摘　　要：本文在对丹江口库区6县(市)223户农民的问卷调查基础上,以小麦和玉米的种植为例,运用一般线性模型对影响农户氮肥施用强度的因素进行分析,旨在寻找降低农户氮肥施用强度的有效途径。回归结果表明,在小麦和玉米种植上,农户的氮肥施用强度随种植规模的扩大而降低;地域因素对两种作物的氮肥施用都有显著影响,位于河南省的农户氮肥施用强度相对较高;有机肥对氮肥的替代效应不明显,在小麦种植上施有机肥对农户的氮肥施用强度有显著的正效应;农户家庭总收入、劳动力务农机会成本和测土配方施肥对氮肥施用强度没有明显影响;玉米的家庭需求比对氮肥施用强度有显著正效应。Based the survey of 223 farmers of six counties in Danjiangkou Reservoir area, through the general liner model, by the analysis of the farmers＇ nitrogenous fertilizer use on the wheat and eom, this article finds the effective way to reduce the farmers＇ nitrogen use rate. This regression results clarify some influencing relationship of the factors. Nitrogen use rate reduces with the farms＇ production scale on wheat and com. The regional factor has significant effect on wheat and eom and the nitrogenous fertilizer use rate is higher in Henan Province. The organic fertilizer doesn＇ t have the substitution effect to nitrogenous fertilizer furthermore and has significant positive effect on nitrogen use strength during wheat production. The famlers＇ household total income, opportunity cost of agricultural labor and the formula fertilization by soil testing don＇ t have significant effects on the nitrogenous fertilizer use rate of wheat and com. The ratio of the farmer household demanding has a positive significant effect on corn＇ s nitrogen use rate of com.
