新疆阿尔泰山的灰黑土区域性形成性特点的研究

Study On The Genetic And Regiond Features Of The Gray Soil Under The Forests in Xinjiang'S Aerial Mountain Area

新疆阿尔泰山的灰黑土形成过程主要有腐殖质化过程、粘化过程、化学风化过程、生物富集过程等，粘粒硅铝率淋淀比１．１６，硅铝铁率淋淀比１．１７，粘土矿物以伊利石、蒙脱石为主，Ｒ＝０．７７．与我国东部同类土壤比较，区域性形成特点十分显著本文对其分类问题进行了探讨。

The main genetic processes of the gray soil under the forests in xinjiang's Aerial mountain area include hu on, argillication, chemical weatherign. biological returning salt-particle. The proportion of leach and illuvianon of SiO2/Al2O3 is 1.16, and that of SiO2, R2O3 is 1.17, and have the clay minerals heing dominated by iuite and montmorillonite, R is 0.77.The regional features of its genetic characteristics are very obvious as compered with the sim soil in the east of china and inquire into the question of the siol classification.
