主　　题：Fractal and fractal dimension fault tectonic region China 

摘      要：The distribution of deep fractures in the China continental crustobody shows fractal structure features. The fractal dimension value of fractures is 1. 493 for the whole continent and 0. 827~ 1. 624 for different tectonic regions. The fractal dimension value of fractures in mobile regions (especially diwa regions) which is 1. 236 ~ 1. 624 is obviously larger than that in stable regions: platform regions which is 0. 827~ 1. 074, and the fractal dimension value of fractures in the jointregions of crustobodies is obviously larger than that in inner regions of a crustobody. The fractal dimension value of fractures reflects the complexity of regional tectonic evolution, movement history and the intensity of tectonic activity. Therefore, fractal dimension of fractures is a quantitative parameter representing geotectonic characteristics.
