Based on field investigation,trace recording,and experimental data analysis,ecological economic principles are applied to study ecological economic benefit of fruit-pig-methane compound management mode in the southern loess hilly gully region.The results indicate that the mode can ameliorate soil in a certain degree and increase soil porosity and the contents of soil nutrients.It can also increase the percentage of excellent and commodity fruit and reduce the percentage of abnormal fruit and the times of diseases and pests.The mode can increase renewable biogas energy,so it can reduce fossil fuel demand and protect environment.The mode has a great economic value.It can increase rural people's incomes and the economic benefit of apple orchard.In a word,the fruit-pig-methane compound management mode has a great eco-economic benefit and may make great contributions in new rural reconstruction.
