摘要

摘要: 我国珠三角滨海地区的城市河流多为雨源型河流，因季节性缺水与生态韧性薄弱而备受关注。为了保障这些河流的基本流量、提升水环境容量及改善水质，采用再生水和雨洪水进行生态补水显得尤为重要。为科学评估这一补水措施的效果，引入了可靠性-弹性-脆弱性（RRV）评价框架，并首次构建了基于韧性评价的城市河流水环境模型。以深圳龙岗河流域为研究对象，该模型综合分析了流域内水质净化厂提供的再生水、非供水水库蓄积的雨洪水等多种补水水源。结果显示，再生水与雨洪水的补给均能有效提升河流的弹性与可靠性，其中雨洪水的改善效果尤为突出。对于污染程度较低的河流，雨洪水的均匀补给能显著提升其韧性。值得一提的是，补水措施对化学需氧量和氨氮的韧性改善效果尤为显著，最高可达80%，明显优于对总磷的改善。该评估框架为水环境韧性评估提供了有力工具，也将为流域水资源管理与调配的优化工作提供重要参考。

Abstract: As China's economy soars and urbanization accelerates， the inadequate sewage treatment infrastructure has resulted in a deteriorating urban water environment， particularly evident in water pollution. The southern coastal hilly regions face seasonal water scarcity， making ecological replenishment of rivers crucial. This study targeted the Longgang River watershed in these regions， utilizing reclaimed water and reservoir water for ecological replenishment. By integrating a coupled hydrodynamic-water quality model with a reliability， resilience， and vulnerability （RRV） assessment framework， the study quantified the resilience enhancement from reclaimed water replenishment. The results revealed that after replenishment with reservoir water， river resilience improved consistently with reliability， with the latter demonstrating a more pronounced enhancement. Notably， uniform replenishment with non-potable reservoir water significantly boosted the resilience of less polluted rivers. Additionally， the resilience-enhancing effects of replenishment were more pronounced for chemical oxygen demand （COD） and ammonia nitrogen （NH₃-N）， compared to total phosphorus （TP）. This study provides insights into optimizing water resource management strategies for resilient urban water environments.
