Abstract:
Taking into account the matched relationship between sunlight, heat and water resources and growing law of masson pine itself, a new comprehensive model with climate factors is established for the productivities of masson pines in various elevations and different side of the mountains. In the model, the variations of the meteorological elements, such as, temperature, precipitation and sunshine, in the mountainous areas are amended. The results show that the optimum height for climatic productivity is agreeable to the optimum growing potential of masson pines.The optimum height for the growth of masson pines is determined in the mountainous areas.
