摘　　要：经过近半个世纪的发展,2022年云南定点形变台网向国家中心报送数据的观测站点已有17个,这些站点主要分布在云南6.0级以上地震频发区。本研究通过对2022年本省定点形变观测数据形态变化、观测精度计算、观测日志及工作日志梳理,对云南定点形变数据的观测背景。及其变化态势进行综述。After nearly half a century of development,17 observation stations in Yunnan’s fixed-point deformation network have submitted data to the National Geophysical Data Center in 2022.These stations are mainly located in areas with frequent earthquakes of magnitude 6.0 and above in Yunnan.This study provides an overview of the observation background and trend of fixed-point deformation data in Yunnan Province in 2022 by analyzing the morphological changes,observation accuracy calculations,observation logs,and work logs.
