Through measurements of above-ground biomass production and 10 nutrition elements' accumulation in four types of man-made treerrattan mixed plantations (the age of trees and rattan are 18-year-old and 5-year-old respectively) and a pure plantation of Calamus tetradactylus Hance. The results showed that the total above-ground biomass yield is 164.849,164.844,170.195, 98.864 and 16.234 t/ha respectively for the type I to V; and the biomass of the trees accounts for over 92%,rattan for 2%~4%, and litter for 2%~5% in the tree-rattan plantations. 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.
