The invention discloses a channel reservoir hydro-fluctuation belt vegetation recovery method. The channel reservoir hydro-fluctuation belt vegetation recovery method comprises the following steps that in a target vegetation recovery area, planting holes are dug; a streamline flow guide weir is arranged on the upstream side of the planting holes; the planting holes are distributed in an array, andthe planting holes are connected through shallow grooves; the roots of flooding-tolerant suffruticosa plants are bundled with living willow branches or other plant branches into planting bundles; theplanting bundles are inserted into the planting holes; planting soil slurry is poured into the panting holes. By means of the method, it is achieved that vegetation is planted on a bed rock substrateof a reservoir hydro-fluctuation belt, the flow guide weir can reduce the impact of water flow to plants, the shallow grooves between the holes can help the roots of the plants communicated into a network, the plant adhesion capacity is enhanced, and rainwater is easily collected to be converged into the planting holes; the planting bundles bundled with the living willow branches can serve as plant propagules so as to increase the green quantity and enrich the biological diversity, and the planting bundles bundled with other plant branches can continuously provide nutrients for the suffruticosa growth in the slow decomposition process.
