The invention relates to a microalgae system for adsorbing CO2 and a preparation method thereof, and the preparation method comprises the following steps: preparing a metal organic framework, and culturing the prepared metal organic framework and microalgae together to form the microalgae system, wherein functional groups such as carboxyl, amino and phosphate on the surfaces of microalgae cells can interact with an active site-amino on the surface of the metal organic framework, and the interaction can stabilize the protein structure and function of the microalgae and prevent the microalgae from being inactivated or degraded in the culture process; the microalgae can also perform diffusion propagation by utilizing organic groups on the metal organic framework, and the surface and internal pore structures in the metal organic framework can guide the distribution and arrangement mode of the diffusion propagation of the microalgae, so that the microalgae propagates and diffuses to gradually form a layer of thin
