| 摘 要： | 选取成都金沙遗址揭露的广汉层中一个代表性剖面，对其元素地球化学行为进行了初步研究。结果显示，稀土元素配分型式的相似性，揭示了成壤物质的同源性；元素含量在剖面上部、中部和下部呈规律性变化，反映了成壤过程物质分解、元素迁移和气候变化。 |

| Abstract: | A representative section is chosen in Guanghan layer exposed in the Chengdu Jinsha site in this article, and an initial research into its element geochemical behavior is done. The result shows that the (resemblance) of REE curves reveals the consanguinity of soil matter and the element content in the top, centre and bottom of at the section changes regularly. This reflects matter decomposition, the element (migration) and the climate change in the pedogenetic course. The element characteristics in the soil layer of the Chengdu Jinsha site indicate that it formed in the arid environment. The deposit from Layer 1 to 4 has the same change trend and reflects the modern climate. |
