Abstract
A map of site productivity distribution is helpful for sustainable and effective use of forest resources. Combining two techniques, one for estimating local site productivity and the other for applying the estimation technique to large land areas, allows us to make the map. In this study, we presented a method to map site productivity distribution using a score table as the former and a geographic information system (GIS) as the latter. The method has merits as follows: 1) the mapping process is rational and accessible, 2) score tables have been already developed in many regions, 3) many environmental factors in those tables can be mapped using GIS, and 4) many referenced data for mapping are easily available. Therefore, the presented method is practical because of its applicability to many regions.
