| 摘 要： | 分析南京玄武湖1997年-2010年的水质变化，以及生态补水与玄武湖水质变化的关系。结果表明，玄武湖于1998年实施生态补水，随着生态补水的持续运行和生态补水量的不断增加，玄武湖水质得以显著改善，其水质类别由生态补水前的劣V类水体转为V类水体，并接近于Ⅳ类水体，富营养化程度由重度富营养化水平转为轻度富营养化水平。目前玄武湖主要营养物质来源于生态补水，相关性分析显示各湖区TN浓度与生态补水中TN浓度呈显著相关关系。

| Abstract: | Combining the changes of water quality in Lake Xuanwu from 1997 to 2010 and their relationship between the ecological water compensation and lake water, it is showed that the water quality of lake water has been improved significantly due to the continuous running of the ecological water compensation since 1998. After the ecological water compensation, annual water quality reached better level of category V according to the Envi- ronmental Quality Standards for Surface Water （GB 3838 -2002） and the whole lake also switched from hyper- eutrophic level to light-eutrophic level. The main nutrient pools of the lake were supplied by the ecological water compensation at present. Correlation analysis indicated that the concentration of TN from the ecological water compensation was positively correlated with those from different regions of Lake Xuanwu |
