摘要
利用沙尘天气观测资料和颗粒物浓度监测数据,分析了沙尘天气对巴楚县大气环境的影响。结果表明:(1)影响巴楚县空气质量的沙尘天气有沙尘暴、扬沙和浮尘,年均沙尘日数高达156 d,其中浮尘日数最多。(2)巴楚县沙尘天气主要集中在春季。(3)塔克拉玛干沙漠以及塔里木盆地边缘裸露的沙地是巴楚县的沙尘天气的沙源地,春、夏季强劲冷空气进入南疆盆地时产生的大风是沙尘天气的动力条件。特殊的地理环境是造成巴楚县沙尘天气频发的主要原因。(4)沙尘天气对巴楚县AQI指数、PM_(10)、PM2.5浓度有明显影响,NO2、CO、O_(3)和SO_(2)等污染物受沙尘天气影响不明显。
This article analyzed the impact of sandstorms on the air quality in Bachu County.The results showed that:(1)Sandstorms that affects the air quality in Bachu County included sandstorms,blowing sand,and floating dust,with an average of 156 dust days per year,of which floating dust days were the most.(2)The occurrence of sandstorm weather in Bachu County showed a significant decreasing trend over time,and it was mainly concentrated in the spring.(3)The Taklimakan Desert was the sand sources of sandstorm weather in Bachu County.The strong cold air entering the southern Xinjiang Basin in spring and summer was the dynamic condition for sandstorm weather.The special geographical environment was the main reason for the frequent occurrence of sandstorm weather in Bachu County.(4)sandstorm weather has a significant impact on the AQI index,PM_(10),and PM_(2.5) concentrations in Bachu County,but the pollutants such as NO_(2),CO,O_(3),and SO_(2) were not significantly affected by sand and dust weather.
