该文总结了从杨树片林发展为“两行一带式”间作型丰产林的原理、造林技术配置结构等，并就该模式的效益进行了分析。结果表明：两行一带式丰产林可提高土地利用率达2.65倍，造林成活率达95％以上，间作农作物产量提高25％左右，是一项符合当地自然社会条件的、具有较高经济效益的混农林业模式之一。
This paper summarizes the principle of developing the “two rows and one belt” intercropping high yield forest from the poplar forest and the afforestation technology allocation structure, and analyzes the benefit of this model. The results showed that the two-row and one-belt high-yield forests could increase the utilization rate of land by 2.65 times, the afforestation survival rate of more than 95% and the intercropping of crop yield by about 25%, which is a natural economy with high economic benefits One of the agroforestry models.
