本文提供了丽江７０级地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象；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的短临阶段具有重要的指示意义 This paper presents the anomalous images of the spatial dimension, correlation dimension and information entropy of seismic activity in the northwestern Yunnan before the 7.0  7.0 earthquake; these anomalies occurred after the formation of the seismogenic zone and acceleration of strain release stage, exactly Reveals the non-linear changes before source and source regions are released. This is consistent with the conclusion that the fractal studies of 8 groups of major earthquakes in Yunnan and its adjacent areas since 1965 have made the conclusion that the fractal anomaly of seismicity is an important indicator for the short and early stages of earthquake gestation
