摘要: 干旱半干旱地域灌区农业发展,既受水资源短缺制约,又受生态环境和社会因素的影响。论文基于水资源可持续发展的观点,认为灌区水资源优化配置必须考虑经济效益、生态效益和社会效益的协调和综合影响。文中建立了灌区水资源综合效益评价的数学模型。在分析该区水资源利用特点基础上,提出了综合效益评价的经济效益、社会效益和生态效益类等44项评价指标。应用层次分析法(AHP)原理,对构建的模型进行了研究。并以陕西省宝鸡峡灌区为例,利用所建模型进行了综合评价。评价结果可为灌区水资源评价、管理及节水规划提供决策依据。

Abstract: The agricultural development in arid and semi-arid irrigated district depends on water resources,eco-environment and society factors.Research of water resources integrated benefit e-valuation in irrigated area is a core problem concerning development of water-saving agriculture,soil and water environment protection as well as coordinated economic and eco-environmental development.Now adays the evaluation models of water resources mostly use economic benefit maximum as optimized objection function,regardless of social benefit and eco-environmental benefit.Especially research of water resources synthetical benefit in irrigated district is inade-quate.Based on the conception of water resources sustainable development,it is pointed out that water resources optimized allocation should consider economic benefit,eco-environmental benefit and social benefit.Applying analytic hierarchy process(AHP),this paper established the mathe-matical model for integrated benefit evaluation of wa ter resources in irrigated district.The evalu-ation index system is proposed based on characteris tics of water resources development.The eval-uation index system includes3aspects:economic benefit,social benefit and eco-environmental benefit.These indices systematically reflect features in arid and semi -arid irrigated district.Be-cause of the complex relation of indices factors,synthetical benefit evaluation includes quantita-tive and qualitative aspects.The model and indicators made up are applied to evaluate syntheti-cally the status of water resources utilization in Baojixia Irrigated Dis trict in Shaanxi Province.The assessment model played an important role for the evaluation and management of water re-sources and water-saving program in the irrigated district.

Key words: arid and semi-arid district, water resources, analytic hierarchy process(AHP), inte-grated benefit evaluation
