The utility model belongs to the technical field of bridges, and particularly relates to a steel pedestrian bridge with small landscape gates, wherein the steel pedestrian bridge is used for small and medium rivers and channels of urban areas. The steel pedestrian bridge comprises bridge piers and steel structure pedestrian ways erected on the bridge piers. Each steel structure pedestrian way is erected on the tops of every two adjacent bridge piers, the two ends of the steel structure pedestrian way are fixed to the tops of every two adjacent bridge piers respectively, and each overflow flat steel gate is arranged between every two adjacent bridge piers. The steel pedestrian bridge has the advantages that the gate groove sunken arrangement mode that the overflow flat steel gates and the steel pedestrian bridge are combined is adopted, repeated construction of gates and bridges is avoided, urban space and investment of capital construction are saved, the function requirements of conducting water level adjustment and drawing off floodwater are completely met, water is stored in the upstream in the non-flood season to form water area landscapes, base flow overflows to the downstream through the tops of the gates, a waterfall is formed on the tops of the gates, and ecology landscapes and water conservation landscapes are constructed.
