Abstract:
This paper put forward that the indexes for the site quality assess should be decided in the light of the favored tree species and cultural aims reasonally in the construction of commercial forest base with a example from that of paper-making
Dendrocalumus forest base. The factors of site were preliminarily chosen quantitatively, according to the biological characteristics of tree species and the difficulty degree of site quality measurement combined with the forest production. The approach of "Fuzzy Clustering for the sites"was adopted to assess the site quality of afforesting land base concerned, this was of living guide significance for afforestation base construction.
