The invention belongs to the field of landscape building bricks, specifically discloses a non-slip building block for a slope surface and landscape and a construction method for the non-slip building block. The non-slip building block comprises an upper surface and a lower surface, wherein a plant-growing hole is formed in the position, in the thickness direction of the non-slip building block, of the middle of the upper surface; a plurality of non-slip teeth are arranged on positions, in the width direction of the non-slip building block, of the lower surface; and the non-slip building block has two inclined sections at the top end in the length direction. The construction method for the non-slip building block comprises the following steps of: laying the non-slip building block on the slope surface according to a needed pattern; and planting vegetation on the pattern formed by the non-slip building block and in the plant-growing hole. The non-slip building block is simple in structure, is relatively light in weight, saves material consumption, and is convenient for quick artificial construction; a construction way is flexible, so that a built ecological slope is beautiful in model; and the non-slip building block is good in non-slip effect, and guarantees safety of construction staff.
