基于AHP-熵权法的农业节水技术综合效益评价
|
摘要
AHP法和熵权法分别被广泛应用于农业节水灌溉技术综合评价中,AHP法注重主观经验,熵权法注重客观规律。为此,将两种方法相结合用于评价农业节水灌溉技术综合效益,从经济、生态、社会3个效益维度构建了农业节水灌溉技术综合效益评价指标体系,用MatLab软件计算由AHP-熵权法确定的综合权重值,应用线性加权法实现不同节水灌溉技术的综合效益测度。结果表明:评价中的3种节水灌溉技术综合效益测度值为膜下滴灌+暗管排水技术(0.665)>膜下滴灌(0.566)>传统漫灌技术(0. 324);膜下滴灌+暗管排水技术不仅增加玉米产量以及农民收入贡献率,而且有助于解决实验基地存在的干旱缺水、土壤盐碱化等生态环境问题;采用AHP-熵权法能够选出综合效益最佳的农业节水灌溉技术。
AHP method and Entropy Weight method are widely used in comprehensive benefit evaluation research of agricultural water-saving irrigation technology,respectively. As AHP attaches more importance on subjective experience and Entropy Weight method emphasizes on objective law,these two methods are combined for the comprehensive benefit evaluation of agricultural water-saving irrigation technology in this study. The comprehensive benefit evaluation index system of agricultural water-saving irrigation technology is constructed by three benefits dimensions of economic,ecological and social. Take the water-saving irrigation Experimental Site in Qianguo County,Jilin Province as an Example. Matlab is applied to calculate the combined weight value determined by AHP-Entropy method,and linear weighting method is applied to achieve comprehensive benefit measurement. The results show that the comprehensive benefit values of three agricultural water-saving irrigation technologies in the evaluation,are drip irrigation under film and subsurface tube drainage technology( 0.665) > drip irrigation under film technology( 0.557) > Tradition flood irrigation technology( 0.324). The drip irrigation under film and subsurface tube drainage technology not only increases the yield of corn and income of farmers,but also improves the ecological environment such as drought and water shortage,soil salinization in Qianguo County,Songyuan,Jilin Province. The AHP-entropy method can be used to select the best agricultural water-saving irrigation technology for farmers and agricultural departments.
