摘　　要：利用新疆区域多年的流动重力和连续重力资料对新疆的重力场时空特征进行研究,结果表明:2016~2017年南天山地区显示乌恰至喀什一带出现重力高梯度带的密集区域,北天山地区显示新源至巩乃斯一带重力测量出现较为明显的四象限分布。乌什台和库尔勒台的非潮汐变化在M S 6.0地震之前有一定的反应。Study the temporal and spatial characteristics of gravity field with the data of mobile gravity and continuous gravity for many years in Xinjiang.The results show that:The high gradient zone of mobile gravity appeared in Wuqia to Kashi region in Southern Tianshan on 2016~2017.The four quadrant distribution from Xinyuan to Gongnaisi is obvious in Northern Tianshan.According to the analysis of continuous gravity,the non-tidal changes of Wushi and Korla had a certain reaction before MS6.0 earthquake.
