中文摘要:
      在贵州省兴仁市耕地质量地球化学调查评价基础上,研究了兴仁市耕地土壤中硒的地球化学特征、来源以及影响因素。结果表明,兴仁市耕地土壤硒的算术平均值为 042 mg/kg,背景值为 034 mg/kg,富硒耕地面积为 3145 万亩,占全县耕地面积的3402%;兴仁市耕地土壤中Se主要来源于成土母质,其中二叠系的煤系地层是高硒的主要来源;研究区土壤硒含量同时受土壤类型、土地利用方式、有机质含量、pH值影响。
英文摘要:
      Based on the survey and evaluation of cultivated land quality geochemistry in Xingren City, Guizhou Province, the overall distribution characteristics, sources and influencing factors of selenium in cultivated land soil were studied. The results show that the arithmetic average of selenium in cultivated soil in Xingren City is 0.42 mg / kg, the background value is 0.34 mg / kg, the selenium-rich cultivated land area is 314 500 mu, accounting for 34.02% of the county’s cultivated land area; the cultivated land soil in Xingren City Middle Se is mainly derived from the parent material of the soil, of which the Permian coal stratum is the main source of high selenium; the soil selenium content in the study area is also affected by soil type, land use,organic matter content, and pH.value.
