摘　　要：对1999~2012年黄河水量统一调度期间宁夏河段引水和退水的年内和年际变化、引排比关系进行了分析。采用引退水法和水量平衡法计算了宁夏河段的引黄耗水量。结果表明:引退水法平均耗水量为32.64×10~8m^3,年际变化相对比较平缓;水量平衡法平均耗水量为39.37×10~8m^3,年际变化非常明显。建议进一步加强实际引退水口门的数量核实和引退水的监测分析工作。The annual allocation, inter-annual variation and relation of water diversion and water recession were analyzed for the period during 1999-2012 of the Yellow River integrated water regulation in the Ningxia reach. Water consumption in the Ningxia reach was calculated with the methods of water diversion-recession and water balance. The mean water consumption from water diversion-recession method is 3.264 billion m^3 and annual variability of which is relatively flat. The result of water balance method is 3.937 billion m^3 and annual variation is obvious.
