| 摘 要： | 对巢湖2000—2008年的监测数据运用SPSS做统计分析,得出叶绿素a与总氮、总磷和透明度的相关系数。通过得出的权重结果,分析出与26个湖泊的差异性,构建了改进的综合营养状态指数(TLI)评价方法,并提出评价的4个步骤。以巢湖为例,运用该方法对湖泊的营养状态进行评价,且对巢湖的富营养化程度做了年际和年内变化的综合评价,评价结果显示各营养物指标的相关关系在近30年有了较大变化,巢湖的富营养化现象已日益严重,已从轻度富营养化状态转变为中度富营养化状态。 |
| 关 键 词： | 巢湖 评价方法 富营养化 TLI指数法 |

| Abstract: | Monitoring data from 2000 to 2008 of Chaohu Lake were analyzed using SPSS (13.0) software package. Correlation coefficients between chlorophyll-a and total nitrogen, total phosphorus as well as transparency were obtained from the analysis. The differences between Chaohu Lake and other 26 lakes were then analyzed through the weights. An improved comprehensive nutrition state index method evaluation method was developed and four-step evaluation approach was proposed. In the case of Chaohu Lake, the lakes nutritional status was evaluated, and the inter-annual and annual variation eutrophication levels were comprehensive evaluated. The results showed that the interrelation of each nutrient indicator has changed significantly in recent 30 years. The eutrophication problem in Chaohu Lake has become increasingly serious. The eutrophication level of Chaohu Lake has changed from mild eutrophic into a moderate eutrophic state. |
| Keywords: | Chaohu Lake evaluation method eutrophication comprehensive nutrition state index method |
