Abstract

Evaluation of the tree cutting effect on the environment is crucial for wise use of woods considering environmental and biological conservation. In order to evaluate the tree cutting effects on the heat and water environments, a micrometeorological observation was conducted in a conifer-broadleaf mixed forest in northernmost Japan before and after the tree cutting, and the change was discussed. The tree cutting increased the solar radiation on the ground surface and the soil heat flux during the snow free period. However, the ratio of the soil heat flux to solar radiation was still small even after the tree cutting and most of the values were < 5%. Accordingly, there was little difference in the soil temperature between before and after the cutting. Dense undergrowth of Sasa bamboos control the increase of the radiation on the ground surface and soil temperature in this ecosystem, and this may act as an obstacle to tree regeneration. On the other hand, the ceasing of transpiration by trees suppressed the decrease of soil water after the tree cutting. The change of the soil water may lead to the change of the water balance in this watershed.
