| 摘要: |
| 2001-2011年(不含2004年)10年间对江苏省五大湖泊(太湖、滆湖、洪泽湖、高宝邵伯湖和骆马湖)的水体重金属浓度进行长期定点监测,按系统分组资料进行方差分析,以比较各重金属浓度在湖泊间的差异显著性,并在此基础上应用多指标综合评价法(TOPSIS法)对5个湖泊水体重金属进行综合比较.结果表明:除铜浓度外,5个湖泊间铅、镉、汞和砷4个指标浓度均存在极显著差异;5种重金属浓度湖泊内站位间均差异不显著;铅、镉和汞浓度站位内年份间差异显著或极显著.TOPSIS分析结果表明,总体而言高宝邵伯湖水体重金属污染程度最小,骆马湖水体重金属污染程度最大,洪泽湖、太湖和滆湖水体重金属污染综合评价优劣相当. |

| Abstract: |
| The long-term localization monitors on heavy metals during the past 10 years from 2001 to 2011(except 2004) were carried out in water of the five great lakes, including Lakes Taihu, Gehu, Hongze, Gaobaoshaobo and Luoma in Jiangsu Province. Nested data variance analysis was performed in order to compare the difference of heavy metals among the five above-mentioned lakes, and the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) method was employed to give a comprehensive assessment of heavy metals. The results indicated that concentrations of Pb, Cd, Hg and As were all very significantly different compared within the lakes except Cu. In addition, the concentrations of the five heavy metals at each monitor station were not significant. Concentrations of Pb, Cd and Hg were significant or very significantly different among years for each station. The TOPSIS results showed that the pollution of heavy metals in water of Lake Gaobaoshaobo was the smallest but was the greatest in Lake Luoma. For the remaining three lakes, the pollutions of heavy metals were almost at the same level. |
