The invention provides a method for repairing a slope ecological protection base material by multi-lattice paper boards. The method comprises the following steps that (1) a slope surface is cleaned; (2) the multi-lattice paper boards are prepared; (3) multi-lattice repair paper boards are designed and matched; (4) the multi-lattice repair paper boards with different lattice body depths are cut; (5) the multi-lattice repair paper boards with different lattice body depths are installed; (6) substrates are filled in each lattice body of each multi-lattice repair paper board, and then, grass seeds or turfs are paved, so that the slope surface is flat and smooth. A multi-lattice paper board restoration structure comprises the multi-lattice paper boards with different depths; each multi-lattice repair paper board consists of lattice bodies with different depths, and the multi-lattice repair paper boards are fixedly arranged in each mesh of an outwards exposed net piece covered by an uncovered slope surface. The method for repairing the slope ecological protection base material by the multi-lattice paper boards and the multi-lattice paper board restoration structure provided by the invention have the advantages that the problems of poor protection effects and difficult water and soil conservation can be solved, the intensity is high, the soil can be better held, and the slope surface maintains the flat and smooth condition after the repair.
