摘　　要：本文对地震定位产生误差的原因进行分析，并且对提高地震定位精度的方法进行了研究．随着沈阳数字化地震台网即将投入运行，需要将原有的在ＤＯＳ环境下运行，用ＢＡＳＩＣ语言编写的地震定位软件，移植到新的系统运行环境．并且在吸收原定位系统的优点的基础上作了重大改进，进一步提高了网缘地震定位精度和可靠性．对提高地震台网监测能力有重大的意义．The cause of error due to locating earthquake is analyzed in this paper, and the method of improvingprecision of locating earthquke is also studied. Original locating earthquake soffware,which is applicable for DOSsystem by means of Basic langUage, will be tranSPlanted to new system along with application of Shenyang DigitalSeismological Network. So improving original software is necessary.
