碩士 === 國立屏東科技大學 === 水土保持系所 === 103 === This study investigated the landslide of different years of soil carbon storages in southern Taiwan.Collection five soil pedons and litter of different years landslide. The results indicate, the soil carbon storages is lowest in landslide of 2009 year, because soil depth less than 30 cm, the results indicate 0.3 kg C 30cm-1 m-2 and carbon pool is highest in landslide scar of 1963 year, 3.4 kg C 30cm-1 m-2，5.2 kg C 50cm-1 m-2 and 12.2 kg C m-1 m-2. The carbon pool of 1974 and 1989 years are secondly. The carbon pool of litter, these data that the accumulating SOC contributed from different litter. The carbon pool is also negatively related to soil pH value of landslide scar soil (P<0.0001). About 20% of carbon pool was stored in upper 30cm, about 30% of carbon pool was stored in upper 50cm and 50% of carbon pool was stored in upper 50cm to one meter. The results, the soil carbon of landslide scars in 1974 and 1963 years than unperturbed, the soil carbon of landslide scar in 1989 year less than unperturbed. Apart from time, other environmental factors also have a effect on the accumulation of soil carbon accumulation and distribution. The stands of this still represent soil ecosystem and maybe other environmental factors change soil carbon accumulation and distribution. Effects of major factors that control the formation of soils on soil depth, bulk density and stone percentage result in a large spatial variability of soil carbon storage.
