中文摘要:
      在充分考虑国内外河流健康研究基础上,建立了15个评价指标构成的广水河河流健康评价指标体系,确定了河流健康状况的评价标准,将其健康水平划分为“很健康、健康、亚健康、不健康、病态”五个等级,运用AHP-综合指数法对广水河健康状况进行评价. 结果表明:广水河健康综合指数为3.1963,健康状况总体处于亚健康水平. 广水河的河流健康状况主要存在以下问题:水量和水资源承载力不足;部分河岸坍塌;水体污染,部分河段呈轻度富营养化状态;水土流失加剧而导致河床淤积;水生生物减少. 根据评价结果及问题分析,提出了相应的保护及修复措施,为广水河流域的保护提供了可借鉴的决策依据,也对同类型的河流保护具有一定的指导意义.
英文摘要:
      Based on the definition of river health according to the references, present work has established an evaluation index system including 15 indexes for health assessment of Guangshui River. The evaluation criteria of river health status were determined and the river health level of Guangshui River was divided into five grades: very healthy, healthy, sub-healthy, unhealthy and morbid. AHP-composite index method was used to evaluate the health condition of Guangshui River. The results showed that the composite health index of Guangshui River was 3.1963 and indicated that the overall health status was at sub-health level. The problem of the Guangshui River health was as follows: the insufficiency of water quantity and the bearing capacity of water resources; the collapse of partial banks; water pollution and mild eutrophication of partial reaches; the aggravation of water and soil erosion leading to the deposition of river bed; the reduction of biodiversity aquatic organisms. Based on the evaluation result and reason analysis, the protection and restoration measurements were proposed and provided decision bases for the Guangshui River. The results also provide the guideline significance for the protection of the same type of rivers.
