摘　　要：以生态环境脆弱的黄土高原丘陵沟壑区典型小流域纸坊沟为例,研究它的由植物初级生产力、动物次级生产力、农户经济生产力及生态系统服务生产力组成的农业生态系统生产力各组分的特征及相互间的耦合与相悖关系。采用一些定性和定量的指标初步分析了小流域乃至黄土高原地区的农业发展问题。Using Zhifanggou, a small fragile loess plateau hilly area valley for an example, this study looked at agricultural ecosystem productivity. Primary plant productivity, secondary animal productivity, economic productivity of farmers and ecosystem productivity was looked at, including their characteristics and mutual coupling and opposition. Some qualitative and quantitative indexes were adopted to carry out an initial analysis of agricultural development issues concerning small drainage areas and even of loess plateaus.
