The contents of nutrition elements in different organs of tree, rattan and litter vary in different species for specific element. The total amount of the tested 10 elements are 1 977.78, 2 142.54, 1778.21 and 989.36 kg/ha respectively for the types I to IV, among them, 82%~90% distributed in the tree layer, 4%~6.5% in rattan, and 5%~12% in litter compared with the distribution of biomass, rattan and litter have higher percentages in nutrition contents. The amount of nutrition elements required for an unit dry matter production and the ratio of nutrition returning back to the soil vary in different types of stands. In type I to V, the total amount of the 10 nutrition elements required for producing a ton of dry matter is 11.999,12.999,10.449,10.008 and 23.974 kg/ha respectively. The ratio of nutrition elements returning to the soil is 30.3%, 39.3%,30.3%, 54.4% and 92.1% respectively.
