摘　　要：文章讨论了秋季（１９９年１０月）和冬季（１９９年１月）在中国西部青海省共和县瓦里关山（３６°１７′Ｎ，１００°５４′Ｅ，海拔３８１６ｍ）基准站和中国东北黑龙江省五常县的龙凤山（４４°４４′Ｎ，１２７°３６′Ｅ，海拔３３１ｍ）及中国东南沿海的浙江省临安县的横贩乡（３０°１８′Ｎ，１１９°４４′Ｅ，海拔１３１ｍ）两个区域本底站（上述３站均属ＷＭＯ）所采集的气溶胶样品的质量浓度、可溶性离子浓度的时空分布特征和变化规律．初步得出：气溶胶质量浓度和可溶性离子浓度以临安为最高，其次是龙凤山，而瓦里关山为最低；气溶胶的质量浓度各站均以秋季高于冬季．此外，还讨论了风及某些微量气体对气溶胶浓度分布特征的影响．The spatial and temperal distribution characteristics and variation regularity of massconcentration of aerosol and water soluble ionic concentration for the samples collected atWaliguanshan Mt. baseline station(36°17′N, 100°54′E, 3816 m SLE), Longfengshan Mt.(44°44′N, 127°36′127° 33′ m SLE)and Lin′an (30°18′N, 119°44′E, 131 m SLE) regionalbackground stations in autumn (October 1994)and winter (January 1995) were analyzed.The priliminary conclusion was drawn as follows: the highest values of mass concentrationof aerosol and water soluble ionic concentration were observed at Lin'an, the middle atLongfengshan Mt. and the lowest at Waliguanshan Mt. ; the mass concentrations of aerosolwere higher in autumn than in winter at all the three stations. In addition, the impacts ofwinds and some trace gases on the concentration distribution characteristics of aerosol werealso discussed.
