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。 |

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. Nowadays 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 inadequate. Based on the conception of water resources sustainable developmental 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 mathematical model for integrated benefit evaluation of water resources in irrigated district. The evaluation index system is proposed based on characteristics of water resources development.The evaluation index system includes 3 aspects: economic benefit, social benefit and eco-environmental benefit. These indices systematically reflect features in arid and semi-arid irrigated district. Because of the complex relation of indices factors, synthetical benefit evaluation includes quantitative and qualitative aspects. The model and indicators made up are applied to evaluate synthetically the status of water resources utilization in Baojixia Irrigated District in Shaanxi Province. The assessment model played an important role for the evaluation and management of water resources and water-saving program in the irrigated district. |
