Gully ecological restoration treatment method for lake-entering water source of plateau lake

The invention provides a gully ecological restoration and treatment method for a plateau lake inflow water source, a brush reduction ridge, an ecological storage and stagnation pool and a vegetation treatment zone are sequentially arranged at the downstream section of a gully, and first retaining walls are arranged between the brush reduction ridge and the ecological storage and stagnation pool and between the ecological storage and stagnation pool and the vegetation treatment zone. Ecological restoration is conducted on the periphery of the gully in an upper-cutting, middle-dredging and lower-discharging mode, namely, a brushing-reducing ridge is arranged on the upper portion of the downstream of the gully, an ecological storage and stagnation pool is arranged in the middle of the downstream of the gully, and a vegetation control zone is arranged on the lower portion of the downstream of the gully; the ecological storage pond perfects a biological retention system, fixes soil and water, and purifies surface
