The invention relates to an ecological planting pool and an ecological septic system, and belongs to the technical field of sewage treatment. The ecological planting pool comprises a pool body, a water inlet and a water outlet, wherein the water inlet and the water outlet are formed in the pool body. A packing layer, a filter layer and a planting layer are sequentially arranged in the pool body from bottom to top. A glass fiber cloth layer is arranged between the filter layer and the packing layer. The pool body comprises a pool wall and a pool bottom. The water inlet is formed in the position, corresponding to the packing layer, of the pool wall. The water outlet is formed in the position, corresponding to the filter layer, of the pool wall. According to the ecological planting pool, large solid particles are intercepted through the packing layer on the lower portion, the plant planted on the upper layer is prevented from being polluted, the solid particle can be buried in the deep layer to continue to be fermented, the step-by-step filter effect is formed from bottom to top, and the sewage treatment effect is high.
