| 摘 要： | 以形变(倾斜、应变)观测资料，采用经过实效检验分析后有效率较高的形变前兆参量及异常判别方法，以近年来发生在滇西地区的6级以上地震：武定地震、丽江地震、宁蒗地震以及姚安地震的震例，用滇西及川滇交界地区形变观测网的资料进行综合分析，重点对该地区强震前兆异常的时空演化及特征进行分析研究，对其在强震前中短阶段的前兆异常变化的基本特征进行了探讨。

| Abstract: | In recent years, several strong earthquakes such as Wuding earthquake, Lijiang Earthquake, Ninglang Earthquake and Yao'an Earthquake occurred successively in west Yunnan Province.Taking these earthquakes as the samples, a synthetic analysis of the data got through deformation-observation network in west Yunnan and in the Sichuan-Yunnan boundary region is made.The analysis is based on the precursory parameters of deformation and the anomaly-discriminating method and they have been proved to be very effective in the earthquake prediction.Further, the analysis focuses on the evolvement of precursory anomalies in time and space and the related basic characteristics in the mid-short term stage before strong earthquake occurs. |
