TO CALCULATE CHINA''S PLANT-CLIMATE PRODUCTIVE POTENTIALITIES BY "CHIKUZO MODEL
用筑后模型估算我国植物气候生产力

The "Chikuzo Mathematical Model", namely NPP = 0.29 exp(-0.216RDI2)] Rn, has been adopted by a Japanese agricultural meteorologist, Mr. Uchijima, for calculating the plant-climate productive potentiality. In this paper we use this model to calculate the distribution of China's plant-climate productive potentialities and compare the results with those calculated with the Miami and Thornthwaite Mathematical Model.
