摘 要
本研究针对水体富营养化问题,深入探讨了其成因,并对生态修复技术进行了系统研究。富营养化现象主要是由于水体中氮、磷等营养物质过量积累所致,这通常源于农业排放、生活污水和工业废水的不合理排放。本研究旨在通过科学分析,揭示富营养化的根源,并探索有效的生态修复方法。我们采用了多种技术手段,包括生物修复、生态工程和水质净化等,以减缓富营养化进程并恢复水体生态平衡。实验结果显示,通过合理引入具有净化功能的水生植物和微生物,能有效吸收并降解水体中的营养物质,显著改善水质。同时,我们设计的生态浮床和人工湿地等生态工程措施也取得了显著成效,进一步验证了生态修复技术的可行性和有效性。本研究的创新点在于综合运用了多种生态修复方法,并对比分析了它们的实际效果。主要贡献在于为水体富营养化的治理提供了科学依据和实践指导,推动了生态修复技术的发展,对环境保护和可持续发展具有重要意义。

Abstract
This study conducts an in-depth exploration of the causes of eutrophication, a prevalent issue in water bodies, and systematically investigates ecological restoration techniques. Eutrophication primarily occurs due to the excessive accumulation of nutrients such as nitrogen and phosphorus in water bodies, often resulting from unreasonable discharges from agricultural runoff, domestic sewage, and industrial wastewater. Through scientific analysis, this research aims to uncover the root causes of eutrophication and explore effective ecological restoration methods. Various technical approaches, including bioremediation, ecological engineering, and water purification, have been employed to mitigate the eutrophication process and restore the ecological balance of water bodies. Experimental results indicate that the rational introduction of aquatic plants and microorganisms with purifying functions can effectively absorb and degrade nutrients in the water, significantly improving water quality. Additionally, the ecological engineering measures designed in this study, such as ecological floating beds and constructed wetlands, have achieved remarkable results, further validating the feasibility and effectiveness of ecological restoration techniques. The innovation of this research lies in the integrated application of multiple ecological restoration methods and the comparative analysis of their practical effects. Its primary contribution is providing scientific evidence and practical guidance for the management of eutrophication, advancing the development of ecological restoration technology, and carrying significant importance for environmental protection and sustainable development.
