Abstract: By using energy flux density method,seismic energy release in Kunming and the surrounding region(23.6°N～27.0°N,101.5°E～104.5°E)was calculated,and the contour maps of energy flux density logarithm values were obtained.Then the situation of the seismic energy release in each period was obtained by analyzing the contour map.The spatial temporal distribution characters of seismic activity in Kunming and the surrounding region was obtained by studying the region of the energy release,and its strength cycle and the variable trend.The results showed that the seismic activity of that region becomes stronger.The reference value of energy flux density map in the division of potential source zone and earthquake prediction was discussed at last.
