| Abstract: | In this paper we outlined the chaotic attractor of the precursory field evolution of the seismogenic system and its fractal
dimension of the precursory time and space distribution. We developed the calculative method of reconstruction complex system
dynamics from single time series and analysed the descent dimension phenomena of the precursory distribution before large
earthquakes. We also showed the time-space synthesis method constructed complex system dynamics by many stations or many methodes
in the seismogenic system consists of large area tectonic network. This method can describe the self-organization behavior
of the system more accurately and get rid of the uncertainty and randomness caused by single station or single method. As
an example, we calculated the chaotic attractor of the precursory field evolution and the fractal dimension of the precursory
time and space distribution and its change tendencies before large earthquakes in Beijing-Tianjing area.
