Abstract
- To develop accurate and predictive global carbon cycle models, it isimportant to understand the change of accumulated carbon for many ecosystemsorganic matter contents through an aerial photo and field observation. As a result,accumulated organic matter contents per unit area (kg m-2) of three communitiescomposed at grassland were 7.00 kgm-2 in Solidago altissima community, 9.18 kg m-2 inImperata cylindrica community, and 12.68 kg m-2 in Miscanthus sinensis community,respectively. Accumulated total organic matter contents was high in Miscanthussinensis community at later succession stage but soil carbon was low. In Miscanthussinensis community, highly accumulated organic matter contents was resulted fromincreasing of biomass comparison with that of the other two communities. The patternof accumulated organic matter contents was changed by changing of the dominantcommunity due to progressing in succession. The accumulated carbon in temperategrassland will be increased with progressing in succession.
