内容記述 | The soil solutions in surface peat soils were collected by using four methods : the peatland water method (PW), by which the seepage water in a pit of peatland was collected, then porous cup method with suction (PC), the centrifugation method (CF), and the water extraction method (WE). Each collecting method was repeated 4 times in a square section (2 m × 2 m) under the same vegetation. Two peatlands developed around the coastal area at the Pacific seaboard of eastern Hokkaido were selected in this study. The aquatic quality and inorganic ion concentration in the soil solutions were analyzed, and their coefficients of variation (CV) and their relation to the properties of peat samples were examined. 1) The physico-chemical properties of peat samples collected from four sites in each square section were not different significantly, while the aquatic qualities and inorganic ion concentration of soil solution samples in the same sections were considerably different among the sampling methods.
