入淀水量不足,是造成白洋淀湿地生态及其环境恶化,淀泊萎缩的重要原因,如何修复已遭破坏的白洋淀湿地生态系统,并维护湿地的生态平衡是亟待解决的重要问题.本研究采用白洋淀湿地从1956-2000年的逐月实测水位数据,通过分析汛期和非汛期的水位经验频率以及白洋淀湿地的生态功能,确定了白洋淀周年的生态适宜水位范围为7.9～8.7 m.当白洋淀出现生态干旱,水位不能维持在7.9～8.7 m时,生态补水后应使淀水位保持在7.1～7.9 m范围内.本文从补水量和补水时间2个方面,对白洋淀湿地的生态补水方案进行了研究.

Baiyangdian is the largest wetland in north China. The hydrological data of precipitation,feeding flow to Baiyangdian Wetland,and water level since 1956 have been analyzed for Baiyangdian Wetland. Through analysis of water level occurrence frequency in high-water and low-water seasons and in light of actual circumstances,the suitable water level for ecosystems of Baiyangdian Wetland has been determined. The result show that the annually best ecological water level ranges between 7 9-8 7 m. When ecological drought occurs and the water level falls out of the range,ecological water level after water has been added should be kept between 7 1-7 9 m.
