摘要
本文提出了用于节水灌溉方式优化选择的项目综合评价方法 .运用层次分析理论和方法 ,建立了综合考虑项目的国民经济评价、技术评价和社会评价以及内部收益率、净现值、效益费用比、投资回收期、灌水均匀度、灌水强度、灌溉水利用率、节水灌溉方式的安全性、可靠性、地形适应性、作物的适应性、施工难易程度等因素的节水灌溉方式选择的层次分析模型 ,阐述了综合评价节水灌溉方式的总排序。
The method for synthetical evaluation of optimal choice on water saving irrigation mode is presented. The analytic hierarchy process(AHP) theory is applied and the following factors are taken into account:the national economic evaluation, the technical evaluation and the social evaluation of a project, internal rate of return; net present value, benefit to cost ratio, period of investment return, the uniformity of irrigation, the intensity of irrigation, rate of irrigation water used, the security and reliability of the water saving irrigation mode, the adaptability of landforms, the adaptability of crops, the popularity with the farmers and the difficulty in construction. This paper also deals with the general compositor and the single compositor of evaluating the mode of water saving irrigation and calculating method of the weights of the correlated factors.
