A review on the application of eco??technology for restoring eutrop hicated lakes and reservoirs in China

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.
