The invention belongs to the technical field of agriculture, and particularly relates to a method for reducing water and soil loss of forest land by storing water through a bamboo basket. The method comprises the following technical measures that 1, when bamboo is cut, the top surface of the bamboo basket is made to be higher than the ground surface of the forest land; 2, a bamboo partition, an inner wall wax layer and an inner spring are broken through; 3, a notch is formed in the top surface of the bamboo basket through cutting and enabled to face the slop top. According to the method, the water and soil loss of the forest land can be effectively reduced, collected ground surface runoff is collected and preserved, and the bamboo basket can be easily removed while the bamboo basket is utilized.
