摘　　要：为紫阳县发展富硒产业及硒资源开发提供基础数据,对紫阳县双安镇、毛坝镇的土壤和岩石中的硒含量进行检测分析。结果表明:土壤样品中,双安镇硒含量在0.8038~16.3111 mg/kg,均超过0.4 mg/kg的富硒土壤标准,平均含量2.9107 mg/kg,接近极高硒土壤标准(3.00 mg/kg),极高硒土壤占17.8%;毛坝镇硒含量在0.1757~32.8394 mg/kg,平均4.8859 mg/kg,超过极高硒土壤标准,极高硒土壤占40.91%。岩石样品中,双安镇平均硒含量达18.5078 mg/kg,极高硒岩石占95%;毛坝镇岩石平均硒含量达4.7561 mg/kg,极高硒岩石占40%。The Se content of soil and rock in Shuang’an and Maoba Township is determined and analyzed to provide the basic data for development of Se-enriched industry and exploitation of Se-enriched resources in Ziyang County.Result:The Se content of soil samples from Shuang’an Township is 0.8038-16.3111 mg/kg,which exceeds the standard of Se-enriched soil(0.4 mg/kg).The average Se content of soil samples from Shuang’an Township is 2.9107 mg/kg,which is close to the standard of extremely high Se-enriched soil(3.00 mg/kg).The proportion of soil samples with the extremely high Se content level in total soil samples from Shuang’an Township is 17.8%.The Se content of soil samples from Maoba Township is 0.1757-32.8394 mg/kg.The average Se content is 4.8859 mg/kg,which exceeds the standard of extremely high Se-enriched soil and the proportion of soil samples with the extremely high Se content level in total soil samples from Maoba Township is 40.91%.The average Se content of rock samples from Shuang’an Township is 18.5078 mg/kg and the proportion of rock samples with the extremely high Se content level accounts for 95%.The average Se content of rock samples from Maoba Township is 4.7561 mg/kg and the proportion of rock samples with the extremely high Se content level accounts for 40%.
