Abstract

The effects of environmental factors on the site indexes of Sugi (Cryptomeria japonica) and Hinoki (Chamaecyparis obtusa) manmade coniferous forest stands were analyzed in the Shikoku National Forest using GIS. Rock type had a significant relationship with the site index, while soil type did not. Temperature had a positive relationship and radiation had a negative relationship with the site index data of Sugi and Hinoki. On the other hand, precipitation had a positive relationship with the site index of Sugi, but no significant relationship with the site index of Hinoki. Snow depth had a negative relationship with the site index of Hinoki, while it had no significant relationship with the site index Sugi. These results correspond well with the species' characteristics.
