摘要： 针对黄土高原地区雨水资源开发利用现状和小流域雨水资源化特点,以小流域作为研究单元,以雨水资源作为研究对象,借鉴层次分析法(AHP)原理,遵循科学、实用及其简明的原则,构建小流域雨水资源化综合效益评价数学模型,提出了综合效益评价的经济效益、生态效益和社会效益等32项评价指标。并以陕西省淳化县泥河沟小流域为例,利用所建模型进行了综合评价。评价结果可为黄土高原雨水资源高效利用和生态环境健康发展提供理论依据。

Abstract: Rainwater resources utilization is an effective measure for solving wa ter resources shortage and eco,environmental rehabilitation in Loess Plateau of China.Research of rainwater resources integrated benefit evaluation is a core pr oblem concerning development of dryland agriculture,soil and water environmental protection as well as coordinated economic and eco,environmental development.No wadays the evaluation models and indicators system of rainwater resources mostly use economic benefit maximum as optimized objection function,regardless of soci al benefit and eco,environmental benefit.Especially research of rainwater resour ces integrated benefit in Loess Plateau is inadequate.Based on the current situa tion of rainwater resources utilization and the characteristic of converting rai nwater into rainwater resources,applying analytic hierarchical process theory,th is paper establishes the mathematical model and indicators system for integrated benefit evaluation of rainwater resources utilization by taking small watershed as a research unit and rainwater resources as a research object.The evaluation indicators system is proposed based on characteristics and principles of scienti fic,practical and concise.The indicators system includes three aspects such as e conomic benefit,social benefit and eco,environmental benefit and systematically reflects rainwater resources utilization features in small watershed.Because of the complex relation of indicators factors,synthetically benefit evaluation incl udes quantitative and qualitative aspects.The evaluating model and the indicator s system are applied to evaluate synthetically the status of rainwater resources utilization in Nihegou watershed in Shaanxi Province.The evaluation model playe d an important role in the evaluation and management of rainwater resources sust ainable utilization and eco,environment construction on the Loess Plateau.

Key words: small watershed, rainwater resources, integrated benefit, indicators system, evalua,ting model
