摘　　要：近年来,农业生产中过量施肥问题越来越严重,研究农户对过量施肥负效应的认知对控制化肥施用量具有重要意义.本文采用结构方程模型(SEM),基于三峡库区南沱镇的调查问卷数据,实证分析了农户对过量施肥负效应认知的影响因素.结果表明:当地农户文化程度普遍不高,基本处于初中文化水平;农户比较关心先进农业信息技术,但是当地政府和农技部门对先进农业信息技术的宣传和推广力度不够.家庭特征和环境意识对过量施肥负面效应的认知有一定影响,但是影响不是很大,农技培训对过量施肥负面效应的认知的影响分析具有统计学意义.因此,加强农业技术培训,定期开展农业技术信息宣传对控制农户施肥量具有积极作用.In recent years, excessive application of fertilizer in agricultural production is becoming increasingly serious. Farmers＇ cognition of the negative effects of excessive fertilization is of great significance to controlling chemical fertilizer consumption. In a study reported in this paper, based on the questionnaire data of Nantuo town in the Three Gorges Reservoir Area, the structural equation model （SEM） was used to make an empirical analysis of the influencing factors for farmers＇ cognition of the negative effects of excessive fertilization. The results showed that the local farmers＇ education background was, on the whole, not good enough, basically being at a junior high school level. Farmers appeared interested in the advanced agricultural information technology, but the local government and agricultural technology department failed to do a good job in its dissemination and promotion. Family characteristics and environmental con- sciousness of excessive fertilization of the farmers had but insignificant effects on their cognition of the negative effects of excessive fertilization, while agricultural technology training had a great influence on it. It is, therefore, concluded that agricultural technology training should be strengthened and publicity and dissemination of agricultural technical information should be made on a regular basis, so that the farmer households may control their chemical fertilizer consumption.
