| Abstract: | According to measured data covering a period of over ten years on net primary productivity in Chinese fir plantation and their corresponding mean annual temperature, warm index, precipitation,humidity index as well as evapotranspira tion in Guangxi, the climatic productivity models are developed by least square method for the plants. These models ale used to calculate distribution of the regional climatic productivity for Chinese fir plantation and to compare the results with those calculated by Miami and Thornthwaite Mathematical Model.Results show that the established NPPT, NPPWI, and NPPV models accord with law of actual change of net primary productivity in Chinese fir plantation and the models'reliability is relatively high.Climatic productivity of Chinese fir plantation decreases from north to south.The authors consider that the Miami and Thornthwaite Model is not suited to calculate climatic productivity of Chinese fir plantation because the results calculated with the Model have a great deviation in contrast to the actual value. Moreover, the curve of this model is not tally with the actual change law of the net primary productivity in Chinese fir Plantation.. |
