摘要
以庐山市如琴湖为研究对象,基于水质状态和生态响应的富营养化综合评价模型分区对其进行富营养化评估,分析水体营养状态时空分布特征及底泥氮磷的影响。结果表明:如琴湖水体自西向东呈现“5(劣)、4(差)和5(劣)”程度富营养化,氮磷浓度增加是近几年如琴湖水体富营养化的主要驱动因子。底泥中TN、TP含量为重度污染,有较高的释放风险。底泥与水体中TN、TP浓度相关性较弱且受水深的影响,更容易释放到上覆水体中。如琴湖作为庐山市重要景点之一,对如琴湖进行富营养化评价,旨在提高居民关注度并为后续治理提供技术支撑。
This study evaluated the eutrophication status of Ruxin Lake using a comprehensive model integrating water quality and ecological response.Results showed that the lake exhibited"Grade 5(poor),4(bad),and 5(poor)"eutrophication levels from west to east,indicating nitrogen and phosphorus as key drivers.Sediment TN and TP levels indicate severe pollution and high release risk.Weak correlations between sediment and water nutrient levels,influenced by water depth,suggest easier nutrient release.As a key scenic spot,this assessment aims to raise public awareness and support future restoration efforts.
