The invention provides a project integrating functions of walls, fences, wattled walls, guardrails, advertising walls, isolation barriers and gallery frames with greening, landscape, planting, ecology and environmental protection, and should belong to the fields of architecture, landscape, planting, ecological environmental-protection and the like. Afforestation and expansion of urban and rural green coverage are urgent problems to be solved by our society; if tree planting can be used to replace the walls, the fences, the wattled walls, the guardrails, the advertising walls and the highway isolation barriers throughout the urban and rural areas, the urban and rural forest coverage can be increased in large area without occupying other lands; after years of research and adjustment on a planting soil layer, a dense planting method as well as trimming and pruning, fast-growing bamboo willow, salix babylonica and other easily cutting trees are selected, a 'sponge' soil structure is researched and developed, the survival rate is up to 95% or more, and the planting ecological wall, fence, guardrail and isolation gate are the best choices for constructing the urban and rural walls, fences (wattled walls), guardrails, landscape walls, advertising walls and highway isolation barriers, and are the transformation of alternative ways and forms and concepts of traditional walls and fences.
