In order to explore the redistribution processes of rainfall that were caused by canopy

five typical forest types in the upper reaches of the Hun River

including Korean pine plantation (KP)

larch plantation (LP)

broadleaf-Korean pine mixed forests (BKMF)

broadleaf-larch mixed forests (BLMF) and broadleaved mixed forests (BMF) were studied. Throughfall

stemflow and canopy interception were recorded by automatic data recorder. The results showed that the throughfall

stemflow

and canopy interception in five typical forests increased linearly with an increase of rainfall. The rate of throughfall and stemflow logarithmically increased as rainfall increased. The stemflow in BKMF (32.12%) and BLMF (15.44%) was higher than those in KP

LP

and BMF. The canopy interceptions in KP (80.66%) and LP (77.47%) were higher than those in the other three forest types. This study provides the theoretical basis for the configuration of water conservation forest with the optimal spatial pattern and management strategies in the upper reaches of the Hun River.
