Abstract:
According to field investigation and soil analysis on the littoral region of Dongtai forest station, this paper advances a suitable system and method of site classification and site quality evaluation. On the basis of ground water depth and soil salt content sieved from many restrictive factors, the investigation area may be divided into 7 site groups, then, with the aid of IBM computer, site groups are classified into 11 different site types by soil fertility. For the reason of Robinia pseudoacacia, the dominated forest tree species in this area, the paper establishes quantification site index table of the species and regression equation between average height of dominat trees in the stand and timber stores per hactare. So that, site quality of forest or afforested land as well may be evaluated, the author has worked out the site type table, predicated site productivity and also put forward suitable suggestion for the choice of silvicultural tree and forest management.
