摘要
简单介绍了湿地生态环境需水量的概念及其特点,详细分析了目前常用的关于湿地基本生态环境需水量的计算方法,经过优缺点对比,选取了适当的生态环境需水量计算方法和自然湿地生态用水需求预测参数,并对河北省现有自然湿地逐一进行了近期、中期和远期的生态环境需水量测算。测算结果对今后河北省湿地水资源节约,水资源利用率提高,河流污染控制,生态环境改善具有重要的理论意义和实用价值。
The authors simply discussed the concept and its characteristics of wetland eco-environmental water requirement. It analyzed the eco-environmental water requirement on water balance method. In contrast, appropriate method is chosen to calculate eco-environmental water requirement. Then the authors tested eco-environmental water requirement on short, middle and long time in Hebei. Its consequence has important significance on saving water, improving water exploitation, controlling pollution and ameliorating eco-environment.
