五莲县小(2)型水库健康评价及管理

Health Assessment and Management of Small-sized II Reservoirs in Wulian

摘要:

五莲县小(2)型水库在当地水利体系中作用关键,但在管理运行中出现工程设施老化、调度管理缺乏科学性、周边生态环境破坏等问题。文章以《河湖健康评价指南(试行)》为基准构建指标模型,对五莲县131座小(2)型水库展开调查评估。结果显示:5.34%的水库处于“非常健康”状态,79.39%为“健康”,11.45%为“亚健康”,2.29%为“不健康”,1.53%为“劣态”。针对这些问题,提出从水域岸线管理保护、水资源管理保护、水污染防治、水环境与水生态修复、水旱灾害防御和日常管理能力提升等方面提出建议,助力水生态环境改善和乡村振兴。

Abstract:

Small-sized II reservoirs in Wulian County play a critical role in the local water system. However, problems such as aging engineering facilities, unscientific operation and dispatch management, and damage to the surrounding ecological environment have emerged during their management and operation. Based on the Guidelines for Health Assessment of Rivers and Lakes (Trial), this paper establishes an indicator model and conducts an investigation and assessment to 131 small-sized II reservoirs in Wulian County. The results show that 5.34% of the reservoirs are in a "very healthy" state, 79.39% "healthy", 11.45% "sub-healthy", 2.29% "unhealthy", and 1.53% "poor". In response to these problems, suggestions are put forward from the aspects of water and shoreline management and protection, water resources management and protection, water pollution prevention, water environment and water ecological restoration, flood and drought disaster prevention, and improvement of daily management capacity, so as to promote the improvement of water ecological environment and rural revitalization.
