摘　　要：针对2015年和2016年2年枯水期鄱阳湖南矶山湿地土壤金属Cu污染变化,运用地累积指数法对其分析评价。结果表明:2次采样所得铜元素含量的变化范围为41.26～64.10 mg/kg。铜含量最高值2015年和2016年分别出现在苔草和荸荠群落、藜蒿和苔草群落,分别为48.58和64.10 mg/kg,而最低值均出现在湖底,分别为41.26和57.10 mg/kg。对2次样品进行污染评价,得出其地积累分级指数为2～3,属于中等-强度污染区域,且铜污染程度以19.55%～38.39%的速度在增加。因此应重视铜元素的污染,加大对污染的预防和管理。Based on the changes of Cu pollution in soil of Nanjishan wetland of Poyang Lake in 2015 and 2016, the Cu content of soil was measured by PerkinElmer A Analyst 200 atomic absorption spectrophotometer, and then analyzed and evaluated by the geoaccumulation index method. The results showed that the change range of Cu content after two samples was 41.26-64.10 mg/kg. In 2015 and 2016, the highest Cu content occurred in communities of Carex tristachya and Heleocharis dulcis , which were 48.58 mg/kg and 64.10 mg /kg, respectively, while the lowest were 41.26 mg/kg and 57.10 mg /kg, respectively. Based on the pollution assessment of two samples, it is concluded that the accumulation grading index is 2-3, belonging to the medium-intensity pollution area, and the copper pollution degree is increasing by 19.55%- 38.39%. Therefore, the pollution of copper should be emphasized and the prevention and management of pollution should be strengthened.
