东江源寻乌水河流健康指标评价

Assessment of River Health Index of Xunwu River in Dongjiang Source Area

河流健康评价是流域系统规划和管理的主要依据。根据河流健康评价相关理论,构建了由河流完整性与稳定性、水文水资源情势、水环境指标、水生生物及栖息地和社会环境及服务能力5个准则层和28个指标集组成的河流健康评价体系。采用层次分析法确定了河流健康体系中指标的权重,运用综合评价法计算得出寻乌水河流健康综合指数。评价结果表明寻乌水河流健康状况为优。最后指出了寻乌水河流健康治理薄弱环节,以促进流域健康向良性方向发展。

The river health assessment is the primarily basis of basin planning and management. A river health assessment system were developed and it was composed by 5 criterion layers（ such as the river integritystability,the hydrologywater resources situation,the water environment index,the aquatic organismshabitats and the social environmentservice ability） and 28 specific indexes. The analytic hierarchy process（ AHP） was used to calculate the index weight. The comprehensive evaluation method was used to calculate the river health index. The results showed that the health grade of Xunwu river was excellent. This paper also pointed out its weaknesses,hoping to promote the healthy development.
