摘    要:由于衡水湖流域上游建设了大量水利工程,使衡水湖入湖水量逐年减少,最终导致干涸。自2000年河北省政府批准建立衡水湖省级自然保护区,由外流域调水与本地水资源联合调度水资源,开始实施对衡水湖湿地的恢复。通过对衡水湖湿地生态系统恢复的原则、原理和方法进行分析,衡水湖湿地生态恢复方法采用外流域调水补充水源、利用水生植物控制湿地营养物质的措施、利用种子库、植物繁殖体等途径恢复植被等措施。确定恢复目标为恢复湿地功能、保护野生动物、恢复传统景观等,并对恢复后的衡水湖生物多样性进行评价,探讨湿地恢复过程中的具体问题,为北方干旱地区湿地生态恢复提供参考依据。

关 键 词:湿地生态恢复方法  湿地恢复目标  功能评价  衡水湖

Abstract:Because there are a larger number of water conservancy project built in upstream drainage area of Hengshui Lake, the entering water volume reduced generally, and finally dried up.This paper analyzed the principle and means of recovering ecosystem of Hengshui Lake wetlands by using outer drainage area to supply water, using water plant to control marsh nutriment, using seed storeroom, using plant breeding body and so on.The objective of recovering was to renew the marsh function, protect wild animals, and to recover traditional landscape and so on.The bio-diversity of the recovered Hengshui Lake was evaluated, and the concrete questions about the recovery of marsh were discussed, which could offer the reference for the marsh ecosystem recovery of the northern drought areas.
Keywords:restoration approach of wetland ecosystem  wetland restoration goals  function evaluation  Hengshui Lake
