%X This paper studies the agroforestry systems on slopes from the biomass and productivity, the energy conversion rate,the utilization rate of nutrient elements and the efficiency of value conversion.Moreover the comprehensive benefits of them are evaluated by using the AHP.The results show that in comparison with the farmland system,the agroforestry systems have the accumulative effect of biomass,energy,nutrient elements and value,and larger productive potential.Also the economic benefit and the utilization rate of auxiliary energy,solar energy and nutrient elements in the agroforestry systems are higher.In 8 systems,the comprehensive benefit of a platfoim agroforestry system is the best.
