摘要

分析云南地区数字化和模拟前兆观测资料,确认滇东北及邻区水富水位、渔洞水位、曲靖地温及丽江地温等流体典型异常,与汶川8.0级地震的孕育及发生有关。分析认为:①汶川地震的典型流体异常与云南强震异常具有相似性;②汶川地震孕育与发生影响的区域性与多样性;③水温中期异常和数字化分钟值异常是值得关注的新异常现象。
Based on analysis of the ground fluid precursor observation date of digital and analogous in Yunnan region, we confirm that the typical precursor anomaly of ground fluid in northeast Yunnan region, such as water-level of Shuifu and Yudong well, the water temperature of Qujing and Lijiang well etc. relates to the gestation of Wenchuan earthquake. By analysis, we know that; ①the typical precursor anomaly of ground fluid of Wenchuan earthquake is similar to the precursor anomaly of strong earthquake in Yunnan; ②the influence of gestation and occurrence of Wenchuan earthquake is territorial and varietal; ③the water temperature of medium-term and minute value anomalies is new anomaly phenomena.
