摘　　要：雄安新区建设为白洋淀生态环境提出了更高的要求,生态需水是白洋淀生态修复的核心问题,加强生态需水研究对涵养地下水源、维护流域水生态平衡、增强水资源调蓄能力具有至关重要的作用。本文在雄安新区建设的大背景下,基于防洪、城市景观建设及芦植生长等实际需求,结合最新测量的水位-淹没面积关系,开展白洋淀生态水位核算。同时,分别从淀区水资源蒸发入渗消耗的刚性需求,以及改善淀区水动力条件和水生态环境质量的弹性需求两个方面,提出淀区生态需水量。从维持河道生态基流的角度,对上游八条入淀河流和新区范围内的大清河、赵王新河的最小生态需水量进行核算,作为河流生态逐步恢复的一个基本目标。在此基础上,针对性提出淀区补水方案,以及入淀河流需水保障措施,力求恢复白洋淀流域生态安全、提高雄安新区生态环境承载能力。The construction of Xiong'an New Area puts forward higher requirements for the surrounding environment. Ecological water demand of Baiyangdian Lake is the core problem for ecological restoration, playing a vital role in conserving underground water,maintaining water ecological balance and enhancing regulation of water resources. Based on the ecological demand of Xiong'an New Area, this paper evaluated the ecological water level combining with the relationship between Water level and submerged area. Meanwhile, the ecological water demand of Baiyangdian Lake, including water consumption (e.g. evaporation, infiltration) and the elastic demand to improve the hydrodynamic condition and water ecological environment quality, was proposed. From the perspective of maintaining base flow, the minimum ecological flow of the upstream rivers was calculated, as a basic goal of river ecological restoration. On the basis of this, this paper put forward the ecological water replenishment program and supporting measures, to restore the ecological security of the Baiyangdian Lake and improve the ecological carrying capacity in Xiong'an New Area.
