W5 eucalyp tus clones short2rotation industrial raw material forest ownered byLeizhou ForestryBureau wereselected to be the object of site quality evaluation, the relations among tree height, DBH, and age were analysed byforest resources survey data. The average height and average DBH of dominant tree in forest stand were selected to bedependent variable and independent variable of site quality evaluation model. The standard age was 3. 2 years (40months) , and the curve function was Richard function. The site quality evaluation model of eucalyp tus short-rotationindustrial raw material forest was established. The adap tability of the model was tested, correlation coefficient was0. 95, and the result showed that the difference between theoretical value and investigating value was not obvious. Theaccuracy of site quality evaluation modelwas high enough for p ractical purposes.
