水体富营养化是指水体内氮磷营养元素富集，使水质恶化，藻类异常增殖的过程．生态浮床技术，通过植物根系吸收、吸附、截留及根系微生物分解水体中的氮、磷等营养物质，再通过收割植物将其搬离水体，从而达到净化水质的目的．国内外研究较多的水生植物有挺水植物、漂浮植物、浮叶植物和沉水植物等．为了克服传统生态浮床净污主体的单一性，在其基础上衍出了水生动植物组合式生态浮床．

Water eutrophication is a process that the elements nitrogen （N） and phosphorus （P） in water are enriched to get algae multiply abnormally, causing the deterioration of water quality. Ecological floating bed technology is to purify water through plant roots＇ absorbing, adsorbing and holding back the nutrients N and P, through decomposing the nutrients N and P by rhizosphere microorganisms, and then the plants are removed. The domestic and foreign researches on aquatic plants are mainly about emerged plants, floating plants, submersed plants, submerged plants, etc. Aquatic animal and aquatic plant floating bed is invented to avoid the singleness of traditional technology.
