摘要：Moso bamboo and natural secondary forests are the typical forest types in subtropical area in China. With field observation at the Qiangjiangyuan Forest Ecosystem Research Station. the effect of the two typical forests was compared on soil and water conservation and their difference was quantified. The results showed that: (1) The runoff coefficients for moso bamboo and natural broad-leaved secondary forest go up with increase of precipitation. (2) Natural broad-leaved secondary and moso bamboo forests both are pretty good in preservation of water source and water and soil conservation. The former is better than the latter. moso bamboo forest is over 90% higher than natural broadleaved secondary in runoff generation, and three times higher in sediment yield. (3) Runoff for two forest types has a significant correlation with precipitation outside the forest. Total runoff has a significant linear relation with precipitation, and the runoff coefficient has a logarithm correlation with precipitation.
