The invention relates to the technical field of pipeline protection, and discloses an ecological protection system suitable for a stone channel region pipeline. The ecological protection system comprises a matrix layer, a buffer layer, a transition layer, a root blocking layer and a rock ballast backfill layer which are sequentially arranged from top to bottom, and the pipeline is buried in the rock ballast backfill layer; the matrix layer comprises a matrix particle material and rock ballast; the buffer layer comprises rock ballast, attapulgite, peat, super absorbent resin and polyacrylamide;the transition layer comprises rock ballast and bacillus dregs; and the root blocking layer is prepared from acrylate emulsion, copper sulfate powder, leucaena leucocephala extracting solution and vermiculite. According to the ecological protection system, the comprehensive protection function of a plant system can be utilized, the phenomena of water erosion and collapse after pipeline landfill are reduced, the external impact force and the damage effect of plant root systems on the pipeline are reduced, and therefore the pipeline can be continuously and stably protected under the condition of no management and protection, and the plant survival rate can be increased.
