摘 要
水体富营养化是全球范围内广泛关注的环境问题，其对生态系统平衡及人类健康构成严重威胁。本研究旨在深入探讨水体富营养化的成因及其防治对策，通过综合分析自然因素与人为活动的交互作用，揭示关键驱动机制，并提出针对性解决方案。研究采用多学科交叉方法，结合水质监测数据、遥感技术及数值模拟手段，对典型富营养化水域进行长期动态观测与评估。结果表明，氮磷等营养物质的过量输入是导致水体富营养化的直接原因，而气候变化、土地利用变化及不合理的农业管理则进一步加剧了这一过程。此外，研究发现微生物群落结构与功能在富营养化进程中扮演重要角色，为生态修复提供了新思路。

Abstract
Water eutrophication is a widespread environmental concern around the world, which poses a serious threat to ecosystem balance and human health. This study aims to explore the causes of water eutrophication and its prevention countermeasures, comprehensively analyze the interaction between natural factors and human activities, reveal the key driving mechanism, and propose targeted solutions. The study adopts a multidisciplinary method, combined with water quality monitoring data, remote sensing technology and numerical simulation means, to conduct long-term dynamic observation and evaluation of typical eutrophication waters. The results show that the excessive import of nutrients such as nitrogen and phosphorus is the direct cause of eutrophication in water bodies, and this process is further exacerbated by climate change, land use change and unreasonable agricultural management. In addition, the study found that the structure and function of microbial community play an important role in the process of eutrophication, which provided a new idea for ecological restoration.
