According to the steep-slope buffer strip gradient treatment system achieving rain runoff collection and purification and the construction method, the gradient ecological hedges and the aquatic plant functional zone are arranged, and the slope drop of the steep-slope rain runoff is retarded; by means of diversity configuration of plants with deep and shallow roots, a dam is fixed, and the silt is blocked; by means of the multistage ecological filters, the rain runoff retention time is prolonged, the water storage rate and the infiltration rate are increased, and the water purification efficiency is improved.
