Statistics Analysis on Dynamical Sampling Data of Plants in Growing Season

摘要：

Based on statistics analysis, four representative plants were chosen in different degenerated steps in Leymus chinensis + Stipa grandis in the typical steppe of Inner Mongolia. They were Leymus chinensis, Stipa grandis, Agropyron michnoi, Artemisia frigida. The surveyed data of four plants in one growing season was analyzed and verified. The results showed that the individual plant biomass (dry matter) in one sampling day satisfied the Normal distribution; it was proved that the statistics biomass of 100 samples in one sampling day can be replaced by that of 50 samples in the fiducially level over 95 percent.
