| 摘 要： | 对云南省几个不同地区的强震孕震阶段及临震时的地震空间分维Ｄｑ（ｑ＝０，１，２，）及ｂ值进行了计算和研究，发现虽然在孕震阶段各地区的Ｄｑ及ｂ值均有着共同的下降主趋势，但临震时不同区域的Ｄｑ及ｂ的变化形态却存在着差异，大地震可能发生在Ｄｑ及ｂ值均降至最低时，也可能发生在Ｄｑ及ｂ值下降后又回升之时，还可能发生在Ｄｑ回升而ｂ值仍保持最低时。本着重对Ｄｑ及ｂ值的临震变化特征及其个体差异从非线性的角度作了物

| Abstract: | Seismic spatial fractal dimension Dq and b Value in different areas of Yunnan Province during seismogenic period and earthquake-impending time are calculated and studied. The results indicate that the variation patterns of Dq and b value in different areas have commom descendant tendency during seismogenic period,but with different earthquake-impending time.Strong earthquakes probably happen at the lowest valu of Dq and b value,or at the time of Dq and b value's rising again after a fall,or at the time of value's fall but Dq's rising again.This paper has emphatically explored the mechanism of earthquake-impending characteristics and their individual differences from the non-linear view.The characteristics and differences are closely ralated to the seismogenic system of interior non-linear nature and interaction. |
