摘　　要：基于《甘肃省行业用水定额(2023版)》编制工作,通过实地走访调查获得2018—2020年典型灌区棉花灌溉用水量和有关种植资料,采用面积加权法和类比法分析确定了甘肃省棉花灌溉用水定额。结果表明,甘肃省棉花种植主产区集中在河西走廊内陆河的中下游,棉花灌溉用水定额为540~610m^(3)/亩。此次棉花灌溉用水定额修订后,其覆盖性、实用性、合理性、先进性均有所改善,符合国家节水政策,能够为甘肃省未来农业高效节水发展提供重要的数据支撑。Based on the compilation work of Water Quota for Industrial Use in Gansu Province(2023 Edition),the revision and evaluation of water quota for cotton irrigation in Gansu Province are conducted.Through field visits and investigations,the typical water consumption for cotton irrigation in the period from 2018 to 2020,as well as relevant cultivation data,are obtained.The water quota for cotton irrigation in Gansu Province is determined using the weighted area method and analogy method.The results show that the main cotton production areas in Gansu Province are concentrated in the middle and lower reaches of the inland rivers in the Hexi Corridor,with a water quota for cotton irrigation ranging from 540 to 610 cubic meters per mu(approximately 0.165 acres).After the revision of the water quota for cotton irrigation,its coverage,practicality,rationality,and advancement have all been improved,in line with national water-saving policies.It can provide important data support for the future development of efficient and water-saving agriculture in Gansu Province.
