摘　　要：基于临汾市2019—2023年大气降尘监测数据,分析了大气降尘的时空分布规律,绘制了临汾市降尘空间分布图,利用相关系数法识别影响临汾市大气降尘的主要因素。结果表明:临汾市近5 a降尘量较稳定,降尘污染程度较轻;降尘量季节变化规律为春季>夏季>冬季>秋季;月降尘量一般3—5月达到最高,9—10月达到低值。各区县降尘量差异较小,整体呈现出自中西部向四周逐渐降低的趋势。自然因素是临汾市大气降尘量变化的主要因素,人类活动是影响降尘量增加的重要因素。Based on the data of dustfall in Linfen from 2019 to 2023,the temporal and spatial distribution law of dustfall and correlation coefficient method to identify the main factors of dustfall were analyzed in this research.The spatial distribution map of dustfall in Linfen was drawn by using ArcGIS.The results show that the dustfall in Linfen is stable and the degree of dust pollution is relatively light in the past 5 years.The seasonal variation of dust fall in the city is spring>summer>winter>autumn.The monthly dust fall generally reaches the highest level in March,April or May,and the lowest level in September or October.The difference of dustfall among different districts is small,and the overall trend is gradually decreasing from the central and western regions to the surrounding regions.Natural factors was the primary factors influencing the variation of dustfall in Linfen,while human activities are the significant factors.
