摘要
耕作制度涉及的内容广泛.既有单作、复种,又有间作、套作和混作.而且耕作制度所含作物种类繁多,产品形式多种多样.应用一系列评价指标进行分析对比,或用综合评分法,都会给耕作制度的效益评价与分析带来一定的困难.本文介绍了应用层次分析法(Analytical HierachyProcess,简称 AHP),计算耕作制度的效益评价体系中各项指标的权重以及应用模糊综合评价进行耕作制度综合效益评估的方法.并将该方法应用到红壤旱地多熟方式的评价中去,取得较满意的效果.笔者认为,这是耕作制度定性与定量研究的一次新探讨。
Farming system includs not only sole cropping,sequence cropping butalso intercropping,relaycropping and mixed cropping.In one kind of plantcropping system(or farming system),there are often many kinds of cropswhich have different forms of yield organs.The traditional methods such asanalysis-contrast method with a series of indexes and comprehensive markingmethod may cause some difficulties in the evaluation of farming systems.Thispaper gives a detailed introduction of the application of Analytical HierarchyProcess(AHP)to determine the weights of a series of indexes in the evalua-tion of farming systems.It also deals briefly with the method of fuzzy com-prehensive evaluation and its utilization in farming system analysis.Whatthe authors do is a significant approach to the quantitative evaluation offarming systems.
