摘要: 长白山位于吉林省东南部与朝鲜交界处,海拔2700余米,为亚洲大陆东北部之高峰,亚洲东部苔原分布的南界,也是我国东部唯一出现高山苔原的地方。在长白山土壤垂直分布系列中,对山顶无林带土壤的命名,以往曾有人称山地石质草甸土、高山草甸土、高山冰沼土、山地冰沼土等。

Abstract: The Changbai Mountain which is situated at the boundary between the southeastern part of Jilin province of China and Korea,is the highest peak inthe northeastern part of Asia and it is also the sole mountain in eastern China developing tundra soil.The characteristics of the alpine tundra soil on the Changbai Mountain areas follows:(1)The accumulation of organic matter is obviously faster than the deco-mposition of organic matter.(2)The soil solution pH 4.9-6.1.The reaction in the layer not far from the surface layer is mainly reduction and strong gleization dominantly takes placeand furrous oxides are formed.(3)The soil layer is thin.Its texture is coarse.Its exchange able base content is very low(<10m·e/100g soil).And it is deficient in nutritious elements.(4)In the humic composition of soil,fulvic acid is dominant,except inpeat layer (H/F0.24-0.82).The alpine tundra soil of the Changbai Mountain is divided into 3 sub-groups:1.original or stony tundra soil;2.typical tundra soil;and 3.bush tundra soil.
