Rain Fall Partition of the Forest Canopy beside Songhua River

Abstract:

Through field investigation and room experiment, the characteristics of the rainfall partition in the canopy layer of six forest types beside Songhua River were studied. The canopy interception of the rainfall was different in six forest types; from maximum to minimum was Quercus monglica forest, Pinus koraiensis plantation, Tilia mandshurica forest, Fraxinus mandshurica-Larix olgensis forest, Fraxinus mandshurica-Populus davidiana forest and Juglans mandshurica forest. There were significant linear correlation between through fall and precipitation and significant exponential correlation between canopy interception and precipitation in studied forest types; The stem flow ratio to gross rain fall ranged from 0.74% to 16.61% in six forest types, from maximum to minimum was Juglans mandshurica forest, Quercus monglica forest, Pinus koraiensis plantation, Fraxinus mandshurica-Larix olgensis forest, Fraxinus mandshurica-Populus davidiana forest and Tilia mandshurica Forest. In the same precipitation condition, the stem flow ratio to gross rain fall should be affected negatively by canopy size.
