| 摘 要： | 以高原深水抚仙湖为研究对象，分析了全湖16个样点表层沉积物（0~5 cm）的酸可挥发性硫化物（AVS）和同步提取重金属（SEM）的分布特征，并利用∑SEM和AVS的物质的量浓度比对全湖重金属潜在生态风险进行了评估.结果表明：AVS在南北湖区分布存在明显差异，南部湖区分布均匀，平均含量仅为0.074±0.043 μmol/g，而北部湖区则由湖岸带向北湖心（N9）呈现出递增趋势，平均含量高达0.317±0.485 μmol/g.SEM在南北湖区分布较为集中，南部湖区主要集中在路居河口（S2），北部湖区主要分布在老凹地（N5）和东大河口（N4）.除牛摩河口（S5）、梁王河口（N3）和北湖心（N9）外，其余所有点位[∑SEM]/[AVS]>1，且南部湖区平均[∑SEM]/[AVS]值（3.51±1.91）显著高于北湖湖区（2.19±2.10）.因此抚仙湖全湖尤其是南部湖区重金属生态风险应引起高度重视.
