    摘要:

    本文对第四纪红土发育的土壤的研究结果表明:在我国亚热带范围内,地带性因素对土壤性质的影响在一定程度上是客观存在,但有局限性;母质等地域性因素对土壤性质的影响常常会超过地带性因素的影响;第四纪红土的物质来源受周围岩性和黄土的影响,与下伏砂岩不一定有必然的联系;风化程度在剖面中的变化是气候变迁的标志之一。

    Abstract:

    Fourteen profiles from humid subtropical region were investigated using physical, ehemical, and mineralogical techniques. The results showed that zonality factors had impacts on soil properties to some extent within subtropical region, however, the factors like parent material were also important, its influences on properties such as CEC, iron free degree of clay were greater than that of bioclimate; Quaternary red earth was not the weathering products of the sandstone underlain but influenced by surrounding rocks or loess based on the particle size distributinn pattern and heavy mineral associations; while the decrease of weathering degree from bouom in surface in the profile was the result of climate changes from humid and warm to mild.
