The modern seafloor hydrothermal activities play great roles in the earth system. It is characteristic of the high-effective interaction among the geological processes concerning the sea, the oceanic crust, and the upper mantle. The hydrothermal circulation is constrained by magmatic activities and tectonic movements. On the other hand, the expel of the hydrothermal fluids results in many geological effects, such as the seafloor mineralization, the heat anomaly of regional seawater, the life depending on the hydrothermal vents, which occur as an integral system and it is necessary to study the hydrothermal activities and the effected environments systematically. In order to study the internal dynamic characteristics and its external effects, especially their relations, four parts are analyzed about the hydrothermal system: the spatial structure of the hydrothermal circulation, the heat transmitting process, the chemical composition of the hydrothermal fluids, the implication between hydrothermal activities and the extreme life. In the end, the significance and prospect of the hydrothermal system study are introduced.
