Abstract: A kind of falling-plate meter made in New Zealand was used to estimate the pasture yield of an enclosed subalpine meadow. The relationship between compressed sward height and pasture yields was analyzed and the estimation model was established. The results showed that there were close correlation relationships between compressed sward height and pasture yield, and the estimated value of pasture yields were significantly related with the measured value. It was indicated that the device of the falling-plate meter could be used to estimate the pasture yield in enclosed subalpine meadow with high efficiency.
