中文摘要：
Hg污染已成为全球性的环境问题，尤其是Hg对土壤的污染，因其具有隐蔽性、不可逆性和长期性的特点，对陆生生态系统构成潜在的巨大威胁，因此查明土壤中Hg的来源非常重要。运用生态地球化学填图的指导思想，对湖南洞庭湖地区土壤剖面分析和成土过程研究后发现，表层土壤中Hg含量的高低与成土母质中Hg的含量有很好的对应性，成土过程对土壤中Hg的含量也有显著的影响。
英文摘要：
Mercury poUudon has been generally recognized as a global environmental problem. It is particularly the case with mercury pollution of soils because it is well concealed, irreversible and long-continued, being a great potential threat to the terrestrial ecosys- tem. Therefore it is very important to make clear the source of Hg in soils. Based on an analysis of vertical soil profiles and soil-form- ing processes in the Dongting Lake area, Hunan, the authors find that there is a good correspondence between the Hg content in topsoils and that in soil-forming parent materials. The soil-forming processes also have significant influence on the Hg content in soils.
