摘　　要：W5 eucalyptus clones short-rotation industrial raw material forest ownered by Leizhou Forestry Bureau were selected to be the object of site quality evaluation,the relations among tree height,DBH,and age were analysed by forest resources survey data.The average height and average DBH of dominant tree in forest stand were selected to be dependent variable and independent variable of site quality evaluation model.The standard age was 3.2 years(40 months),and the curve function was Richard function.The site quality evaluation model of eucalyptus short-rotation industrial raw material forest was established.The adaptability of the model was tested,correlation coefficient was 0.95,and the result showed that the difference between theoretical value and investigating value was not obvious.The accuracy of site quality evaluation model was high enough for practical purposes.W5 eucalyptus clones short-rotation industrial raw material forest ownered by Leizhou Forestry Bureau were selected to be the object of site quality evaluation, the relations among tree height, DBH, and age were analysed by forest resources survey data. The average height and average DBH of dominant tree in forest stand were selected to be dependent variable and independent variable of site quality evaluation model. The standard age was 3.2 years （40 months）, and the curve function was Richard function. The site quality evaluation model of eucalyptus short-rotation industrial raw material forest was established. The adaptability of the model was tested, correlation coefficient was 0.95, and the result showed that the difference between theoretical value and investigating value was not obvious. The accuracy of site quality evaluation model was high enough for practical purposes.
