Litter Production and Nutrient Contents of Litterfall in Oak and Pine Forests at Mt. Worak National Park

Litter production, nutrient contents of each component of litterfall and amount of nutrients returnedto forest floor via Quercus mongolica, Quercus variabilis and Pinus densiflora forests at Mt. Worak National Park. Total amount of litterfal during one year in Q. mongolica, Q. variabilis and P. densiflora forests was 542.7, 459.2 and 306.9 g m-2 yr-1, respectively. Of the total litterfall, leaf litter, branch and bark, reproductive organ and the others occupied 50.3%, 22.7%, 10.1% and 16.9% in Q. mongolica forest, 81.9%, 7.2%, 3.1% and 7.9% in Q. variabilis forest, 57.4%, 12.8%, 5.6% and 24.1% in P. densiflora forest, respectively. Nutrients concentrations in oak litterfall were higher than those eaf litterfall were 13.8, 1.1, 7.2, 4.2 and 1.3 mg/g for Q. mongolica forest, 10.5, 0.7, 3.2, 3.7 and 1.6 mg/g for Q. variabilis forest, 5.3, 0.4, 1.2, 2.8 and 0.6 mg/g for P. densiflora forest, respectively. The amount of annual input of N, P, K, Ca and Mg to the forest floor via litterfall was 43.36, 2.89, 21.38, 23.31 and 5.62 kg ha-1 yr-1for Q. mongolica forest, 32.28, 2.01, 10.23, 20.29 and 7.78 kg ha-1 yr-1 for Q. variabilis forest, 15.80, 1.04, 3.99, 9.70 and 2.10 kg ha-1 yr-1for P. densiflora forest, respectively.
