摘　　要：[目的]对奎屯市降尘分布特征进行初步研究,以期为环保部门提供依据。[方法]将奎屯市分为工业、商业、居民、生态4个功能区,并进行为时一年的大气降尘实时监测,在此基础上分析该市降尘污染的时空分布特征。[结果]各功能区降尘量最高的月份出现在4～7月份,年降尘累积总量表现为工业区>商业区>居民区>生态区,每月35.44～118.21t/km2,方差分析显示,工业区、商业区、居民区与生态区之间差异有统计学意义。[结论]奎屯市城市大气降尘污染虽有下降趋势,但仍需加强大气污染控制的综合防治措施。[Objective] To study urba（Kuitun City）dust fall pollution characteristics and its time-spatial distribution for the use of environmental protection section.[Methods] Based on the actual situation in Kuitun,the amount and time-spatial distribution of dust fall in four functional areas were monitored.[Results] The amount of dust fall in each functional area reached highest in April through July.Total amount of dust accumulated was 35.44~118.21 t/（km2·month）in the order that industrial area business area residential area ecological zone.By analysis of variance,the amount of dust fall had very significant differences between the four zones.[Conclusion] The amount of atmospheric dust fall pollution has a decline tendency in Kuitun City,but it still results in healthy hazards of residents.So it is very necessary to strengthen comprehensive prevention measures in atmospheric pollution control.
