Abstract

The bioaccumulation of nitrogen and ash of brown soil of desert steppe is different from other soils in Inner Mongolia. The aboveground bioaccumulation of nitrogen is 1.43g/m2, making up 5.01% of the total bioaccumulation,among which the bioaccumulation of Artemisia pectinata is the highest, being 54.32% of the aboveground bioaccumulation. The undergrrond bioaccumulation of nitrogen is 27.14g/m2, amounting to 94.99% of the total bioaccumulation of nitrogen,but the accumulation of nitrogen in 0—30cm is 80.24% of the total underground bioaccumulation. The accumulation of ash shows a similar trend. The total bioaccumulation of ash is 280.69g/m2. The bioaccumulation of underground and aboreground is 95.92% and 4.08% of the total bioaccumulation of ash respectively.
