摘　　要：为了解丹江口水库生态敏感区内影响农户施肥行为的主要因素,以贾营小流域为例,采用参与式农村调查与评估(PRA)法,对贾营小流域201个农户进行施肥行为调查访谈,并运用回归模型分析了农户基本情况、土地经营情况、经济水平及地理区位特征对农户施肥行为的影响。研究结果表明:耕地复种指数和家庭非农收入与化肥施用强度成显著正相关关系;家庭距乡镇中心距离与化肥施用强度成显著负相关关系。建议根据不同土壤类型,因地制宜调整施肥模式;调整农业经营模式,将农业粗放型经营转换为精细化、专业化经营,推动农业经营产业化和规模化;加强农村基础设施建设。In order to understand the main factors that affect farmer＇s fertilization in the eco-sensitive areas of Danjiangkou Reservoir, taking Jiaying small watershed as an example, based on the Participatory Rural Appraisal （PRA）, this study investigated 201 farmers＇ fertilizer application behaviors in Jiaying watershed. It analyzed the effects of the basic characteristics of farmers, the characteristics of the land, the economic level features and the geographic area characteristics of the farmer＇s fertilized behavior by using the regression model. The results show that the yield of cultivated land and non-agricultural income are positively correlated with the intensity of fertilizer application and the test effect is significant. The distance between the family distance from the town center and the intensity of chemical fertilizer application shows a significant negative correlation. According to the above conclusions, it suggests to adjust the fertilization mode according to different soil types, adjust the agricultural operation mode, transform agricultural extensive operation into fine and specialized operation, promote the industrialization and scale of agricultural operation and strengthen rural road construction and improve the construction of rural infrastructure.
