摘  要：
通过对澜沧江自然保护区土壤的研究,认为该保护区土壤包括3个土纲,5个土类,6个亚类。土类垂直地带性明显,赤红壤:800~1300m;红壤:1300~2200m;黄壤:2100~2400m;黄棕壤:2400~3000m;亚高山草甸土:3000~3429m。除亚高山草甸土外,其余土类土层深厚。保护区土壤质地大多为中壤、重壤土,呈酸性或强酸性反应。表层土壤全量养分、速效养分十分丰富。淀积层土壤养分含量差异大,红壤、黄壤淀积层养分含量少,但黄棕壤、亚高山草甸土淀积层养分含量较丰富。

摘  要：
According to the study on the soil of Lancangjiang River Nature Reserve,the soil of the Nature Reserve includes 3 soil classes,5 soil great groups,6 soil subgroups.The zonation of soil in perpendicularity is clear.That is,the vertical distribution range of crimson soil:800-1300m;the vertical distribution range of red soil:1300-2200m;the vertical distribution range of yellow soil:2100-2400m;the vertical distribution range of yellow-brown soil:2400-3000m;the vertical distribution range of subalpine grassy-marsh soil: 3000-3429m.The soil layer of the other soil great groups is deep and thick.The soil textures in the reserve are mainly medium textured soil and heavy loam,and these soils are acid and strongly acid reaction.The total nutrient and effective nutrient of the topsoil layer are all very abundant.The soil nutrient in the sediment layer is different very much.The nutrient capacity of the red soil and yellow soil in sediment layer is less,but the nutrient capacity of the yellow-brown soil and the subalpine grassy-marsh soil in sediment layer is very abundant.
