| Research Abstract |
This study consists of the following three sub-themes : 1) quantitative evaluation of temporal variability of carbon cycle parameters along with secondary succession ; 2) examination of sustainable carbon sequestration within developing ecosystems in terms of a succession/carbon dynamics model ; 3) temporal variation of soil organic carbon with primary succession. Our chronosequence study of secondary succession in Sugadaira, Nagano prefecture, used for the following ecosystem sequence : Artemisia-dominant grassland, Miscanthus-dominant grassland, Populus-dominant forest, Pinus-dominant forest, Quercus-dominant forest and Fagus-dominant forest. Carbon sequestration within the plants increased with succession. However, litter carbon showed no increase or decrease with succession. Soil carbon increased in herbaceous sere, and decreased in early forest stages. Thus, our results demonstrated that secondary succession influenced the size of carbon pools within the ecosystems. The measured results were confirmed by a simulation in terms of a succession/carbon dynamics model. In primary succession study (Miyakejima study site), soil organic carbon increased from a naked land to a climax stage.
