The utility model discloses an ecological clean system of cities and towns irrigation canals and ditches, including the irrigation canals and ditches main part, the irrigation canals and ditches bottom is from up setting gradually bed course, matrix layer, adsorbed layer down to plant benthophyte in the matrix layer, set up honeycomb type grass planting net on the wall of irrigation canals and ditches both sides, pack planting soil in the grass planting check, plant emerged plant on planting soil, introduce the aquatic animal in the irrigation canals and ditches, perfect irrigation canals and ditches ecosystem food chain. Through combined effect such as aquatic plant, microorganism and adsorbed layers, the interception, adsorb and the degradation comes from nitrogen phosphorus nutrition salt, heavy metal and the organic matter among domestic sewage, farmland drainage, the industrial waste water, has improved traditional irrigation canals and ditches to the purifying effect of sewage, and this ecological ditch
