西辽河流域生态调度实践与洪水资源化利用效应研究
Effect study on ecological regulation practices and flood resource utilization in the Xiliao River basin
摘要
Abstract
As an important ecological corridor in northern China,the Xiliao River has long faced problems of water depletion and ecological degradation.This article was based on the practice of unified river basin scheduling since 2020.It proposed a comprehensive management model of"flood control,flood utilization,and flood tailoring"coordination and explored the integration path of flood resource utilization and ecological recovery.According to the characteristics of floods in the basin,a refined scheduling system was constructed by relying on reservoirs such as Hongshan,Dongtaizi,Derisubaoleng,as well as river blocking hubs such as Sujiapu and Zongbanwopu.Classification measures were implemented:for major floods,flood diversion and storage will be the main focus,and the floods will be directed into the Xinkai River and nearby plain reservoirs such as Mengjiaduan and Molimiao to ensure flood control safety and supplement ecological water use;the goal of small and medium-sized floods is to achieve full line overflow,optimize ecological water replenishment flow,control the river floodplain,and maintain the stability of the ecological main channel.At the same time,relying on plain reservoirs,a composite groundwater recharge path of"river side infiltration+reservoir area infiltration"was constructed to replenish overexploited areas.The scheduling practice of 2024 and 2025 has verified the feasibility of the model.In 2024,the joint scheduling during the flood season extended the head of the main stream to 72.9 km below the Zongbanwopu hub.In 2025,under the unfavorable rainfall pattern of"abundant upstream and dry main stream"during the flood season,the first flood season after 27 years of interruption was achieved,and the entire line had water for 20 days.Research has shown that refined joint scheduling of reservoir groups can achieve spatiotemporal redistribution of flood resources.Simultaneously,controlling the discharge of about 60 m3/s can maintain the stability of the ecological main channel of the Xiliao River;the composite supply path provides support for regional ecological recovery.This model can provide a scalable solution for flood utilization and control systems for ecological restoration of rivers in northern water-scarce areas.关键词
