DYNAMIC DETERMINATION REPORT OF FORAGE YIELD IN TONGREN CRASSLAND

By using the representative and timing sample, we have continually inspected the natural meadow in Tongren County for 5 years. The result shows: in 1996 and 1997, the yielding quantity of grass is high in the whole county and the proportion of grass and livestock is basically balanced; however, during 1998, 1999and 2000, the yield of grass is obviously declined and the grassland is overloaded. Especially in the year of 2000, the contradiction between grass and livestock appears prominently and the ratio of overloading is up to 60%.
