摘 要:[目的]目前我国水资源短缺,水价长期不能反映水资源稀缺程度,也不利于节水。农业是用水大户,占总用水量60%以上,有巨大节水潜力。工农渠灌区位于甘肃省境内黄河南岸,是西北地区中小型提水灌区典型代表,作为水价改革试点灌区之一,具有一定的代表性。[方法]通过现场调研、统计分析、查阅文献等方式,对工农渠及西北提水灌区农田水利改革现状、供水成本收益、农户水价承受能力、灌区水利用系数和水价政策等方面进行了研究及对比分析。[结果]当前提水灌区水价偏低,有提升空间,计量及末级渠系建设薄弱。[结论]对农业水价综合改革途径进行思考,提出了灌区水价改革要形成科学合理的水价机制,改进了水价补贴政策,配套完善基础设施等相关对策,可为西北提水灌区水价改革达到实效提供参考。[Background]Water scarcity compounded by low agricultural water use efficiency is a great concern in China. Agricultural water price in China has been too low to appreciate its precious value, which is not helpful for improving water using efficiency. Given that agriculture consumes more than 60% of water used by all sectors combined din China, there is a potential to reduce the pressure on demand for water by improving agricultural water use efficiency. Of many methods, reforming agricultural water price is a way to achieve this. Increasing water price would reduce water usage and alert crop cultivation but it could also reduce farmers’ income. How to protect the interest of farmers is a critical issue in reforming agricultural water price.【Objectives】The purpose of this paper is to analyze the consequence of agricultural water price reform by taking Gongnongqu Irrigation District, a typical water-pumping irrigation district in northwest China, as a pilot example. The focus of the water price reform is to rationally reallocate the available water resources to halt a further increase in agricultural water use.[Method]We surveyed 23 pumping stations in the irrigation district and analyzed available data from 2015 to 2017. We then compared the current state of irrigation reform, costs and return of water supply, affordability of farmers, water utilization coefficient and water price policy.[Result]The current water price in the district was low and was largely compensated by the government. There is room for water price increase. Meanwhile, construction of metering network and the final canal system was weak, and should be strengthened.[Conclusion]Comprehensive analysis of the composition of the agricultural water price, water utilization efficiency, affordability of farmers and other factors, revealed that it is necessary to reform water price in the irrigation district by improving the policy subsidizing water, infrastructure and other related countermeasures.
