Vegetation bags, artificial bush sand piles, sand blocking and fixing belt and construction method and application thereof

The invention discloses vegetation bags, artificial bush sand piles, a sand blocking and fixing belt and a construction method and application thereof. The method for establishing the sand blocking and fixing belt of the bush sand piles based on the vegetation bags comprises the following steps that soil is taken locally and piled into conical mounds; a plurality of vegetation bags are neatly stacked on the surfaces of the conical mounds along contour lines; sand fixing bushes are planted in all the vegetation bags to form the artificial bush sand piles; and a plurality of artificial bush sandpiles are arranged in multiple rows in a delta shape to form the sand blocking and fixing belt. According to the method for establishing the sand blocking and fixing belt based on the vegetation bags, the forming process of the bush sand piles is shortened to one year from several years to dozens of years in the nature; and meanwhile, due to the fact that the bush sand piles have the good water storage and conservation c
