摘　　要：简要介绍黑龙江省测震台网监测能力,并通过地震编目资料分析1900年以来黑龙江省地震分布特征。结果显示:黑龙江省编目地震以4级以下地震为主,6级以上地震较少;非天然地震主要为矿震和爆破事件;6级以上地震均为天然地震,主要分布在扶余—肇东断裂、呼兰河断裂、密山—敦化断裂、吉林与黑龙江交界深震区。The monitoring capability of seismic network in Heilongjiang Province is briefly introduced,and the distribution characteristics of earthquakes in Heilongjiang Province since 1900 are analyzed by seismic cataloguing data.The results show that most of the cataloged earthquakes in Heilongjiang Province are smaller than M 4,and few are bigger than M 6.The non-natural earthquakes mainly are mine earthquakes and blasting events.M≥6 earthquakesare all natural earthquakes,mainly distributed in Fuyu-Zhaodong fault,Hulan River fault,Mishan-Dunhua fault,Jilin and Heilongjiang border deep earthquake area.
