水体藻类过渡繁殖引起水体缺氧,透明度下降,致使水生动物窒息死亡,破坏水体生态系统,影响水质,危害人体健康与安全.综述3藻华的危害性,通过物理法、化学法和生物法,概述原位控藻的主要技术,分析与探讨多项技术实践结果的优缺点,认为以清除过多内源营养盐为主,同时结合运用控藻技术,加强外源截污与面源有效控制等环境质量管理的综合措施,是长期控藻与改善水质的重要方向.

Algae bloom causes water hypoxia and reduces water transparency, resulting in the suffocation and death of aquatic animals, destroying water ecosystems, and endangering human life and health. The harm of algae bloom and the major techniques for in situ algae control by the methods involving physics, chemistry, and biology are summarized; the merit and demerit of each technique are analyzed based on the algae control practices discussed. It is suggested that by removing excessive endogenous nutrients complemented with the algae control technique, meanwhile strengthening the environment quality management by intercepting pollution; these comprehensive measures would become the important direction to accomplish the long-term control of algae and the restoration of water quality.
