Some wastewater sources, such as agricultural waste and runoff, and industrial sewage, can degrade water quality. This study summarises the sources and corresponding mechanisms that trigger eutrophication in lakes. Additionally, the trophic status index and water quality index (WQI) which are effective tools for evaluating the degree of eutrophication of lakes, have been discussed. This study also explores the main nutrients (nitrogen and phosphorus) driving transformations in the water body and sediment. Lake Erhai was used as a case study, and it was found to be in a mesotrophic state, with N and P co-limitation before 2006, and only P limitation since 2006. Finally, effective measures to maintain sustainable development in the watershed are proposed, along with a framework for an early warning system adopting the latest technologies (geographic information systems (GIS), remote sensing (RS)) for preventing eutrophication.
一些废水来源，如农业废物和径流以及工业污水，会降低水质。本研究总结了湖泊富营养化的来源和相应的触发机制。此外，还讨论了有效评估湖泊富营养化程度的营养状态指数和水质指数（WQI）。本研究还探讨了主要营养物质（氮和磷）在水体和沉积物中的转化。洱海被用作案例研究，结果表明洱海处于中营养状态，2006 年之前氮磷共同限制，2006 年之后只有磷限制。最后，提出了维护流域可持续发展的有效措施，并提出了采用最新技术（地理信息系统（GIS）、遥感（RS））的预警系统框架，以防止富营养化。
