| 摘 要： | 对南四湖不同湖区的20个表层底泥样品的重金属和营养元素浓度做了实验分析,并采用主成分分析等数理统计的方法对底泥重金属和营养元素进行了研究,揭示出南四湖不同湖区重金属和营养元素空间分布的特征.结果表明,整个南四湖的上级湖已经受到金属和营养元素的污染.其中南阳湖的汞和营养元素污染严重,铅、砷等次之;独山湖的营养元素污染最重;昭阳湖污染较轻. |
| 关 键 词： | 南四湖 底泥 重金属 营养元素 多元分析 |

| Abstract: | Heavy metal and nutrient concentrations of 20 surface sediment samples from different areas of Nansihu Lake were analyzed experimentally; and the sediment heavy metal and nutrient were studied with mathematical statistics technique such as principal component analysis(PCA) to reveal the characters of spatial distribution of heavy metal and nutrient in different lake areas. The results showed that all the first level lakes of Nansihu were already polluted by heavy metal and nutrient, in which Nanyanghu was polluted seriously by mercury and nutrient and next by lead and arsenic; Dushanhu was polluted most seriously by nutrient; and Zhaoyanghu was polluted rather lightly. |
| Keywords: | Nansihu Lake sediment heavy metal nutrient multivariate analysis |
