The present invention relates to an. The ecological greening wall comprises a plurality of fixing posts stood on the ground and arranged at interval, wherein reinforcements with holes are fixedly fixed among the fixing posts, and are vertically arranged along the fixing posts; planting bags for planting and greening are piled on at least one side in two sides of each reinforcement; the planting bags comprises air and pervious bag bodies and plant growth material filled in the air and pervious bag bodies; and the air and pervious bag bodies and the reinforcements are fixedly connected by reinforcement wall bodies to enable concrete wall bodies, the reinforcements and the planting bags to form a whole body. Thus, the planting bags are used for greening to form the ecological greening wall having the advantages of simple structure, stable entirety, heat and sound insulation and easy construction. The ecological greening wall has a greening and environmental function, and can be widely applied to the aspects of sound insulating walls on house base walls, highway insulation belts, guiderails on two sides and viaducts, and the like.
