基于区域的水量平衡理论,对宁夏引黄灌区的广义生态耗水量进行计算,同时对灌区生态耗水量与灌区引黄水量的关系也进行了研究。研究结果表明:灌区各年的广义生态耗水总量差别并不大,没有表现出非常强烈的上升或下降趋势,耗水量的小范围变动与灌区引黄水量关系不明显。
Based on water balance equation theory, generic ecological water consumption in the Ningxia Yellow River Irrigation Areas was calculated. Through the change of the regional broad sense ecological water consumption in the last several years, the change law of regional ecosystem was reflected, meanwhile, the relation between the ecological water consumption and water diverted from the Yelow River was researched. The researched result shows that the annual differences of generic ecological water consumption were little, and the relation between the narrow range change of generic ecological water consumption and water diverted from the Yelow River is not sensitive.
