摘　　要：从水文水资源、物理结构、水质、生物和社会服务功能等5个准则层和14个指标层对2011年的嫩江下游尼尔基—三岔河口段河流健康状况进行评价。结果表明,受人类开发活动影响,嫩江下游河流健康评价指数赋分为59分,河流处于亚健康状态;农业开发、水利工程建设、过度捕捞等人类干扰是造成下游河流生境变化的主要因素。提出了水利工程生态调度、河岸带修复与管理、水质修复、栖息地修复、湿地生态系统恢复等河流健康管理措施。Based on the criterion layer consisting of hydrology and water resources,physical structure,water quality,biology and social service function,etc. and the index layer consisting of 14 indexes,the river health of Nierji-Sancha River Estuary in the downstream of Nenjiang River in the year of 2011 was assessed. The results show that,affected by human activities,the score of Nenjiang river health assessment index is 59 and the river is in the sub-healthy status. Agricultural development, water conservancy construction, overfishing and other human disturbances are the main factors contributing to eco-environmental changes of river downstream. Countermeasures of river health management including ecological operation of water conservancy project,riparian restoration and management,water quality restoration,habitat restoration,wetland ecosystem restoration were put forward.
