Abstract: Based on small catchment experiment, the accumulation, distribution and biological and geochemical cycling of mineral elements in Dahurian larch plantation ecosystem are analyzed. The annual uptake of elements is 203.842kg穐a-1, annual return is 60% of the annual uptake (124.334kg穐a-1), and average cyclic coefficient of macroelements including N, P, K, Ca, Mg is 0.607. The nutrient budget indicates that the total input of nine elements from precipitation is 31,928kg穐a-1穣r-1, and output in runoff is 19.832kg穐a-1穣r-1, and the net accumulation in larch forest ecosystem is 12.104kg穐a-1穣r-1, equivalent to 37.9% of the total input. Compared with the geochemical cycling of mineral elements, the biological cycling is characterized by stronger intensity and higher speed.
