The invention discloses an ocean space valley serving as a science investigation station, and relates to a building for ocean science investigation and research base. The invention provides an energy-saving and environmentally-friendly ocean space valley serving as marine long-lasting engineering and scientific research base and having good moving performance and stability. In the technical scheme in the invention, an upper building, a middle building and a lower building are adopted and the invention is characterized in that: the upper building body is a conical body, the middle building body is a columnar body, and the lower building body is a conical body; the upper conical body, the middle columnar body and the lower conical body form the building which basically appears like a hyperbolic curve and is internally provided with a curved columnar central channel; the lower conical body is provided with a moon pool area; and an openable door is arranged at the bottom of the moon pool area so as to put instrument and equipment down to the seawater. The ocean space valley disclosed by the invention is suitable for being used as a base for long-lasting observation, test and research of ocean science.
