摘    要:本文运用美国土壤系统分类原则和方法,研究了分布于山东半岛一带和河南南阳盆地的六个土壤剖面的发生特征和分类。供试土壤的割面单一体化明显,为A-C土体构型。土壤粘粒含量高,且富含蒙脱石类粘土矿物,线性膨胀系数大于0.1。割面中多交叉状裂隙和楔形结构体,有滑擦面和应力胶膜。盐基高度饱和。有机质含量不高。氮、磷含量低。这些土壤划归变性土土纲、半旱变性土亚纲,文中还有亚纲以下各级分类和命名。

关 键 词:单一体化  滑擦面  楔形结构体  半旱变性土

Abstract:Investigation on genesis and classification of six dark calyey soils from Shandong, Henan and Hubei provinces showed the considerable similarities in morphology, property, development and category of these soils to Vertisols. Some basic diagnostic properties for Vertisols, such as heavy texture (loamy clay to clay), predominantly montmorillonitic clay minerals (content 40% in general), high cole values, cracks, wedgeshapes natural structure aggregates and slickensides were all found from six soil profiles. The taxondmic classes and families of the Vertisols were identified basically by the "soil taxonomy". Most of the Vertisols studied were chromusterts and pellusterts.
Keywords:Slickensides  Wedge-shapes structure  Chromusterts  Pellusterts
