长江流域水资源调控与水库群调度

长江流域不仅存在着干旱缺水问题,也普遍存在水质性缺水和水生态功能退化问题,迫切需要加强严格的水资源管理和水利工程系统的优化调控。随着三峡、南水北调中东线等重大水利工程建成运行,为流域水资源调度提供了必要的工程手段,而三条红线等水资源管理措施的推进,使长江流域水资源管理和水利工程调控水平显著提高。本文首先回顾随着经济社会发展长江流域水资源供需关系变化,水库建设和水资源调控发展历程,然后通过引江济太工程调度、汉江的丹江口水库和长江三峡等控制性水库调度实践,讨论长江水资源综合调控技术进展及存在的问题,最后对于未来水资源综合调控中的科学、技术和管理方面需要开展的研究进行展望。

Regulation of water resources and operation of reservoir group in the Yangtze River basin

The Yangtze River basin is facing severe issues such as shortage of water resources, degradation of water quality and water ecology. It is urgent to strengthen the strict water resources management and the optimal regulation of water conservancy system. The Large-scale water conservancy project, such as the Three Gorges, the mid-route and east-route of South-to-North Water Transfer Projects, have provided es-sential engineering measures for water resources allocation. Furthermore, the Three Red Lines of Water Re-sources Management, and other measures have improved managerial level of water resources and regulatory level of hydraulic engineering in the Yangtze River Basin. Firstly, this study reviewed the change of water resources supply and demand relationship in the context of socio-economic development, the progress of res-ervoir construction, water resources regulation. Secondly, the research progress and problems in the synthet-ic regulation technique of water resources of the Yangtze River basin have been introduced based on the water diversion project from Yangtze River to Tai Lake basin and the operation of controlled reservoirs such as Danjiangkou Reservoir on the Han River and Three Gores on the Yangtze. Finally, the scientific, technical and administrative research which should be taken in the further comprehensive water resources regulation has been discussed.
