| 摘 要： | 应用平原区水循环模拟模型,结合宁夏平原区未来农业发展方向,分析宁夏平原种植结构调整下农业对黄河水量的取用和消耗状况。结果表明:(1)在广义水资源利用过程中,黄河水资源耗用量占75%以上,黄河是宁夏平原区重要的支撑水源;(2)种植结构调整力度的增强可提高耗黄水量在引黄水量中的比重,而农业对黄河水量的实际消耗仅为45%,水资源有效利用率较低;(3)水稻和套种是农业耗黄水量的主力,两者面积的大幅度减少有助于水资源取用量和消耗量的节约,但耗水节水量远小于取用水节水量。

| Abstract: | In this paper,the water cycle simulation model was applied to analyze the changes of water supply and water consumption of Yellow River induced by plant structure adjustment.The results show that the Yellow River is the main water source for plain area of Ningxia;the strengthen of planting adjustment increases the ratio of Yellow River water consumption,and water consumption for agriculture is only 45 percent;the reduce of paddy rice and interplanting area is contributed to save water intaking and consumption,but the consumption is less than intaking. |
