新疆阿尔泰山西北部山区针叶林下土壤的形成特征

GENETIC CHARACTERISTICS OF SOILS UNDER CONIFEROUS FOREST IN NORTH WESTERN PART OF ALTAI MOUNTAINS

本文研究了新疆阿尔泰山西北部山区针叶林下土壤的形成特征，并与我国东部地区的灰化土、暗棕壤进行对比，认为林下土壤与灰化土、暗棕壤有明显的差异，冷凉湿润的水热状况和发育的季节性冻层对于土壤的形成具有重要作用，宜将林下土壤定名为寒棕壤。

The genetic characterishcs of the soils under coniferous forest in the north western part of Altai Mountains were studied in comparison the podzolic soil and dark brown soil in the eastem part of China. There exists distinct difference between the soils under the coniferous forest and the podzolic soild and dark brown soil. The frigid and moist hydrothermal condihon and seasonal freezing layer have important effect on the characterishcs of the soil. So the soils under the forest should be called cold brown soil (brown coniferous forest soil).
