WJQ灌区农业用水利用率及节水灌溉分析

Analysis of agricultural water utilization rate and design of water-saving irrigation in WJQ Irrigation Area

随着新疆地区经济的发展,各类灌区规模也在不断扩大,随之而来的用水矛盾越来越突出。以新疆WJQ灌区为实例,通过灌区用水率分析,得出该灌区平均农业用水利用率0.388,节水潜力巨大;通过对灌区水资源供需平衡分析,灌溉用水缺口305万m^3,对此实施节水改造,为类似工程提供必要的技术参考。

With the development of economy in Xinjiang,the scale of all kinds of irrigation districts is expanding,and the contradiction of water use is becoming more and more prominent. Taking Xinjiang WJQ irrigation area as an example,through the analysis of water use rate in irrigation area,the paper draws a conclusion that the average utilization rate of agricultural water in this irrigation area is only 0.388,and the water saving potential is huge. Through the analysis of water supply and demand balance in the irrigation area,the gap of irrigation water is about 3.05 million m3. The implementation of water saving transformation can provide necessary technical reference for similar projects in the future.
