolet radiation intensity observation values from April to June,2017 in Linzhi,Tibet.The results show that the intensity of ultraviolet radiation is the strongest at noon,with the maximum value as 70 W/m2,while it becomes weaker in the morning and evening,with the weakest and the minimum as 0.01 W/m2.The time of ultraviolet radiation was 55.87%of the total observation time.The correlation coefficient between UV radiation intensity and NO2was-0.242;and the UV radiation intensity was positively correlated with O3,with Pearson correlation coefficient as 0.233,both of which were examined by significance test.There was no significant correlation between ultraviolet radiation intensity and AQI,PM2.5and PM10,SO2,CO,which did not pass the significance test.
