摘　　要：[Objective] This study was conducted to investigate the eco-geochemical characteristics of corn production area in Inner Mongolia Hetao agricultural economic zone. [Method] Corn root soils and corn samples from various parts were collected from the Inner Mongolia Hetao agricultural economic zone. Trace element contents in root soils and different parts of corn were analyzed. [Result] Most element contents in cumulated irrigated soil were relatively higher. Most elements were relatively enriched in the stems and leaves of corn. F, Mn and Co were relatively enriched in roots of corn; and N was strongly enriched in grains, and Zn and F were relatively enriched in grains. [Conclusion] It is necessary to rationally apply fertilizer in corn production area in Hetao and control the application of harmful elements in fertilizer in future.[目的]研究河套农业经济区玉米产区生态地球化学特征。[方法]通过采集研究区玉米根系土及玉米各部位样品,分析了根系土和玉米各部位地球化学特征。[结果]灌淤土中大部分元素含量相对较高;大多数元素在玉米的茎叶中相对富集;F、Mn、Co元素在根中相对富集;N元素在籽实中强烈富集,Zn、F在籽实中相对较富集。[结论]建议河套地区富F的土壤环境中要采用低F化肥。玉米种植区均需要增加氮肥。对化肥中的各有害元素需进行控制。
