国家水网视角下的洪水资源化利用探讨OA

Based on a profound understanding of the long-term history of water management and the practices in the new era,China has proposed three flood governance models:flood control,flood utilization,and flood shaping.Against the backdrop of intensified weather system evolution due to global climate change and the increasing frequency of extreme precipitation events in China,enhancing the resource utilization of floods is a crucial aspect of flood management,holding significant importance for alleviating the imbalance between water supply and demand in the country.From the macro perspective of the basic water situation in China and national water network construction,it is necessary and feasible to carry out large-scale spatio-temporal flood resource utilization.To promote the utilization of flood resources based on the national water network,it is first necessary to quantitatively assess flood resource potential for utilization on large spatio-temporal scales,clarifying the baseline.Secondly,it is essential to construct a national water network simulator based on the natural-artificial dualistic water cycle,so as to achieve"forecasting,early-warning,rehearsal,and contingency planning"for flood resource utilization.Finally,it is important to consider multiple objectives,such as flood control and water supply,and fully leverage the comprehensive function of the national water network to balance water resources with population and economic layout and support high-quality economic and social development.
