摘要
水体富营养化是全球性环境问题，其引发的藻华、水质恶化及生态系统失衡对生态环境和人类健康构成严重威胁。为应对这一挑战，本研究聚焦于生物操纵技术在水体富营养化治理中的应用，旨在通过优化水生生态系统结构以实现水质改善与生态平衡恢复。研究采用实验室模拟与野外试验相结合的方法，系统分析了关键生物群落（如浮游动物、滤食性鱼类及沉水植物）之间的相互作用机制，并评估了不同生物操纵策略对氮磷去除效率及藻类控制效果的影响。结果表明，通过调控食物网结构和增强内部生态过程，生物操纵技术可显著降低水体中营养盐浓度，抑制藻类过度生长，并促进清水稳态的形成与维持。此外，研究创新性地提出了一种基于多功能生态位匹配的综合生物操纵模型，该模型能够根据不同水体特征定制化设计治理方案，从而提升技术的适应性和有效性。研究表明，生物操纵技术不仅具有良好的环境友好性，还能在一定程度上恢复受损生态系统的功能和服务能力，为水体富营养化治理提供了新思路和科学依据。

Abstract
Eutrophication of water bodies is a global environmental issue, and the resulting algal blooms, water quality deterioration, and ecosystem imbalance pose serious threats to ecological environments and human health. To address this challenge, this study focuses on the application of biomanipulation techniques in the management of water eutrophication, aiming to improve water quality and restore ecological balance by optimizing the structure of aquatic ecosystems. A combination of laboratory simulations and field experiments was employed to systematically analyze the interaction mechanisms among key biological communities, such as zooplankton, filter-feeding fish, and submerged plants, and to evaluate the effects of different biomanipulation strategies on the efficiency of nitrogen and phosphorus removal and algae control. The results indicate that by regulating food web structures and enhancing internal ecological processes, biomanipulation techniques can significantly reduce nutrient concentrations in water bodies, suppress excessive algal growth, and promote the formation and maintenance of clear-water states. Furthermore, this study innovatively proposes an integrated biomanipulation model based on multifunctional niche matching, which allows for customized design of management solutions according to the characteristics of different water bodies, thereby improving the adaptability and effectiveness of the technology. This research demonstrates that biomanipulation techniques not only exhibit good environmental friendliness but also partially restore the functions and service capacities of damaged ecosystems, providing new insights and scientific evidence for the management of water body eutrophication.
