摘要
我国湖泊、水库的营养化非常严重,且呈发展之势。在众多的治理方法中,生态方法以其效果好,费用低等优点,越来越受到人们的重视,成为国内外富营养化湖泊治理与研究的热点。本文将富营养化湖泊治理的生态技术分为控制营养盐的技术和直接控制藻类的技术,并分析了各种技术的生态原理、技术应用条件、实例应用情况以及技术优点和缺点等。湖泊富营养化是一个典型的生态问题,应综合各项技术的优点,科学地运用各项技术,实施富营养化湖泊的治理。
With rapid development of economy and society, pollution in water environment is getting more and more serious in China. Many lakes and reservoirs are faced with water problems such as water quality deterioration, overwhelming eutrophication, shrinking of lake area, heavy sedimentation in reservoirs, and so on. The most seriously problem is the eutrophication of lakes and reservoirs. A few methods to restore the eutrophicated lakes and reservoirs have been developed, in which the ecotechnology has become a promising one because of its advantage of high efficiency and low cost. The eutrophication of lakes and reservoirs is a typical ecological problem and can be solved only by applying eco-technologies comprehensively. This paper presents several eco-technologies, which can be classified as nutrition control method and algae control method. An evaluation is made on their advantages and disadvantages. For restoring eutrophicated lakes and reservoirs, a comprehensive management should be considered by taking advantages of different methods.
