摘　　要：利用2022年南昌市主要湖泊监测数据,采用综合营养指数法分析南昌市主要湖泊富营养状态的总体状况及其随季节变化规律,进一步计算2018—2022年南昌市典型湖泊富营养状态秩相关趋势及各污染指标变化比例。结果表明,2018—2022年南昌市主要湖泊富营养状态处于中富营养与轻富营养之间,总体呈下降趋势,其中总磷的浓度下降明显。少数湖泊污染指标出现反弹,污染主要源于城市生活垃圾、生活污水、工业废水等点源污染和农林业化肥、水体养殖污染、湖内底泥等面源污染。在此基础上提出将控制污染源和生态修复结合,加强监管,提高人们环境意识等防治对策。Using the monitoring data of several major lakes in Nanchang in 2022,the comprehensive nutrient index method is used to analyze the overall status of eutrophic status of major lakes in Nanchang and its changing law with season,it calculates the rank-related trend of eutrophic status of typical lakes in Nanchang and the proportion of change of each pollution indicator in 2018—2022.The results show that in recent years the eutrophic status of the major lakes in Nanchang has been in the middle of the range between medium eutrophication and light eutrophication.The overall trend is decreasing,in which the content of total phosphorus decreases significantly,but there are still lakes with minority pollution indicators rebound,the reason is mainly from urban garbage,sewage,industrial wastewater and other point source pollution and agriculture and forestry fertilizers,aquaculture pollution,lake sediment and other surface source pollution.Control strategies and suggestions that combine pollution control with ecological restoration,strengthen supervision,and enhance people's environmental awareness were proposed.
