摘　　要：本文在论述浙江省粮食产后技术系统现状和特点的基础上,根据浙江省金华、嘉兴、宁波三个试验基点的调查和测定结果,从产后粮食损失、处理成本投入、系统处理效率和粮食品质变化四个方面,用多层次综合评判方法,对现行的三种粮食产后技术系统模式进行了综合评判和灵敏度分析,并提出了相应的改进模式,分析结果表明,与现行模式相比,改进后的相应模式具有更好的综合效益,文中还指出了各种模式的适用条件,为各地合理选用、完善和改进粮食产后技术系统提供了依据。On the basis of analysis of present situation and characteristics on grain postpro-duction system,according to a series of field trials and survey in Jinhua,Jiaxin and Ningbo,Zhejiang Province,a model of multifactorial evaluations was used to assess three basic grain postproduction system patterns prevailing in Zhejiang Province using four components,i.e.postproduction cost,treatment efficiency,grain quantity loss and grain quality deterioration.Sensitive analysis was undertaken for the results of assessment.On the basis of assessment,three improved grain postproduction system patterns were put forward,and comparison analysis between three improved patterns and three present patterns showed that the improved patterns have lower cost,higher efficiency,less losses,better quality indexes and higher rate of benefit to cost.The adaptability of three improved patterns were also discussed in this paper.
