摘　　要：从水文角度,提出了包括最小生态基流满足率、断流指数、环境适宜指数、含沙量指数及输沙平衡程度指数5大要素构成的指标体系及评价标准,采用模糊综合评价模型,得出辽河中下游河段水文生态完整性评价结果,为日后辽河中下游河段的保护、修复与管理提供了决策依据。To provide decision-making basis for the protection, restoration and management of middle and lower Li-aohe river, we put forward an index system and criteria for the hydroecological integrity assessment. The index sys-tem includes minimum expected fill rate of instream flow, zero flow index, environment suitability, sediment con- centration, and sediment transport equilibrium index. Fuzzy comprehensive assessment model was employed for the hydroecological integrity assessment. Results showed that the hydroecological integrity of Liaohe river is in an aver-age level.
