摘　　要：采用湖泊形态法、生态水文法、天然水位资料法和生物最小空间需求法等4种方法分别计算了洪湖湿地最低生态水位,计算结果分别为23.8 m2、3.64 m2、3.24 m和23.5 m。通过对4种计算方法和结果的比较分析,认为由生态水文法确定的洪湖最低生态水位23.64 m比较合理,且通过该方法可以计算洪湖逐月最低生态水位,分别为23.69 m,23.64 m,23.69 m,23.63 m,23.69 m,23.89 m,24.57 m,24.89 m,25.00 m,24.63 m,24.16 m,23.86 m,这些水位值可以为洪湖湿地分时段水位调控提供参考。The minimal ecological water level of Honghu Lake was studied and calculated by using the lake morphology analytic approach, the ecological water level method, the natural water level data method and the lowest space demand method of biology. The calculation results were 23.8 m33.64 m,23.24 m and 23.5 m, respectively. By comparing the four results, the water level 23.64 m calculated by the ecological water level method was considered as the minimal ecological water level of Honghu Lake. And also the minimal ecological water level of every month in a year could be calculated by the method. The results were 23.69 m, 23.64 m, 23.69 m, 23.63 m, 23.69 m, 23.89 m, 24.57 m, 24.89 m, 25.00 m, 24.63 m, 24.16 m and 23.86 m.
