该文提供了1996年2月丽江7.0级大震前滇西北地震活动空间容量维、关联维、信息熵十分显著的异常图像；这些异常是在大震孕震区形成、应变释放加速阶段之后出现的，恰好揭示了源区、近源区大释放前的非线性变化过程。这与1965年以来云南及邻区8组大震前地震分形研究的结论完全一致；进一步说明地震活动分形异常对地震孕育阶段具有重要的指示意义。
This paper presents the anomaly images of spatial capacity dimension, correlation dimension and information entropy of seismic activity in Northwestern Yunnan before the MS 7.0 Ms 7.0 earthquake. These anomalies occurred in the seismogenic zone of large earthquakes and accelerated after the release of strain , Just revealed the non-linear change of the source area and the near source area before release. This is in good agreement with the conclusion that the fractal studies of the eight groups of major earthquakes in Yunnan and its neighboring areas since 1965 have shown that fractal anomalies in seismicity are important indicators for the gestation period.
