摘要
永定河是贯穿京津冀生态功能区的天然走廊,也是京津冀地区重要水源涵养区和生态屏障。然而现实中永定河北京段水资源严重匮乏、河流生态廊道功能基本丧失,从分析永定河历史水文节律、科学认知生物节律和水文过程互馈响应的基础上,围绕有限水资源条件下河流廊道生态修复的基本问题,以永定河脉冲生态补水试验为抓手,开展了近自然水文节律恢复、受损严重河流形态的重塑和河流廊道生物栖息环境优化研究,提出了长期干涸沙化的季节性、游荡型河流生态修复关键技术,支撑永定河全线恢复通水及平原南段生态廊道修复。
Yongding River is a natural corridor that runs through the Beijing-Tianjin-Hebei ecological function zone,and is also an important water conservation area and ecological barrier in the Beijing-Tianjin-Hebei region.However,in reality,the Beijing section of the Yongding River is seriously lacking in water resources and the function of the river’s ecological corridors is basically lost.Based on the analysis of the historical hydrological rhythms of the Yongding River,scientific cognition of biological rhythms,and the mutual feedback of hydrological processes,this paper focused on the basic problems of river corridor ecological restoration under the limited water resources.The study started with the Yongding River pulse ecological water supplement experiment,carried out the research including the restoration of near-natural hydrological rhythm,the reconstruction of severely damaged river morphology,and the optimization of the biological habitat of the river corridor.The key technologies for ecological restoration of seasonal and wandering rivers,which were long-term drying and desertification will support the restoration of water supply across the Yongding River and the restoration of ecological corridors in the southern section of the plain.
