The invention discloses an anchoring material for landslide geological disaster control and a preparation method thereof. The anchoring material for landslide geological disaster control comprises a carbon fiber composite material and a steel bar material. The carbon fiber composite material is prepared from polyacrylonitrile-based carbon fibers and asphalt-based carbon fibers according to the weight ratio of 1:3.0-5.0. The asphalt-based carbon fibers are prepared from petroleum asphalt and coal asphalt according to the weight ratio of 0.8-1.2:1. The weight ratio of the carbon fiber composite material to the steel bar material is 1:4.0-6.0. The anchoring material is low in cost, low in weight, high in strength and resistant to corrosion; compared with existing materials, the anchoring material is more suitable for landslide geological disaster control.
