To bring“ wetland” advantage into full play by establishing“ green kidney” which is as important as“ green lung”; set up green“ time channel” by using pluralistic“ cultural meaning” of green space; realize the goal of“ introducing nature into city” with the ecological theory“ climax community”; use the existing laws and regulations on the guaranty of raising the green space to a new stage.
