【摘要】 １９９０年青海共和７．０级地震是构造地震还是水库畜水诱发地震？黄河上游龙羊峡水库周围地区的无线遥测地震台网在８年运行中记录了丰富的地震资料，共和地震后就记录到余震８，１４５个，为上述问题的研究积累了丰富的资料和数据。近来，特别是１９９４年，５．０级以上地震在这一地区呈增多趋势。因此，龙羊峡水库周围是值得地震研究人员密切注视和研究的地区。更多还原

【Abstract】 An earthquake(Ms 7.0)occurred in Gonghe county,Qinghai Province,on Apr.26,1990.Is it a tectonic earthquake or a reservior earthquake ? The telemetric seismic networkaround the Longyangxia reservior has recorded a wealth of earthquake data for the past 8years,only after the Gonghe earthquake,the network recorded 8,145 aftershocks,thus pro-vides rich data for solution of the above-mentioned problem,There have been more and moreMs≥5.0 earthquakes in the region since 1994.Therefore,the Longyangxia reservior regionInerits seismologists attention and studies.更多还原
