摘要

极端干旱天气是导致水资源短缺最重要、最直接的原因, 河湖水量调度失衡无法缓解水资源紧缺的供需矛盾。在极端干旱和人为活动因素双重胁迫下, 河湖湿地生态系统严重受损, 湿地退化明显加剧。2022年极端干旱给长江中下游及洞庭湖、鄱阳湖等湿地生态造成了巨大影响。为了探讨这一迫切需要解决的重大难题, 本文以洞庭湖和长江相关河系的依存关系为研究对象, 通过广泛的资料收集、现场调研和理论分析, 在研究极端干旱气候特征与流域水文响应关系的基础上, 聚焦江湖水量调度管理与湿地生态风险管控两大科学问题, 探讨气候变化和人类活动下河湖水文要素变异特性, 提出生态环境优先保护和发展战略, 构建流域湿地生境与水资源保护治理新格局, 实现以目标管理为导向, 倒逼水量调度, 创新调控手段和技术方法, 优化河湖水量调度管理模式, 增强水资源调蓄能力, 为水资源利用与湿地生态保育的协同发展提供重要的理论价值。

Abstract

Extreme dry weather is the most important and direct cause of water shortage. The imbalance of water regulation of rivers and lakes cannot alleviate the contradiction between supply and demand of water resources. Under the dual stress of extreme drought and human activities, the river lake wetland ecosystem was seriously damaged and the wetland degradation was significantly intensified. The extreme drought in 2022 has made a huge impact on the middle and lower reaches of the Yangtze River including the wetland ecology of the related lakes such as the Dongting Lake and the Poyang Lake. In order to find out solutions of solving such major problem, this paper, takeing the dependency relationship between the Dongting Lake and the related water systems of the Yangtze River as the research object, through extensive data collection, field survey and theoretical analysis based on the study of the relationship between extreme drought climate characteristics and watershed hydrological response, focuses on the two major scientific issues of water regulation management and wetland ecological risk management and control, and explores the variation characteristics of river and lake hydrological elements under climate change and human activities. Finally, the priority protection and development strategy of ecological environment is proposed and a new governance pattern for wetland habitat and water resource protection in river basin is constructed to realize the goal-oriented management, reverse water dispatch, innovate regulation means and technical methods, optimize the water regulation and management mode of rivers and lakes, and to enhance the water resource regulation and storage capacity. This paper will provide important theoretical value for the coordinated development of water resource utilization and wetland ecological conservation.
