摘　　要：水生态健康评价结果可指明水生态系统中的薄弱环节,为进一步提升水生态质量提供方向。通过分析大宁调蓄水库2017年水生态监测数据,对水库进行水生态健康评价,分析出影响水库水生态健康评价结果的主要扣分指标为大型底栖动物、水库更新周期、蓄水比及水面面积等。明确影响水库水生态健康的主要因素为大型底栖动物种类和数量、入库水量及水库水位,并针对水生态健康评价中发现的问题提出未来持续提升大宁调蓄水库水生态健康水平的措施和建议,为其他类似工程开展水生态质量提升工作提供思路和方法。The results of water ecological health assessment can point out the weak links in the aquatic ecosystem and provide direction for further improving water ecological quality.Based on the analysis of the water ecological monitoring data of Daning Reservoir in 2017,this paper evaluated the water ecological health of the reservoir,and pointed out that the main deduction indicators affecting the water ecological health evaluation results of the reservoir were macrobenthos,reservoir renewal cycle,water storage ratio and water surface area.The research clarified that the main factors affecting the water ecological health of the reservoir were the species and quantity of macrobenthos,the reservoir inflow and the reservoir water level.According to the problems found in the water ecological health assessment,the measures and suggestions for continuously improving the water ecological health level of Daning Reservoir in the future were put forward.It would provide ideas and methods for other similar projects to carry out water ecological quality improvement.
