| 摘 要： | 以天津七里海湿地为研究对象，按照七里海湿地生态系统的结构特征和生态功能，把生态需水量划分为湿地水面蒸发消耗需水、湿地植物需水、湿地渗透消耗需水、湿地土壤需水和湿地生物栖息地需水5个组成部分。对各部分需水量进行计算，确定七里海湿地最适生态需水量为3272．365万m^3／a。

| Abstract: | Based on the structural characteristics and ecological functions of Qilihai Wetland in Tianjin, its ecological water requirement was divided into five parts including water requirement of water surface evaporation, water requirement of wetland plant, water requirement of infiltration, water requirement of wetland soil and water requirement of biological habitat. According to the calculation results of each part, the most proper ecological water requirement of wetland was 3. 272 365× 10^7 m^3. |
