Abstract:
The potential productivity was studied by Lieth,Miami and Thomthwaite model.The potential productivity depended on the climate.Based on the Logistic accumulating distribution model,the actual maximum potential productivity of the planting Eucalyptus stand was studied.The ways for getting maximum productivity value,the optimal period of productivity were discussed.Results show that:Short rotation Eucalyptus plantation stands cultivated in site type Ⅰ have reached better productivity level,the present managerial condition,and the difference between the actual growing stock and the maximum potential are no more than 15%.The best time for productivity is in about 3 years after being planted.
