The invention relates to an ecological slope and an anchor rod strengthening system thereof. The anchor rod strengthening system comprises an anchor rod assembly and an anchoring assembly, wherein the anchor rod assembly is anchored in an anchor rod hole formed in the slope, and the anchoring assembly is borne on the slope surface of the slope; one end of the anchor rod assembly is fixed to the anchoring assembly to form anchoring supporting for the slope; the anchor rod assembly comprises a plurality of anchor rod bodies and connectors used for connecting adjacent anchor rod bodies; due to the fact that the anchor rod assembly is anchored in the anchor rod hole, and one end of the anchor rod assembly is fixed to the anchoring assembly, an integrated structure is formed by the anchor rod assembly, the anchoring assembly and the slope, and supporting and strengthening for the slope are realized; and due to the fact that the anchor rod bodies for supporting the slope are connected by the connectors, not only is connecting quick, but also transporting of heavy welding equipment to a construction site is not required, the construction process is more convenient, and direct welding the anchor rod bodies on the slope is avoided, and occurrence of the phenomenon of forest fire caused by welding operation is reduced.
