摘　　要：利用 2 0 0 1年 6、7月份在新疆天山山区两个取样点取得的冰核资料 ,计算了山区中的冰核浓度 ,研究了冰核平均浓度日变化、日际变化的规律 ,并分析了天山山区冰核浓度与一些气象因子的关系及可能原因。得出以下结论 :天山山区的大气冰核主要来源于地面土壤 ,比较缺乏 ;冰核浓度易受气象因子、地表状况的影响 ,日变化和日际变化明显。The concentration of atmospheric ice nuclei was observed in Tianshan Mountain area from June to July in 2001.Daily variation and Interdiurnal variation of the average concentration of atmospheric ice nuclei were investigated.Relationship between the concentration of atmospheric ice nuclei and affecting meteorological factors was investigated and some possible reasons were addressed.The results show that atmospheric ice nuclei in Tianshan Mountain area comes from soil and is depleted in the air.The concentration of atmospheric ice nuclei depends on meteorological and ground conditions,and changes significantly not only within a day but also from day to day.
