摘　　要：在总结目前国内外湖泊、湿地生态环境需水量计算方法的基础上,针对现有方法存在的问题和适用条件,结合松嫩湿地的特点,确定了相应的计算公式,并依据保护区各功能区划定的原则,确定了最小生态环境需水量的计算方法,并以扎龙湿地自然保护区为例进行了计算。依据45年系列气象数据,对计算结果进行了修正,确定了不同降水频率下湿地的最小生态环境需水量。The calculation methods for the minimum eco-environmental water requirement of lakes and wetlands were investigated based on the internal and international research works, according to the characteristics of the Song-Nen-Plain Wetland. The calculation method of the minimum eco-environmental water requirement was established depending on the partition principle of the protection area for the Song-Nen-Plain Wetland. And a case study was given for Zhalong National Natural Protection Area. The results obtained were revised based on the meteorologic data of 45 years＇ period and the minimum eco-environmental water requirements of Zhalong National Natural Protection Area were calculated under different precipitation frequencies.
