【摘要】 <正> 为了进一步阐明植被保持水土的作用,我们对黄土高原不同植被类型的地上部分和枯枝落叶层的截留降水作用,以及不同植被类型减少迳流和土壤冲刷的作用做了一些观测,其结果如下。由于篇幅的限制,试验布设和观测方法在此不作详细介绍,感兴趣的同志请查阅试验报告。更多还原

【Abstract】 Observations were made by the authors at several spots on the loess plateau, to investigate the effect of different vegetative covers in intercepting rains, reducing runoffs and soil erosion, from which appropriate data have been acquired not only qualitatively displaying the role of vegetative cover in preventing soil erosion, but also giving the amount of rainfall intercepted and reduction of soil erosion by different types of vegetative covers.更多还原
