湖泊富营养化的治理实践从控制营养盐、直接灭藻到生物调控和生态修复，走过了漫长而艰难的道路。尽管许多国家投入巨资，但收效甚微。湖泊富营养化仍然是一个严重的全球水环境问题。回顾和分析这方面的研究和实践中的经验和教训，无疑对于采取更可行的技术来有效控制湖泊富营养化是非常有益的。综合考察国内外湖泊富营养化治理研究成果，富营养化是一个典型的生态问题。生态问题只能通过生态方式解决。由于富营养化无法在整个湖泊范围内得到快速控制，因此，在一些受富营养化影响人类生产和生活的重要区域，如何集中技术和财力控制富营养化是关键。逐渐地，退化的生态系统可能会得到补救；自净能力增强，水质改善。最终恢复健康的湖泊生态系统。
The practice of controlling lake eutrophication has come a long and difficult way from controlling nutrient, direct killing algae to biomanipulation and ecological restoration. Although many countries have put a huge amount of money into it, little effect has been produced yet. Lake eutrophication is still a serious global hydro environmental problem. To review and analyze experience and lessons drawn from researches and practices in this regard will undoubtedly be very beneficial to the adoption of more feasible techniques in effectively controlling lake eutrophication. After a comprehensive survey into worldwide research results in controlling lake eutrophication, it is obvious that eutrophication is a typical ecological problem. Ecological problems can only be solved through ecological ways. Since eutrophication can not be quickly controlled in whole lake scale, it's the key how to centralize technical and financial resources for controlling the eutrophication in some important areas where human production and life are greatly affected by eutrophication. Gradually, the degraded ecosystem might be remedied; self purifying capability enhanced and water quality improved. A healthy lake ecosystem will be restored finally.
