摘要:
为了解大庆龙凤湿地土壤理化性质对硒的含量、形态与分布的影响，对大庆龙凤湿地保护区4个样区20个样点4个不同层次土样中硒的含量、形态、分布以及部分理化性质进行了研究。结果表明：大庆龙凤湿地土壤全硒含量为121～150 μg/kg，由于硒淋溶流失的影响，随土壤深度的增加，全硒含量无明显变化；有效硒总量为22～28 μg/kg，包括水溶态硒、交换态硒与富啡酸态硒三种形态。影响土壤硒的主要因素包括土壤有机质、土壤黏粒含量及pH值，其中土壤有机质、黏粒含量与硒含量之间存在正相关关系，土壤pH值与硒含量存在极显著的负相关关系。
Abstract:
In order to understand the effect soil properties on the contents, species and distribution of selenium (Se) in soil in Longfeng wetland of Daqing, the contents of Se were measured by a method of successive extraction, physical and chemical properties of soil affecting the deposition of Se were determined. The results showed that Se contents in the profile distribution present no obvious pattern by dissolving, amplitude between the 121～150 μg/kg. The contents of available Se including water soluble Se, exchangeable Se, and acid soluble Se, were 22～28 μg/kg. There were a multiplicity factors that affect the distribution of Se, including organic matter, clay fraction and soil pH. The contents of Se had a positive correlation with organic matter, clay fraction, and had a negative correlation with soil pH.
