Fine Root Decomposition Dynamics in Moso Bamboo Forest of Southeast China

Abstract:

To provide an important basis for the biogeochemical cycle of bamboo forest ecosystem, particularly the cycling of carbon, we studied decomposition dynamics of fine root in moso bamboo forest. Our study area located in Miaoshanwu nature reserve, Fuyang, Zhejiang province. Based on our study, we concluded: (1) the process of bamboo fine root with diameter less than 2mm and within 2-5mm can be modeled with Olson Decomposition Exponential Model. It showed that decomposition for fine root with thinner diameter is faster than that with thicker diameter.(2) The mass loss for the fine root with less than 2mm diameter and within 2-5mm diameter is 41.30% and 37.64% after half-year decomposition respectively, 62.61% and 56.27% after one year decomposition respectively.(3) It takes 8.13 months and 9.75 months respectively for 50% mass loss and 38.77 months and 48.36 months for 95% mass loss respectively for the two diameter classes of fine root.
