摘要
文章利用江西省2028份农户调查数据，运用增强回归树（BRT）模型分析衣户环保行为决策的影响因素。结果表明：（1）总体上，农户在农业生产中，采取的环保行为程度较差；（2）农户的环保行为决策主要受到耕地资源特征和个人特征的影响，g-gt特征次之，生态环境认知特征最弱；（3）年龄、耕地破碎度、实际耕种面积、农业收入比重是影响农户环保行为的主要影响因素，文化程度、衣业收入比重、实际耕种面积、农业面源污染的认知和水环境恶化的认知对农户环保行为决策具有正向作用，而耕地破碎度具有负向作用。
Based on the survey data of 2 028 farmers in Jiangxi Province, the booted regression tree （BRT） models was applied in this paper to analyze the influencing factors of farmers＇ decision-making of environmental behavior. The results showed that： （1） On the whole, the farmers＇ environmental protect behavior is poor. （2） The farmers＇ environmental protect behavior is mainly influenced by the characteristics of cultivated land and the characteristics of the individual, the family characteristics do the less, the ecological environment cognition characteristics do the least. （3） The main factors of farmers＇ environmental protect behavior are the age, cultivated land fragmentation, the actual farming area and the proportion of agricultural income. The degree of education, the proportion of agricultural income, the actual farming area, the cognition of agricultural non-point source pollution and the deterioration of water environment have positive effect on farmers＇ environmental protect behavior, and the cultivated land fragmentation does the contrary.
