摘要
采用极值无量纲化法处理辽宁省2008-2017年农业用水效率指标初始值,并对各项指标权重利用奇异值分解的AHP法求解,将规范化处理后的数值输入改进的AHP模糊物元模型,从而更加显著的反映研究期间用水效率差异。结果表明:辽宁省农业用水效率存在较大的节水潜力,综合评价结果呈波动上升趋势,对于农业用水效率的评价模糊物元模型具有良好的适用性与可行性。
The extreme value dimensionless method was used to treat the initial value of agricultural water efficiency index in Liaoning Province from 2008 to 2017,and the weights of each index were solved by using the AHP method of singular value decomposition,and the normalized values were input into the improved AHP fuzzy matter-element model,so as to more significantly reflect the difference in water efficiency during the research period.The results show that:the agricultural water use efficiency in Liaoning Province has great water-saving potential,and the comprehensive evaluation results show a rising trend of fluctuation,so the fuzzy matter-element model for the evaluation of agricultural water use efficiency has good applicability and feasibility.
