基于2007—2018年长江流域和黄河流域19个省份的数据，在分别测度各省份农业生态效率和农旅融合水平的基础上，基于线性和非线性模型检验了农旅融合对农业生态效率的影响。结果表明：农旅融合发展水平对于农业生态效率提升具有显着正向影响，且这种影响呈现显着的非线性门槛特征，其强度变化与农旅融合发展水平呈正相关；农旅融合发展对农业生态效率的影响效应呈现一定的区域差异性，长江流域省份农旅融合发展对农业生态效率的正向提升效应要强于整个研究区和黄河流域省份；农业生产要素投入中，农业劳动力、农作物播种面积、有效灌溉面积、农药、化肥等投入均随融合水平的不断提升而相应减少，农业机械总动力投入随融合水平上升呈现先增后减的趋势。

The impact of agricultural tourism integration on agricultural ecological efficiency is examined with the linear and non-linear models based on the data of 19 provinces in the Yangtze River Basin and the Yellow River Basin from 2007 to 2018 and respective measurement of agricultural ecological efficiency and agriculture-tourism integration in each province. The results show that the integration of agriculture and tourism has a significant positive effect on the improvement of agricultural eco-efficiency, with a significant nonlinear threshold feature, and its intensity changes positively correlated with the integrated development of agriculture and tourism. Regional differences can be found in the impact of integrated agricultural tourism development on agricultural eco-efficiency .Positive effects of integrated agricultural tourism development on agricultural eco-efficiency in the provinces of the Yangtze River Basin are stronger than those of the whole research area and the provinces in the Yellow River Basin. The input of agricultural labor force, crop sown areas, effective irrigation areas, pesticides and chemical fertilizers among agricultural production factors decreases with the continuous improvement of the integration , while the total power input of agricultural machinery is liable to increase first and then decrease with the rise in the integration .
