| Research Abstract |
The writer summarize the importance of interception of a forest cover in a hydrologic balance as follows :
1. Intercepted storm water returns to atomosphere soon after it arryves the earth surface without being used by plants.
2. It seems that interception loss reaches a comparatively large amount in himid regions as well as in dry regions, though the importance of canopy interception loss on a hydrologic cycle increases as a climate becomes drier.
3. Interception loss is a part of hydrologic cycle which can be changed by foresters through forest management.
4. Recent research on the mechanism of evapoation from a forest canopy during storm brought about several important probkems such as what is heat source for vaporization and what atmospheric mechanism exists supply heat to canopy surface.
These have a significant meaning for the study of soil-plant-atmosphee system beyond the simple canopy interception
