The quadrat frame for steppe ecological monitoring comprises a plurality of supporting rods, the supporting rods are arranged in a square shape, every two adjacent supporting rods are connected through a right-angle connecting piece, fixing mechanisms matched with the right-angle connecting pieces are arranged at the two ends of one side of each supporting rod, and clamping grooves are formed in the middles of the two ends of each supporting rod. A plurality of positioning holes are formed in the two sides of the two ends of the supporting rod, and first inserting holes are formed in the two sides of the interior of the clamping groove. The quadrat frame is reasonable and reliable in structure and convenient to operate, the quadrat frame can form a square quadrat frame through cooperation of the multiple supporting rods and the multiple right-angle connecting pieces, it can be guaranteed that the four corners of the quadrat frame are all right angles, and therefore the using effect of the quadrat frame can be
