中文摘要：

基于塔里木河流域主要水价调整年份的农业水价和相应的灌水量资料,分析了塔里木河流域农业水价调整的节水效应和水价调整的需求弹性;构建了塔里木河流域农业水价调整的需求效应模型,基于成本水价和调整的需求弹性系数,分析了农业成本水价对灌水量的效应。结果表明,尽管塔里木河流域农业水价调整的需求弹性很小,但可促进初期灌水量大幅降低;流域内水资源丰富、利用率低的源流和干流上游农业水价调整的需求弹性高;与单纯提高水价到成本价比较,同时提高水价需求弹性系数对灌水量的节水效应更大。

英文摘要：

According to the materials of the different water price and the quantity of irrigational water, the paper analyzes the effect of adjustment of agricultural water price on the quantity of irrigational water in Tarim river basin and further makes its model, and uses it to give an analysis for the effect of water price on the basis of agricultural cost water price and adjusted elastically parameter of demand of water price. The results indicates as follows, the elasticity of water price is very little, but its effect on the quantity of irrigational water is relatively great in the pri- mary period. The elasticity of water price is relatively high in the Tarim river basin that water resource is plentiful, and its utilization ratio is relative low. It is more effective on the quantity of irrigational water to improve water price to the cost price and use adjusted elastically parameter of demand of water price by comparison with the adjustment of cost water price respectively.
