摘    要:以土壤组合的个体单元为研究对象,根据梁滩河流域自然环境的基本结构特征,讨论了不同地貌条件下土壤组合单元的形成与发生机制。认为在川东丘陵区,土壤组合单元的发生主要受地貌形态的制约,物质、形态、能量、时间是土壤组合单元形成与分异的四大基本要素。

关 键 词:川东丘陵区  土被组合单元  土壤结构  土壤发生学

Abstract:This paper studied the soil association unit genesis of a small synctinal basin,the Liangtanhebasin,in the middle part of the paralled ridge-valley area in East Sichan,by selecting some essential landform units as the floodplain, the genter-hill plain, the mesa and the cuesta where some soil associa-tion units are occured ,The paper also deals with their occurence progresses and features. It suggests that there are four essential elements to control the soil association units occurence. Those elements arecalled matter ,energy , landform and time in which the landform is the most important factor in the ar-eas.
Keywords:hill area in East SiChuan  soil association unit  soil mantle structure  soil genesis
