| 摘 要： | 对南洞庭湖10个洲垸地点的土壤进行了4种重金属Cd、Pb、Cu、Sb含量的测定与分析，并运用地积累指数法对每种重金属的污染状况进行初步评价，结果表明，重金属Cd的污染普遍较为严重；重金属Pb未达到明显的污染水平；重金属Cu的污染程度虽较轻，但需控制其发展；重金属Sb在某些地点污染较严重，其分布规律呈现较强的不均衡性。

| Abstract: | Contents of cadmium, lead, copper and antimony in Chau embankment soil of south Dongting Lake were quantitatively analyzed, and the state of pollution was evaluated by the geo-accumulation index, the results showed that cadmium pollution was generally serious, lead was below the pollution level, copper should be controlled although with less pollution, and antimony showed an obviously uneven distribution. |
