柴达木盆地德令哈灌区典型地块小麦灌溉用水量监测试验与分析

Test and Analysis on Wheat Irrigation Water Monitoring of Typical Plot in Delingha Irrigation Area of Qaidam Basin

柴达木盆地幅员辽阔,矿产资源丰富,但水资源匮乏是其经济发展的"瓶颈"之一。2014年柴达木盆地用水总量为9.88亿m^3,其中农业用水量占85.6%,节约用水潜力较大。根据柴达木盆地德令哈灌区典型地块小麦灌溉用水量的监测试验,发现小麦种植灌溉用水量远低于该地区相关统计数据,渠道渗漏和管理粗放是传统小麦种植用水效率较低的主要原因,可以考虑通过提高渠道衬砌率和强化灌溉管理等方式来提高用水效率。

Qaidam Basin has a vast territory and rich in mineral resources,but water shortage is one of the ＂ bottlenecks＂ of economic development. In 2014,the total water consumption in Qaidam Basin was 988 million m^3,the agricultural water consumption was 85. 6% and the water conservation was potential. According to the monitoring test of wheat irrigation water consumption in the typical land area of the typical land in the Delingha irrigation area in Qaidam Basin. It was found that the water consumption of wheat cultivation was much less than the statistical data was calculated. The main reasons for the low efficiency of traditional wheat cultivation were the canal seepage and extensive management,which can be considered to improve the efficiency of water use by improving the channel lining rate and strengthening irrigation management.
