摘要
本文依据宁南山区雨养农业区的自然、社会、经济条件，建立了对该区作物立体复合种植效益进行综合评价的指标体系，并采用多层次决策分析法（ＡＨＰ）对各种立体复合种植模式和相应作物的单一种植系统进行了效益的综合分析和评价。提出了该区在目前生产力状况下优化的立体复合种植模式，即：马铃薯＋蚕豆、小麦／马铃薯、豌豆／玉米、胡麻／玉米。这４种立体复合种植模式可在当地不同气候类型区大面积推广应用。
In accordance with the natural, social and economical conditions of the ralnfed farming areas in the Hilly Southern Ningxia, the. index system was built for an integrated appraisal on crop-interplanting benefits in the areas, and the Analytic Hierarchy Process(A HP) was adopted in analysing and evaluating corn prehensiyely the effects and benefits of various crop-interplanting patterns and the corresponding crop-monoculture system. In the circumstances of present productiyity the optimum interplanting patterns were raised for the rainfed farming areas,namely, potato-broadbean, wheat-potato, Pea-maize and flax-maize interplanting patterns. The 4 patterns can be extended over large areas in different climate types in the locality.
