| 英文摘要 |
| Soil and plant samples were collected from the sunflower growing area in the west of Jilin province. A variety of ancillary methods were used to determine the soil element content.Then the rare earth elements geochemistry in soil was studied,and the correlation of REEs in this region with other elements and the quality of plant was investigated. The results show that, ①REE content of the soil in Nong'an is relatively higher to those in Daan and Tongyu. Distribution pattern of rare earth elements in soil for the right tilt of the light rare earth enrichment patterns which is consistent with the national distribution pattern of rare earth elements; ②REE contents in the three studying areas in the soil are different, and this primarily relates to the soil parent materials; ③The REEs which positively correlate with soil available potassium are Se， Fe2O3， Ti， P， Mn， Cu， Zn， Cr， Mo， B， F. The protein content of sunflower seeds has a negative correlation with REE. With the exception of Lu, all REEs show a similar correlation. |
