The invention discloses a vegetation type anchor rod ecological bag and a slope protection method thereof. The method comprises the first step of construction preparing, the second step of measuring and lofting, the third step of base cleaning and leveling, the fourth step of ecological bag filling and mixing, the fifth step of ecological bag packing, the sixth step of slope body earthwork backfilling, the seventh step of slope ratio determining through wire pulling, the eighth step of ecological bag building, the ninth step of slope face cleaning, the tenth step of afforest constructing, and the eleventh step of maintaining. According to the vegetation type anchor rod ecological bag, water is allowed to seep out of a bag body, the hydrostatic pressure of the bag body is reduced, the soil in the bag is not allowed to get out of the bag body, the purpose of conservation of water and soil is achieved, the bag body becomes a medium for the survival of plants, and the bag body is soft and good in integrity. An anchor rod connecting assembly is adopted, the whole bag is subjected to the force, the vegetation type anchor rod ecological bag has scientific stability, and the construction method is simple and convenient. The vegetation type anchor rod ecological bag has high adaptability to the environment, the environment can be beautified after construction, air can be purified, the vision fatigue is relieved, and the vegetation type anchor rod ecological bag is integrated with the nature.
