江汉平原沙洋地区表层土壤中硒的分布特征及富硒原因分析
|
摘要
以江汉平原沙洋地区为研究区,采集154个表层土壤样品,综合表层土壤样品的主微量元素含量、pH值和有机碳(TOC)等地球化学指标,系统地探讨了沙洋地区表层土壤中硒(Se)含量的分布特征、硒来源以及土壤理化性质对硒分布的影响。结果表明:沙洋地区表层土壤中Se含量介于0.07～1.48mg/kg之间,90%以上表层土壤样点呈足硒状态;富硒土壤主要分布于西荆河东岸的李市镇和官垱镇,面积约为80km2;沙洋富硒区土壤中主微量元素含量及主要参数与汉江沉积物相近,而与长江沉积物和沙洋过渡区土壤有一定的差异,指示其物源为汉江沉积物;表层土壤中硒的含量与土壤酸碱度(pH值)、TOC含量以及铁铝氧化物(Fe2O3、Al2O3)含量具有良好的相关关系,说明沙洋地区表层土壤中硒分布不仅受控于成土母质,还受土壤理化性质的影响。
Taking Shayang area of Jianghan Plain as the research area,this paper collects 154 surface soil samples,and systematically discusses the distribution of Se in surface soil,the source of Se enrichment and the effects of soil physicochemical properties on Se distribution in soil by synthesizing the main elements,trace elements,pH value and TOC of surface soil samples.The results show that the total Se content in surface soil from Shayang area range from 0.07 to 1.48 mg/kg,with an average of 0.33 mg/kg,more than90% of the topsoil are Se-sufficient,and Se-rich soil is mainly distributed in GuanDang town and LiShi town,about 80 km2.The concentrations and main indexes of Se-rich soil are different from that of the sediment of the Yangtze River and the slope wash of transition region,but similar to that of the Han River,which indicates that the main provenance of Se-rich soil is Han River sediments.Soil pH,organic matter,iron and aluminum have significant correlation with Se contents in surface soil,which shows that the contents of Se in surface soil is controlled not only by parent material,but also the physicochemical.
