The invention provides a farmland ecology landscape system. The system at least comprises farmland and field ditches, wherein the field ditches comprise perimeter ditches and internal ditches, the perimeter ditches surround the farmland, the internal ditches are located inside the farmland, ecological plates and slope protection vegetation zones are arranged on the slope surfaces of the two sidesof each field ditch from bottom to top in sequence, and the field ditches are internally provided with aquatic plants and amphibians and/or aquatic animals; the field ditches are communicated with oneanother; the farmland is partitioned into several ridge pieces through the internal ditches; green belts are arranged around the perimeter ditches, and surround the perimeter ditches; several tractor-ploughing bridges are arranged on the field ditches, so that communication among the ridge pieces and communication between the ridge pieces and an external tractor-ploughing path are achieved; waterpurification units are arranged in the perimeter ditches. The system is reasonable in layout, convenient to use, efficient, capable of saving energy and attractive.
