河湖健康评估能够判断和评价河流的健康状态，不仅有助于河流管理决策者确定河流管理活动，还能够为河流保护和恢复提供科学依据。本文在分析贵州省六硐河河流健康内涵及指标体系的基础上，构建了由河流物理特征、水文水资源特征、水质状况、水生生物、社会服务功能等5个准则层和15个指标集组成的河流健康评价体系。将层次分析法和综合评估方法相结合，计算得到六硐河健康评估得分。结果表明，六硐河健康评估总得分82.32分，划分的8个河段的河流完整性得分范围在82.91-89.34之间，整个六硐河流域总体处于健康水平，但仍然有部分河段部分指标处于不健康状态，应采取预见性措施达到有效控制河流生态系统破坏的发生或发展，显著降低生态系统朝着不可恢复状态发展的概率和生态修复投入。

Ｒiver health assessment can judge and evaluate whether a river is in a healthy state，which not only helps river management department to determine management activities，but also provides a scientific basis for river protection and restoration． Based on the analysis of the connotation and index system of Liudong Ｒiver＇s health in Guizhou Province，this paper constructs a river health evaluation system consisting of 5 criteria layers and 15 index sets，including river physical characteristics，hydrological and water resources characteristics， water quality status，aquatic organisms，and social service functions． The health assessment score of Liudong Ｒiver was calculated by combining analytic hierarchy process and comprehensive assessment method． Our results show that the total health assessment score of Liudong Ｒiver is 82．32，and the river integrity scores of the eight divided sections are ranged from 82．91 to 89．34． The whole Liudong Ｒiver basin is generally in a healthy state，but some indexes of some river sections are still in an unhealthy state． Predictable measures should be taken to effectively control the occurrence or development of river ecosystem damage and significantly reduce the probability of ecosystem development towards an unrecoverable state and ecological restoration investment．
