| 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。

| Abstract: | Based on analysis of the ground fluid precursor observation date ot cl：gltai ano analogous m 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. |
