摘　　要：本文讨论了作物产量构成因素通径分析的方法。提出按因果关系将各因素对产量的效应剖分为多个路段，并进而计算与比较其效应总和及总决定程度。在各因素的变异较大时，对数转换后再进行通径分析才合理。In this paper, the path analysis method of compositive factors of crop yield was discussed. It was put forward that the effect of every factor to yield was resolved into several routes according to the relationship of cause and effect, and then the total of effect and the total decided level of every factor to yield were calculated and compared. When the variation of every factor was bigger, it was reasonable that logarithmic transformation must be used before path analysis.
