【摘要】 利用层次分析(AHP)中指数标度法确定相对权重,计算病情指数。依据“等距分级,等比赋值,阶梯跃进”的原则,给出合理的相对权重量化数值,在林业生产中推荐级差α=1.618。更多还原

【Abstract】 The index scale in AHP was used to determine scale-weight and then calculate disease scale.Based on the principle of dividing scale by the same distance,determining data by the same ration,overstepping the ladders,a reasonable data of scale-weight was given.Therefore,the system of α=1.618 was suggested in the forestry practice.更多还原
