摘　　要：吉林省地震监测台网自数字化观测以来,地震监测能力和速报速度明显提高,但东部的延边地区测震台网密度仍相对偏低。为了进一步提升该区地震监测能力,中国地震局拟在吉林省延边州龙井市建设1个地震台阵,采用圆形阵列方式布设,孔径设为3 km,由9个子台组成。通过图上勘选、宏观勘选、仪器勘选,最终确定9个台点的具体位置,并给出布台方案,为今后实地建设台站打下坚实基础。The seismic monitoring capability and the earthquake quick-report have increased significantly since the digitization of the Jilin seismic monitoring network.However,the network density in the eastern Yanbian area is relatively low.In order to further improve the seismic monitoring capability of the eastern region,China Earthquake Administration plans to build a seismic array in Longjing City,Yanbian Prefecture,Jilin Province.The seismic array consists of 9 sub-stations that are distributed in a circular shape with a diameter of about 3 km.After the selection on the map,site survey,and instrument observation survey,the specific locations of 9 stations are finally determined and the layout scheme of each site is given.These make a solid foundation for the future field construction of the array stations.
