| Abstract: | A study on the litterfall in tropical man made forest was carried out at Xiaoliang, Guangdong province from Jan. 1984 to Dec. 1994. The plantation was dominated by Aphanamixis polystachya, Chukrasia tabularis, Acacia auriculiformis, Aquilaria sinensis, Cassia siamea and Albizzia odoratissima . According to investigation data, the annual litterfall averaged 5.539 t/hm 2 and monthly litterfall varied apparent. Greater litterfall took place in raining season with a peak in July. The annual litterfall was getting stable with plantation growing up. The litter had a storage of 4.9 t/hm 2 on the ground. The decomposition rate was greater than the accumilation rate. |
