| 摘 要： | 以１９８９￣１９９７年北祁连河西地区流动重力监测资料为基础，分为１９８９￣１９９１、１９９１￣１９９５、１９９５￣１９９７年三个时段，定性定量分析了这三个时段该地区重力的时空变化特征，得出了北祁连河西地区的重力场现处于祁连山重力值上升、河西走廊重力下降的逆继承性重力变化的结论。

| Abstract: | Based of the mobil gravity data in the North Qilian-Hexi region in the three intervals, 1989-1991, 1991-1995 and 1995-1997 from 1989 to 1997, the time-space variation characteristics of gravity in the three intervals are analyzed both qualitatively and quantitatively. The results show that the gravity values in the Qilian Mountain are rising and ones in the Hexi Corridor are falling now, which is called an inverse inheritance variation in gravity. |
