【 摘 要 】

The study aimed to analyze the effectiveness of pine stands in controlling surface runoff on land with a slope >40%, comparing surface runoff on slope >40% by slopes 40% respectively for 3 replications. The bottom of the plot is installed with 3 pieces of 50 liter capacity storage. Observation of surface runoff is taken every time of rain, as many as 39 times rain. The average surface runoff volume (m3/plot) is obtained by summing the volume collected in 3 reservoirs. The results showed that the average surface runoff on slopes 40%. The results of the difference test were 2 on average with a 95% confidence interval; there was no difference in the average runoff on slopes 40%. Regression analysis results show that canopy cover can control surface runoff.
