| 内容記述 | The morphological and selected chemical properties of 18 pedons developed in Changbai volcano area, Northeast China were investigated. The parent material of these soils consists of thick and coarse tephra deposits from plinian falls, pyroclastic flows and lahar (mudflow) mainly from the 10th century eruption. Although some buried horizons underlying the thick tephra deposit of the 10th century eruption showed clayey soil texture, these soils are characterized by sandy soil texture, A/C type of soil horizon sequence and low acid oxalate-extractable Al+Fe content. Based on the world reference base for soil resources (WRB : FAO, ISRIC and ISSS, 1998), many horizons met some criteria of vitric horizon, while considerable horizons were tephric soil materials. These suggest that the tephra-derived soils in this area is on a young stage of soil development. The cooler climate condition played a major role in the slow soil development. Furthermore, the parent material consisting of the coarse textured tephras provided by the sequential plinian falls and pyroclastic flows, not fine textured volcanic ash, would affect the slow rate of tephra weathering. The soil genesis of the Changbai volcano area is dependent on the properties of the parent material and different climate conditions with elevation. | |||||||||||
