Abstract
Based on the dustfall data of 14 monitoring points in Urumqi from 2017 to 2023,variance statistical methods was used to analyse temporal and spatial distribution characteristics of dustfall in Urumqi.Spearman rank correlation coefficient method was applied to predict the trend of dustfall in Urumqi.The results showed that dustfall of 2018 was higher than that in other years.The seasonal variation characteristics of dustfall presented the feature of spring>summer>winter>autumn.The dustfall from April to June were generally higher than that in other months.The average value of dustfall in non-heating period was generally higher than heating period.The high value areas of dustfall were concentrated in the central and northern parts of main urban area in Urumqi,while the low value areas of dustfall were concentrated in the southern parts of main urban area in Urumqi.According to the prediction,the amount of dustfall in Urumqi was showed a downward trend,but the trend was not significant.The dust weather had a certain impact on dustfall.It was suggested to strengthen the prediction and forecast of dust weather.关键词
