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
