| Abstract: | This paper deals with biomass, productivity and decomposition dynamics of fine roots in Dendrocalamopsis oldhami forest in South of Fujian province. The results were shown as follows: fine root biomass of Dendrocalamopsis oldhami forest was 9 761 kg/hm 2, annual productivity from the July 1996 year to the June 1997 year was 3 537 kg/hm 2, fine root turnover rate was 0.46 time per year. The decomposition of fine root speed progressively up and half decomposition periods were 230 days. |
