摘　　要：2002年5月,对东北农牧交错带内某草甸土壤、小尾寒羊主食的羊草、放牧小尾寒羊被毛中含硒量进行了分析。结果表明,该交错带春季土壤中平均含硒量为111.80μkg/kg,羊草中平均含硒量为78.88 μg/kg;放牧小尾寒羊被毛中平均含硒量为420.28μg/kg。据此认为,该交错带春季放牧小尾寒羊不会发生硒缺乏症和硒中毒痛。The selenium contents in soil, Aneurolepidium preferred by codetta and wool of codetta were determined in northeast farming-grazing enterlocking district in May,2002. The results showed that the total average content of selenium was 111. 80 μg/kg in soil, 78.88 μg/kg in Aneurolepidium and 420.28 μg/kg in wool of the grazed codettas. In general, the grazed codetta can not suffer from the disease of selenium deficiency or selenium poisoning in northeast farming-grazing enterlocking district in spring-
