| 摘 要： | 对1976—2001年云南38组M≥5地震震例中地下水宏观异常进行统计分析，得到这些震例地下水宏观异常的共同特征；再对2011—2021年云南各地州、市通过地震行业内网上报的755项宏观异常中705项地下水宏观异常进行梳理；参照震例中地下水宏观异常的共同特征对云南M≥5地震与地下水宏观异常间的关系进行分析。结果表明，云南地区地下水宏观异常出现在震前3个月内的、出现在极震区内的比例均为100%。

| Abstract: | Based on the statistics and analysis of the macro-anomaly characteristics of groundwater in 38 groups of M≥5 earthquakes from 1976 to 2001 in Yunnan Province, the common characteristics of macro-anomaly of groundwater in earthquake cases in Yunnan Province are obtained. Then, 705 of the total 755 macro-anomalies of groundwater reported by various provinces and cities in Yunnan Province from 2011 to 2021 were sorted out. According to the common characteristics of macro-anomaly of groundwater in earthquake cases, the correlation between earthquakes with magnitude larger than 5 and the macro anomalies of groundwater is analyzed, and the results show that the macro-anomaly of groundwater in Yunnan area accounts for 100% in 3 months before the earthquake and 100% in the extreme earthquake area. |
