The utility model discloses a composite type near-natural governance river bank ecological buffer zone which comprises a buffer zone body, the buffer zone body sequentially comprises a first pebble ditch, a tree and grass plant area, a water and soil conservation grass irrigation landscape area, a second pebble ditch and an aquatic plant purification area from a bank slope to a water body, and thebuffer zone body with the function of resisting and controlling non-point source pollution and landscape benefits is formed. Through layer-by-layer filtering of the first pebble ditch, the arbor andgrass plant area, the water and soil conservation and grass irrigation landscape area, the second pebble ditch and the aquatic plant purification area, farmland and rainwater runoff is effectively purified and permeated and accumulated, most buffer zones are plant combinations, operation and maintenance are easy, the manufacturing cost is low, operability is high, and a damaged bank slope is repaired through disturbance to
