摘　　要：本文概述了黑龙江省五大连池火山群中两座近代火山老黑山、火烧山的基本情况,浮岩碎屑堆积物和熔岩流的分布和特点。在此基础上,论证了老黑山火山不是单成因火山,火烧山可归属为单成因火山;火山喷发活动过程的特点是先裂隙式喷发、后转为中心式喷发;浮岩碎屑喷发是同岩浆喷溢伴随发生的。并同冰岛拉基火山(Laki volcanoes)、美国夏威夷火山及意大利斯通博利火山进行了对比,提出了应把中国黑龙江五大连池老黑山火山喷发类型命名为"五大连池老黑山型",即一种兼有上述火山的特点,又同它们有明显差别的新的火山喷发类型。这种观点对于评估五大连池火山再次喷发的危险性和预测预报火山灾害,以及丰富对火山喷发类型的认识均有理论和实际意义。This paper demonstrates the basic situation of two mordern volcanoes,Laoheishan and Huoshaoshan, in the Wudalianchi volcanic group,and the distribution and characterestics of pumicecinder fragments and lava flows. On this basis, the authors propose that:①the Laoheishan volcano is not a monogentic volcano; ② volcanic eruption is characterized by fissure eruption at first and then central-vent eruption;③ eruption of pumice-cinder fragments and magma eruption happened at the same time;④compared with the Icelandic Laki Volcano,Italy Strombolian Volcano and American Hawaiian Volcanoes; it is pointed out that the eruption type of the Laoheishan volcano in Wudalianchi has a new type of volcanic eruption, which was named 'the Wudalianchi Laoheishan Type '.
