摘　　要：根据汶川8.0级地震后各地上报的宏观异常现象,开展调查分析。这些宏观异常现象主要包括动物异常、地下水位异常、地象异常。地震序列前期宏观异常现象出现多,后期出现少。2008年5月25日青川6.4级地震前后几天出现的宏观异常现象相对更突出。研究认为,汶川8.0级地震后大量宏观异常现象分布范围很广。其中,地象异常以及地下水位宏观异常现象集中,主要沿龙门山前山断裂带分布。The macroscopic seismic phenomena after Wenchuan Ms 8.0 in Sichuan provincc are analyzed, and these phenomena include the anomalies of animals, underground water levels and surface configuration. The phenomena appeared more at the beginning of the earthquake sequence than at the end, especially on May 25, 2008. And the phenomena appeared in large area, and the surface anomalies and underground water Icyels anomalies mainly scattered along Longmenshan fault.
