河湖水系连通的理论探讨

在全球气候变化和水资源形势日趋严峻的背景下,为了从根本上提高水资源统筹配置能力、改善河湖健康状况和增强抵御水旱灾害能力,河湖水系连通作为国家新时期的一个治水方略被提出。当前关于河湖水系连通的理论基础研究要落后于实践,尚在探索之中。论文尝试从河、湖与水系等水循环基本概念入手,探讨水系的结构、特征和连通性,揭示水系连通的水循环物理机制,并进一步分析河湖水系连通的战略思想,探明其中涉及的几个关键水循环基础问题,包括水量平衡、能量平衡、水资源可再生性、水循环尺度等问题,为河湖水系连通战略的实施和理论体系的建立奠定基础。

Discussion on Water Cycle Mechanism of Interconnected River System Network

Climate change and human activities affected water supply and water management,and brought a lot of water issues,such as drought,flood,water shortage,deterioration of water environment,etc.In order to fundamentally increase water resources allocation ability,improve ecological environment quality,and enhance the capacity to withstand flood and drought disasters,in China,a new national strategic plan on the constructing river system network was put forward.We have called this plan as IRSN(Interconnected Rive...
