The Forestry Agency of Japan emphasizes the development of sustainable multifaceted functions of forests to meet the nation's diverse needs. The people of Japan greatly expect forests to protect the earth from the greenhouse effect and to provide water resources for them. Thus we investigated these two functions to determine the extent to which they have been clearly analyzed by reviews and articles published in the past in order to determine how goverment should deal wiht such demands. As a result, we concluded that the amounts of carbon absorbed and held in trees and soils of forests and emitted therefrom should be measured with a higher degree of accuracy in part by improving the wide range survey system by managing forest resource data using GIS technology. The results also suggested-that it would be useful to construct a simulation model which expresses the function of cultivating water resources in order to investigate the important forest role of cultivating water resources in all watersheds.
