摘　　要：根据长江中下游三个下蜀土剖面94个样品主要组分元素化学成分的分析结果,结合西北洛川黄土数据资料进行了下蜀土剖面主要元素成分含量和风化程度的分析对比。结果表明不同下蜀土剖面在主要组分含量上差异不明显,但在易淋溶元素含量和经历的化学风化程度方面存在一定差异。This paper reports the analytical results of major chemical components of 94 loess samples from the Xiashu loess profile in the middle and lower reaches of the Changjiang River, the major component contents and the weathering intensity of Xiashu loess were compared with those of Luochuan loess from Northwest China. The results show no obvious difference in the contents of major components in the different Xiashu loess profiles, but some difference in the contents of readily leaching elements of loess and the chemical weathering intensity of loess among the different Xiashu loess profiles.
