摘　　要：介绍了经典的湖泊生态修复理论在国内外的应用及发展现状,并总结了在该理论指导下实施城市湖泊生态修复过程中,内源及外源性营养盐、光照、浮游植物、底泥、生物扰动等因子对水生植物群落恢复的影响,及其应对策略。针对外源性点源、面源污染多的问题,通过修建污水管网以及人工湿地等水利设施进行控制;内源性污染如底泥,则可采用原位以及异位等处理技术进行控制;对水质产生较大影响的浮游植物可采用物理、化学、生物-生态学方法进行调控;人类干扰、鱼类牧食及其他水生动物、浮游植物等综合作用共同影响水生植物生长、分布。因此,在利用水生植物修复湖泊水体时,必须综合考虑多方面生态因子对其所造成的影响。We introduce the application and development of classical theories of lake ecological restoration in China and abroad,and summarized factors which play important roles in the process of lake ecological restoration and the corresponding coping strategies. These factors include internal and external nutrient,illumination,phytoplankton,sediment,and biological disturbance. Exogenous point source pollution and non-point source pollution are generally controlled by building sewage networks and artificial wetlands; whereas endogenous pollutions,for example bottom sediment,are controlled via in-situ and off-site remediation techniques. Phytoplankton,which largely affects water quality,could be regulated and controlled by adopting physical,chemical,and bio-ecological methods. Together with human disturbance,fish and other aquatic animals as well as phytoplankton affect the growth and distribution of aquatic plants. Therefore,the effect of ecological factors must be considered in the restoration of lake water body by introducing aquatic plants.
