摘　　要：从理论上分析了兼业农户的时间分配与收入结构变化2个方面对水土保持行为的影响。运用在江西省兴国县、上饶县和余江县的样本村农户调查资料,通过建立农户兼业化发展与农户水土保持行为相互关系Logistic模型,对兼业农户水土保持行为及其区域差异性进行了实证研究。结果表明,从总体样本来看,农户对水土流失的感知情况、非农劳动时间比例、农户受教育水平对农户的水土保持行为影响显著,农户兼业化的发展将使得农户花费更少的时间用在水土保持上。但是由于研究区域社会经济背景及水土流失情况的差异性,兼业农户水土保持行为也存在显著的区域差异性。最后,就进一步推进区域水土流失治理提出了相关建议。The influence of part-time farmer＇s time allocation and income structure on their behaviors of soil and water conservation was theoretically analyzed. A Logistic simulating model was established on the relation between farmer off-farm work and their soil and water conservation behaviors based on the farmer investigation in Xingguo, Shangrao and Yujiang Counties of Jaingxi Province. On the basis of this model, the part-time farmer households＇ behaviors of soil and water conservation and its regional difference were investigated. Results show that farmer households＇ understand on soil and water loss, the proportion of off-farm work time, farmer households＇ education levels significantly influence their soil and water conservation behaviors from the view of population, and farmer households＇ off-farm work does decrease their work time in soil and water conservation. However, because of difference in social and economic condition, and soil and water loss, there are differences among the three sample regions. Finally, there are relative suggestions on how to encounter soil and water loss.
