摘要
为提升水利行业管理和技术人员对甘肃省农业灌溉用水定额修编的理解,合理配置水资源,提高农业灌溉用水利用效率和效益。基于《甘肃省行业用水定额(2022版)》,结合甘肃省农业经济发展水平、农业产业结构调整趋势以及涉水相关规程规范对水利工程供水保证率的要求,规范了农业灌溉用水定额行业编码,明确和补充了农业灌溉用水定额术语和定义,将甘肃省原有5个农业灌溉分区重新划分为12个;综合甘肃省气候资源、水资源、地形地貌和农作物种植布局,依托甘肃省灌溉试验站点、国家级气象监测点和灌区内农业科研试验平台,借助气象、水文、土壤和作物数据,确定了水源类型调节系数和通用值与先进值之间的折算系数,分析了不同设计灌溉供水保证率条件下主要作物的灌溉制度,给出了甘肃省55种主要作物灌溉用水定额。并对比分析了国家和相邻省份最新农业灌溉用水定额修编成果,对甘肃省修编成果进行了修正。评价结果表明,《甘肃省行业用水定额(2022版)》在覆盖性、合理性、实用性和先进性等方面均有较显著改善,但鉴于农业灌溉用水定额具有动态性、确定性、差异性、强制性等特点,以及现状条件诸多约束和农业产业布局等要素变化,仍存在优化空间,有必要按需求和规范进行滚动修编。
The aim of this paper is to improve the understanding of water conservancy industry management and technical personnel on the re⁃vision of agricultural quota of irrigation water in Gansu Province,rationally allocate water resource,and improve the efficiency and benefit of agricultural irrigation water utilization.Based on the“Industrial Water Quota in Gansu Province(2022 Edition)”,this paper standardizes the industry code of agricultural quota of irrigation water,clarifies and supplemented the terms and definitions of agricultural quota of irriga⁃tion water,and redivided the original 5 agricultural irrigation subdivisions in Gansu Province into 12 by considering the level of agricultural economic development in the province,the trend of agricultural industrial structure adjustment,as well as regulations and requirements to meet the current and future demand of water resources.The analysis is based on the climatic resources,water resources,topography and crop planting layout of Gansu Province by using data measured from irrigation experimental stations and weather monitoring stations.This paper calculates the scientific research experimental platform of agricultural in the irrigation area,with the help of a series of meteorological,hydrological,soil and crop data,the adjustment coefficient of water source type and the conversion coefficient between the general value and the advanced value is determined,the irrigation system of the main crops under the condition of different designs of irrigation water supply guarantee rate is analyzed,at the same time the quota of irrigation water of 55 main crops in Gansu Province has been given.And we com⁃pared and analyzed the latest revision results of the state and neighboring provinces to modify it again.The results show that the coverage,ra⁃tional,advanced and progressive of the conclusion is improved obviously.However,it is still necessary to revise the result at the right mo⁃ment because of the dynamic,certain,different,mandatory and other characteristics of
