摘    要:通过对"十一五"期间新疆134个大气降尘监测点位数据进行统计分析发现,"十一五"期间,全疆年均降尘量维持在22.2~24.6 t/km2.月,变化幅度小于10%。一年内降尘主要集中在3~6月份,占全年降尘量的51%。在空间分布上,新疆年均降尘量呈现明显的南疆高于北疆的特征,南疆五地、州的总降尘量占全疆总降尘量的70.2%,为新疆降尘的主要集中区。特殊的气象、生态环境是决定新疆大气降尘时空分布特征的主要因素。

Abstract:The 134 atmospheric dust monitoring point data in Xinjiang in the "Eleventh Five- Year" period were analyzed, statistic found that the "Eleventh Five- Year" period, Xinjiang annual dust fall was maintained at 22.2 - 24.6 t/kinzm, change by less than 1096. Within one year of dust fall is mainly concentrated in the March to June, accounting for 51% of the annual dust fall. On the spatial distribution, the average annual dust fall in Xinjiang showing the characteristics of the southern is higher than the northern, southern Xinjiang, the state's total dust fall accounted for Xinjiang dust fall 70.2% for the dust fall concentration area in Xinjiang. Special meteorological, ecological environment are to determine the dust fall temporal and spatial distribution in Xinjiang.
Keywords:Eleventh Five- Year  Xinjiang  aanospheric dust fall  temporal and spatial distribution  influencing factors
