摘要
三峡库区是长江上游重要生态屏障,库区小型河流作为三峡库区水系的“毛细血管”,其健康状况对维持库区生态屏障功能至关重要。基于《重庆市河流健康评价指南(修订版)》,从岸线自然状况、水质优劣程度和公众满意度3个方面对重庆市云阳县8条三峡库区小型河流开展健康评价,并针对识别出的问题提出保护建议。结果显示,8条库区小型河流健康状态良好,河流健康评价综合得分为90.76~97.30,均属于一类河流(非常健康);部分河流在岸线自然状况和水质优劣程度方面存在短板。为保持和提升云阳县三峡库区小型河流的健康状态,建议加强岸线生态修复和农业面源污染治理,定期开展河流健康评价。研究成果可为制定相关政策和措施提供科学依据。
The Three Gorges Reservoir area serves as a critical ecological barrier in the upper Yangtze River basin.Functioning as hydrological capillaries,the health of its small tributaries is essential to sustaining regional ecosystem integrity.Following the“Chongqing River Health Assessment Guideline(Revised Edition)”,we evaluated the health of eight small tributaries within the Three Gorges Reservoir area in Yunyang County across three dimensions:riparian condition,water quality,and public satisfaction.Besides,we provide conservation recommendations for the identified issues.Results indicate that all eight rivers maintained excellent health condition,with composite scores ranging between 90.76 and 97.30,and are categorized as Class I(Excellent Health).Certain reaches exhibited weaknesses in riparian condition and water quality.To maintain and enhance the health of small rivers in the Three Gorges Reservoir area of Yunyang County,we recommend implementing riparian restoration and controlling diffuse agricultural pollution,supported by periodic health monitoring.This study offers a scientific reference for policy formulation and ecological measures.
