摘　　要：对兰州—天水—武都地区重力网 1 991～ 1 999年 9期复测的重力资料进行了对比分析 .结合地质构造分析了重力场变化与永登 5 .8级和宕昌 3.9级地震的关系 .结果表明 ,这 2次地震前后 。The 9 years gravity informations measured from 1991 to 1999 in Lanzhou-Wudu-Tianshui area are analyzed and compared.The relationship of gravity with the Yongdeng M S5.8 earthquake on July 22,1995 and Tanchang M S3.9 earthquake on Nov. 18,1998 is discussed by considering geologic structures.The results show that there were obvious gravity changes near the epicenters before and after the two earthquakes.
