摘要
本文对不同类型农林复合生态系统生产力进行调查测定与分析，结果表明：农林复合生态系统生产力大小随树种、林龄、作物种类及配置形式的不同而有差别。果农短期复合型生产力、光能利用率低于果农长期复合型，农杨复合型生产力、光能利用率高于农桐复合型。
The investigation, observation and analysis on productivity of different types of agroforestry ecosystems show that the productivity differed with tree species, age of stand, variety and pattern of crops. The productivity and use percent of solar energy in the short term fruit tree crop intercropping were lower than those in the long one; these in the poplar-crop intercropping were better than those in the paulownia-crop intercropping; these in the apple-hot pepper intercropping were higher than those in the hot pepper-chinese prickly intercropping.
