摘　　要：Using multifractal spectrum estimating method based on the wavelet, the multifractal characteristics of GSR of earthquakes in China, Japan and New Zealand regions have been studied. It is shown that the multifractal spectra of GSR are obviously different in inter- and intra- plate regions. Moreover, though Japan and New Zealand are all located at the boundary of plates, West and East China are all characterized of continental tectonic structure, the multifractal spectra of GSR for both the two regions are also different. Further analysis shows that the natures of multifractal spectra of GSR are somehow related to the complexity of tectonics.Using multifractal spectrum estimating method based on the wavelet, the multifractal characteristics of GSR of earthquakes in China, Japan and New Zealand regions have been studied.
