摘要
新源县野苹果林下土壤形成过程主要有腐殖质化过程、粘化过程、钙化过程．土壤风化程度低，粘土矿物以伊犁石为主，粘粒为３．０３—３、１６．为３．９８—４．１６．Ｒ２Ｏ３沿剖面无明显移动．均腐殖质性．Ｒｈ＝０．３３．Ｃ／Ｈ为１１．１—１１．６．为１．５２—２．１３，Ｅ４值２．４０—２．６２．土壤分类学上属于均腐殖质土纲．
The main genetic processes of soil urder wild-apple forest in xinyuar county include humification,argillization, calcification. The soils is weak in weatheving, and have the clay minerals being dominated by illite, SiO2/R2O3 is 3. 0～33. 16, SiO2/Al2O3 is 3. 90～4. 16, and these is no evident movement of R2O3 along the section. The even humic property, R/2 is 0. 33, C/N is 11. 1～11. 6, is 1. 52～2. 13, the value of E4is 2. 40～2. 62. Taxonmically it belongs to even homic order.
