摘　　要：富营养化是导致湖泊生态系统退化的主要因素。生态恢复必须将生态理论与社会、经济条件相结合,确定合适的目标。实践证明,湖泊生态系统恢复可以显著改善水质。控制或削减外源营养盐负荷是富营养化湖泊生态恢复的前提,但成功生态恢复的负荷或湖水营养盐浓度条件因湖泊形态、地理位置和系统结构的不同而不同,我国湖泊的生态恢复需要在恢复条件、机理与技术多方面开展研究。Eutrophication is the main factor for the degradation of lake ecosystem. Ecological recovery must combine the theory of ecology with the condition of society and economy, then ensuring appropriately target. It is demonstrated that the recovery of lake ecosystem may greatly improve water quality. The precondition of lake ecosystem recovery is to control or reduce load of outsouree nutrient salt. However, considerations shall be given to the varies conditions of lake, its geological location and system structures which determined the load or nutrient salt of lakes for the success of ecological recovery. Studies shall be made on multi-respects of recovery conditions, mechanism and technologies.
