银川平原艾依河湿地生态水平衡研究

通过对艾依河水量平衡影响因素作用方式的系统分析,建立适宜的水量平衡方程,测算维持艾依河现有湿地格局和规模的基本需水量。以城市河湖生态需水理论为依据,测算水面蒸发需水量、换水需水量、河道输水损失量、渗透需水量和河道基流量,得出维持艾依河湿地生态健康的生态需水量。

Studies on ecological water balance of Aiyi River Wetlands in Yinchuan Plain

In order to set up a water balance equation and estimate water demand to sustain the current status of wetlands of Aiyi River, a systematic analysis on the factors that influence water balance is made. On the basis of theory of water demand of river and lake ecology, estimations are conducted for water demand of evaporation of water surface, water changing, water conveyance loss, seepage and base flow of river course.Ecological water demand for sustaining health of wetlands is obtained accordingly.
