Water loss and soil erosion measurement device

The invention discloses a water loss and soil erosion measurement device. A bottom hole (4) is formed in the bottom of a soil container (1); a flange (5) is arranged at the edge of the top of the soil container (1); an edge hole (6) is formed in one side of the top of the side wall of the soil container (1); the interior of a bottom collector (2) is divided into at least two independent compartments (7); a convex edge (8) is arranged at the edge of the top of the bottom collector (2); the bottom collector (2) is connected to the lower side of the soil container (1); an external collection tank (3) is connected to the bottom side wall of the bottom collector (2) and corresponds to the edge hole (6) in the soil container (1). The water loss and soil erosion measurement device can comprehensively detect the water loss and soil erosion situation above and under the ground simultaneously, so that a monitoring result of water loss and soil erosion can better meet the actual water loss and soil erosion; the water loss and soil erosion measurement device is simple in structure and easy and convenient to operate, and is more convenient and direct to observe; the workload of a worker can be greatly reduced, and the water loss and soil erosion measurement device has outstanding practical significance.
