The difference and vertical variability of the major nutrition elements contents in Carex lasiocarpa wet land soil and farml and soil are studied. The results show that the major nutrition elements contents inCarex lasiocarpa wet land soil are much more than those in farmland soil (except for to talK content of surface layer)

in which the contents of total P and total N in Carex lasiocarpa wet land soil are twenty more than those in farmland soil. The vartical variability of Carex lasiocarpa wetland soilis no table

more than 40%

in which the variabili ty coef ficient of total N is highest

reaching 81.32% . But the verticality variability of farmland soilis not notable

less than 24%

mostly due to the water condition and the organic matter content.
