摘要
通过对河套地区土壤背景值与基准值的确定与研究发现,河套地区主要是以富CaO、MgO及As、F等为主的地区,其他绝大多数元素的含量要低于全国以及世界水平。河套地区表层和深层土壤中样品含量也有一定的差别。此外长期的人类活动也对土壤中元素的含量变化产生比较明显的影响。通过对土壤基准值与土壤背景值的研究分析,为该地区农业、环境及地方病等方面的研究提供基础、全面的资料。
A study on characteristics of reference and background The results show that contents of the most elements in soils in this values of soils in Hetao Area was carried out. area are lower than those in the other areas in both China and abroad expect CaO, MgO, As and F, which are the major components in Hetao area. The results also indicate that the element contents in surface soil and deep layer soil are different. It means that human activ- ities have obvious influence on the change of the element contents in the soils. The results from the study on characteristics of reference and background values of soils in this area will provide basic data and information for agriculture development, environment protection, endemic disease prevention and cure, etc. in Hetao area.
