为了客观评价陕西不同区域苹果种植的优劣势，运用能值方法对陕北和关中4个县4年间苹果种植生态系统的指标进行了对比分析。结果表明陕北和关中地区苹果种植系统的投入结构和能值指标存在明显差异。陕北地区主要依赖购买能值投人，且以可更新有机能为主。而关中地区几乎全部依赖自然资源能值投入。由于在有限的自然资源上投入了过多的购买能值造成了陕北地区环境压力过大。而关中地区过分依赖自然资源能值投入，应加强购买能值投入，提高系统产出效率。

In order to objectively evaluate the advantages and disadvantages of apple grown in different regions in Shaanxi, this paper used energy value method to comparatively analyze the apple＇s growing ecosystem indicators in four counties in central and northern Shaanxi for four years. The results show that there exist obvious difference in input structure and energy value indicators of apple growing system in the regions of central and northern Shaanxi. Northern Shaanxi relies mainly on purchased energy value inputs, and gives priority to renewable organic energy. The Central Shaanxi is almost entirely dependent on the energy value inputs of natural resources. Because of investing too much purchased energy value on limited natural resources, it creates too much pressure on the environment in North Shaanxi Province. The Central Shaanxi is over-reliance on the energy value inputs of natu- ral resources, so to the purchased energy value investment should be strengthened to improve the output efficiency of the system.
