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。

关键词: 辽河 , 评价指标 , 模糊综合评判 , 水文生态完整性

Abstract: To provide decision-making basis for the protection,restoration and management of middle and lower Liaohe river,we put forward an index system and criteria for the hydroecological integrity assessment. The index system includes minimum expected fill rate of instream flow,zero flow index,environment suitability,sediment concentration,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 average level.

Key words: Liaohe river , assessment index , fuzzy comprehensive assessment , hydroecological integrity
