摘　　要：采用拟稳平差对关中地区近二十年的流动重力观测资料进行处理,并结合其他观测资料和研究结果,对区域重力场变化过程、三次中小地震前后重力场变化机理、构造活动以及区内外地震关系进行了分析。Observation data of mobile gravity in Guanzhong region in recent 20 years are reprocessed by using quasi-stable adjustment method, and combing with other observation data and research results, the variation process of regional gravity field, gravity field variation characteristics before and after three medium and small earthquakes,tectonic activity and earthquake relations are analyzed profoundly.
