河北省滹沱河水文完整性评价及变化趋势分析OA
Assessment of Hydrologic Integrity and Analysis of Trends in the Hutuo River,Hebei Province
为深入了解滹沱河水文完整健康情况,建立包括生态流量(水量)满足程度、流量过程变异程度和河流断流程度3项关键指标的综合评价体系.采用百分制加权赋分法,得出滹沱河水文完整性综合评分.研究表明,滹沱河水文完整性 2017 年综合评分为 61.18 分,2021 年综合评分为 84.4 分,呈上升趋势.研究有助于维持和提升滹沱河水文完整性现状.
To gain an in-depth understanding of the hydrologic integrity and health of the hutuo river,a comprehensive assessment system was established.This system incorporates three key indicators:the degree of satisfaction of ecological flow(water quantity),the degree of deviation of the flow regime,and the degree of river flow interruption.Using a percentage-based weighted scoring method,a comprehensive score for the hydrologic integrity of the hutuo river was derived.The study indicates that the comprehensive score for the Hutuo river's hydrologic integrity was 61.18 in 2017 and increased to 84.4 in 2021,demonstrating an upward trend.This research contributes to the maintenance and enhancement of the current state of hydrologic integrity in the Hutuo river.
