| 摘 要： | 本文在全国系统分类所要求的统一研究方法和测试分析手段的基础上,对我国北亚热带地区中部黄土母质发育的黄棕壤和黄褐土的粘粒特性及矿物学特性进行了分析研究。结果表明:供试上壤粘粒含量高.有明显的层次分异;粘粒化学组成的剖面变异较小,粘粒硅铝率和粘粒硅铁铝率相对一致;土壤粘土矿物组成以2∶1型伊利石为主,并且均含有一定量的高岭石,蒙脱石含量很少,部分土壤含有一定量的蛭石等14(?)矿物;供试土壤上述粘粒及矿物学特性,除受黄土母质本身特性的影响外,还取决于该区成土条件的影响。

| Abstract: | According to the demand of soil taxonomic classification,results obtained fromthis study are as follows:Under the influences of parent material characteristics and the soil forming condi-tions,(1)these soil clay contents are over 30% and distinct in different profilehorizons;(2)there are only slight changes in the chemical composition,SiO_2/Al_2O_3 and SiO_2/R_2O_3 of clay between profiles;(3)illite is dominant in claymineral components of the soils,its relative content is over 40% and all the soils containsome kaolite and less montmorillonid,some of the soils contain some vermiculite orother 14(?) minerals. |
