介绍了我国13个城市及其周边地区汞污染土壤中汞的形态特征研究成果。通过对汞污染土壤化学分析、形态分析、热释汞研究、重矿物研究发现，我国城市汞污染土壤中HgS是Hg的主要存在形态，13城市汞污染土壤重矿物研究中辰砂的大量出现及其含量与分布特征也进一步佐证了这一结论。汞污染土壤中汞污染程度越高， HgS含量越高，辰砂出现几率越大，且含量越高。该成果对我国汞污染调查研究和汞污染土壤生态地球化学环境评价具有重要的理论价值和实际意义。

The modes of occurrence of Hg in Hg polluted soil of 13 cities, such as Beijing, Shenyang, Changchun, Nanjing, Guang-zhou and Lanzhou, are described. Hg pollution was found in different cities through Hg occurrence analysis and heat-released Hg analy- sis. Mineralogical method has proved the above conclusion. HgS is the main mode of occurrence of Hg in polluted soil. Cinnabar which is the crystal mineral of HgS exists in soil. The appearance rate of cinnabar in soil increases with the Hg content in polluted soil. The re-sults have significant theoretical and practical value for eco-geochemical evaluation which has been carried out extensively in China.
