In this paper, the data of the digital network in Zhangye district have been treated, and the Parameters of the events have been obtained. The spectral analysing for a part of events in Sunan has been made, the spectral parameters have been estimated. The source mechanisms and dislocating Parameters of the micro-events in Sunan have been converted using the method of amplitude ratio, the significance for tectonics and predietion have been discussed preliminarily. Finally, the advance work is suggested.
