中文摘要	岷江上游褐土垂直分布带幅为500～800m,阳坡宽,阴坡窄,粘化层中粘粒(<0.001mm)含量为9％～21％,粘化作用较国内外其它褐土弱,约少1/3～2/3。矿物风化度低,粘土矿物组成以伊利石,绿泥石为主。土壤发育具淋溶和次生粘化特点。根据碳酸盐淋溶淀积强度,可划分为燥褐土、石灰性褐土、淋溶褐土3类型。其淋溶强弱依次为燥褐土<石灰性褐土<淋溶褐土。
英文摘要	The following results were obtained in a study on the genetic characteristics of drab soils.The vertical distribution width of drab soils in the upper reaches of the Mingjiang River ranges from 500 to 800 m,wider on the south slope than on the north slope,exhib- iting a distinct slope-oriented effect.In contrast to the drab soils in other parts of China and in the world,the drab soils in this region are characterized by a weak clayization,con- taining 9—21% clays(<0.01 mm)in their argillic horizon,viz.1/3 to 2/3 less than in other parts.Their mineral weathering degree is relatively low and the clay minerals are mainly composed of illite,chlorite and kaolinite.Soil development shows the characteristics of leaching and secondary clayization.Based on the leaching and deposition intensity of carbonate,the drab soils on this region are divided into three types:dry,calearcous and leaching.Their leaching intensity appears in the order of dry drab soil
