Abstract

Forms and accumulation of soil phosphorus (P) were measured in a subalpine quaking peatland on Mt. Changbai in China that is located 1 km from the North Korea border. Peat cores were collected from 4 sites and radiometrically dated to determine long-term (210Pb-based) rates of peat and P accumulation. Soil P forms at different depths in 4 peat cores were determined by a modified Hedley fraction method. High rate of peat accumulation in the Yuanchi peatland was found. High values of organic phosphorus forms exist in the minerotrophic fens. Compared with other peatlands, the accumulation of total phosphorus in the Yuanchi peatland was higher, suggesting that the volcanic parent material had an influence on P accumulation
