水体富营养化成因分析及治理措施
摘 要
本研究主要围绕水体富营养化展开，分析了富营养化对水生生态系统产生的多方面影响，包括生态平衡和生物多样性的破坏、水质和透明度的降低，以及对水生生物和人体健康的威胁。在成因分析部分，本文深入探讨了氮磷营养物质大量排放、水土流失和农业施肥、畜牧业与渔业排泄物污染以及生活污水与污水灌溉排放等因素对水体富营养化的贡献。最后，针对水体富营养化问题，本文提出了一系列治理措施，包括减排农业废水和生活污水、清理湖底淤泥和引活水入湖、完善法律法规并依法治污以及加强环保意识并推广绿色农业。这些措施旨在减缓或消除水体富营养化现象，保护水生生态系统的健康与稳定。

Abstract
This study focuses on water eutrophication and analyzes the multifaceted effects of eutrophication on aquatic ecosystems, including the effects of ecological balance and biodiversity damage, reduced water quality and transparency, and threats to aquatic life and human health. In the genetic analysis section, this paper deeply discusses the contribution of large discharge of nitrogen and phosphorus nutrients, soil erosion, agricultural fertilization, animal husbandry and fishery excrement pollution, and domestic sewage and sewage irrigation discharge to water eutrophication. Finally, for the problem of water eutrophication, this paper proposes a series of treatment measures, including reducing agricultural wastewater and domestic sewage, cleaning up silt from the lake at the bottom of the lake and diverting fresh water into the lake, improving laws and regulations and controlling pollution according to law, strengthening the awareness of environmental protection and promoting green agriculture. These measures aim to mitigate or eliminate eutrophication in water bodies and protect the health and stability of aquatic ecosystems.
