摘　　要：以陕西省淳化县西坡村农果复合系统为例,对比分析了2008和2010年农业、果业、畜牧业、人类子系统的能流路径、能流投入、产出结构和能量循环指数.结果表明:2008—2010年间,研究区农果复合系统总投入下降了1.6%,总产出却增长了56.7%,产投比增加了59.4%.各子系统(农业子系统、果业子系统、畜牧业子系统和人类子系统)的能量产投比分别增长了36.6%、21.0%、10.0%和3.8%;西坡村仍需坚持"稳定农业、发展畜牧业和强化果业"的发展方针,以促进农果复合系统的发展和优化升级.Taking the crop-fruit farming system in Xipo Village in Chunhua, Shaanxi Province as a case, the energy flow path, input and output structure, and the indices of energy cycle for the agri- culture, fruit, stockbreeding and human subsystems were compared between 2008 and 2010. Re- sults showed that during the study period the total investment to the agricuhure-fruit farming system （CAF） decreased by 1.6%, while the total output increased by 56.7%, which led to a 59.4% in- crease of the output/input ratio. Energy output/input ratio of the agriculture, fruit, stockbreeding, human subsystems increased by 36.6% , 21.0%, 10.0% and 3.8%, respectively. The Xipo Vil- lage still needed to stabilize the agriculture, develop stockbreeding and strengthen fruit to upgrade the compound agriculture-fruit farming system.
