本文立足当前塔河流域的成本水价,基于流域主要节水技术成本投入,构建了流域农业节水水价;然后,利用已有研究资料和流域不同作物的水分生产函数,进一步构建了流域农业水价的需求效应模型;分析了未来塔河流域不同农业节水水价的节水效应。研究结果表明:①基于节水水价的未来农业水价的调整可大幅降低灌水量,提高节水效应;②流域水价弹性系数会由缺乏弹性变为富有弹性,这成为流域农业水价调整可行性的一个标志;③不同作物水价需求弹性效应差别很大,这使未来流域农业水价的需求效应分析事关流域粮食安全和用水户的水价承受力问题,成为未来塔河流域农业水价调整研究的重要相关研究内容。
Based on the current cost of water in the Tahe River Basin, this paper builds a water-saving agricultural water-saving price based on the main water-saving technology costs in the basin. Then, using the existing research data and the water production function of different crops in the river basin, Demand effect model, and analyzes the water-saving effect of different agricultural water-saving water prices in the future Tahe River Basin. The results show that: (1) The future adjustment of agricultural water price based on water-saving water price can significantly reduce the amount of irrigation water and increase the water-saving effect; (2) The elasticity of water price elasticity of the river basin will be changed from lack of elasticity to elastic, which becomes a feasibility of agricultural water price adjustment in the basin The elasticity of demand elasticity of different crop water price varies greatly, which makes the analysis of demand effect of agricultural water price in the future river basin be related to food security in water area and the water affordability of water users, and becomes an important research on future agricultural water price adjustment in Tarim River Basin content.
