黄河健康评价与修复基本框架

河流健康评价与修复是当前河流管理领域的研究热点。黄河生态退化日趋严重,研究其健康评价与修复,具有较强的理论与现实意义。在探讨黄河健康内涵的基础上,构建了黄河健康评价框架,包括干流与支流健康,河源、上游、中游、下游与河口段健康,流域社会经济与自然生态系统健康;建立了包括水质、水量、水生生物、物理结构与河岸带等5个要素的黄河健康表征指标体系;还提出宏观、中观与微观3个层次上的黄河河流修复内容,识别出黄河修复的优先行动领域。

Basic Frameworks of Health Assessment and Restoration of Yellow River

Much attention has been paid to river health assessment and restoration.Ecological degradation of Yellow river has been serious,thus the study on its health assessment and restoration is of great significance in theory and practice.Based on the analysis of Yellow river health connotation, the health assessment system of Yellow river,including the mainstream and branch health,river headstream,upstream,middle stream,downstream and river mouth health,watershed socio-economy and natural system health,are framed,and the performance indicator system of Yellow river health,consisting of five components as water quality,water quantity,aquatic life,physical form and riparian zone,is established.Moreover,the restoration activities of macro,middle and micro level of Yellow river are put forward,and the priority areas of restoration are identified.
