| 摘 要： | 对四川盆地西部丘陵地区分布的几种黄色母质发育的土壤，以系统分类的原理和方法进行了分类，并与现有发生学分类进行参比，代表性剖面研究结果表明，这些土壤分别被划归富铁土、淋溶土和雏形土等3个土纲。分类系统更科学和完善。

| Abstract: | Such types of loesses as aeolian Chengdu Clay, sedimentary Guanghan Clay, and alluvial Ya'an Clay with a horizon of gravels, distributed in hilly region of western Sichuan Basin. The properties and classification of soils developed from loesses depends deeply on the features of those loesses. The results showed that soils derived from different types of loesses varied apparently in mechanic composition, pH, content of CaCO 3, CEC, etc. By analyzing representative soil profiles, the diagnostic horizons and diagnostic characteristics to classify those soils had been established, based on principles and methods of soil taxonomic classification, and in particular Truncated property was suggested at first time, which hadn't been quantified yet. The taxonomic classification of soils developed from loesses had been proposed also, and refereed with genetic classification. |
