中文摘要：

从支付能力的角度定量研究农民对灌溉水价的承受能力，采用扩展线性支出系统（ELES）模型，通过实例计算分析了农户总体收支及水费支出、农民基本消费需求支出和支付能力水平的界定标准等，并分析了支付能力的主要影响因素。结果表明：研究区域内农民年人均纯收入774元和1300元是支付能力水平的分界线，无支付能力、有一定支付能力和有支付能力的农户分别占6．1％、9．7％和84．2％；支付能力较低的农户均以农业生产为主要收入来源；不同支付能力组之间农民年人均水费支出与平均水费支出均无显著差异；耕地面积、农业收入和非农业收入对农民支付能力具有显著的影响。

英文摘要：

The farmers＇ bearing capacity for irrigation water price is quantitatively estimated from the aspect of payment ability. Through a case study, the Extended Linear Expenditure System （ELES） model is applied to calculate the farmers＇ general income and expenses, payment for irrigation water use, expenditures of basic consumption demand, and the levels of farmers＇ payment ability. Also, the major influence factors of payment ability are analyzed. The result shows that that 774 Yuan and 1,300 Yuan of the rural per capita net income are the boundary among the three levels, namely without payment ability, with certain payment ability and with payment ability, of which the percentage is 6.1%, 9.7 % and 84.2 %, respectively. Agricultural production is the main source of income for the farmers with lower payment ability. The rural per capita or per unit area payments for irrigation water use among the three level groups have not remarkable differences. The cultivated area, agricultural income and non-agricultural income are the three main influence factors for farmers＇ payment ability.
