【 摘 要 】

The stem sap flow characteristics of mixed forest of Maple camphor mixed forest in mountain area of West Hunan Province were studied. The results showed that during the observation period, the rainfall in the study area was 1971.84 mm and the number of rainfalls was 83 times. The stem flow of the mixed forest increased with the increase of rainfall, and there was a significant linear relationship between the stem flow and rainfall. The fitting equation of Maple camphor mixed forest was y = 0.0218x-0.0356, R2 = 0.6376.
