2. Abstract In this paper, we give a brief introduction to our investigation and tentative idea for Virtual Geomagnetic Observatory ­­ in china, including its basic constitute. There is also the expression of the desire to find the way for cooperation with international resolve of Virtual Geomagnetic Observatory.
