Abstract
In the paper discussions were made on the monitoring and assessment of rainfall, run-off, and sediment concentration produced in three cultivation models of Cinnnamomum petrophilum plantation. Through two years' observation, we come to two results: i) the amount of run-off decreases when the figures of 2-year stands are compared with those of 3-year stands after plantation, and ii) the amount of run-off also decreases along with different models. For example, the model of pure C. petrophlium stands shows a decrease by 91.81 percent, and the model of C. petrophlium + Trifolium repens mixed stand shows a decrease by (88.97) percent. The pure C. petrophlium stand model and C. petrophlium + Trifolium repens mixed stand model have a lower run-off than the agricultural crop model. At the stand age of 2, the amount of run-off is lowered by 35.3 percent and by 34 percent in the pure C. petrophlium stand and C. petrophlium + Trifolium repens mixed stands.
