| 摘 要(英文)：Soil respiration (heterotropic and autotropic respiration, Rg) and aboveground litter fall carbon were measured at three forests at different succession (early, middle and advanced) stages in Dinghushan Biosphere Reserve, Southern China. It was found that the soil respiration increases exponentially with soil temperature at 5 cm depth (Ts) according to the relation Rg5a exp(bTs), and the more advanced forest community during succession has a higher value of a because of higher litter carbon input than the forests at early or middle succession stages. It was also found that the monthly soil
respiration is linearly correlated with the aboveground litter carbon input of the previous month. Using measurements of aboveground litter and soil respiration, the net primary
productions (NPPs) of three forests were estimated using nonlinear inversion. They are 475, 678 and 1148 gCm-2 yr-1 for the Masson pine forest (MPF), coniferous and broadleaf mixed forest (MF) and subtropical monsoon evergreen broad-leaf forest (MEBF),respectively, in year 2003/2004, of which 54%, 37% and 62% are belowground NPP for
those three respective forests if no change in live plant biomass is assumed. After taking account of the decrease in live plant biomass, we estimated the NPP of the subtropical MEBF is 970 gCm-2 yr-1 in year 2003/2004. Total amount of carbon allocated below ground for plant roots is 388 gCm-2 yr-1 for the MPF, 504 gCm-2 yr-1 for the coniferous and broad-leaf MF and 1254 gCm-2 yr-1 for the subtropical MEBF in 2003/2004. Our results support the hypothesis that the amount of carbon allocation belowground increases during forest succession. |
