This paper is a report on the studies on the biomass and litter fall of A.glauca community in artificial stand in Xiamen.
1. The biomass of 5-year-old A. glauca comm. is 81.0t/ha, and the average net productivity is 16.2t/ha·a. Its solar radiant efficient is 0.56%. The extinction coefficient of the stand in autumn is 0.52. This biomass can be expressed by the regression equation as W =a+bD+cD2 in which W is the theoretical biomass; D is the basal diameter;a, b, and c are constants.
2. The annual litter fall in 5-year-old A. glauca comm. is 7.88 t/ha. The content of the major elements in the falling leaves of A. glauca is (kg/ha·a) 152.1 for N, 32.3 for P, and 26.0 for K, and is higher than those in Pinus massoniana and Acacia confusa locally. The decomposite efficiency of the litter fall is fast.
