Abstract

Abstract: The production capacity of rubber trees in natural environment is mainly affected by climate factors besides its biological and soil characteristics. The fluctuation of rubber tree yield is closely related to the change of climate factors. Therefore, it is important to accurately and timely evaluate the influence of climatic conditions on rubber production. Based on the climate data and remote sensing data from the year of 2000 to 2015 in Chinese rubber planting areas, the conversion coefficients between potential productivity of rubber and actual productivity of rubber were established by the net primary productivity model of climatic vegetation model which reflecting potential productivity of rubber and the remote sensing CASA model which reflecting actual productivity of rubber. The potential productivity of rubber model based on climate data was established. The results showed that the potential productivity of rubber model based on climate data not only can objectively and quantitatively evaluate the dynamic change of rubber production capacity based on climatic data, but also can indirectly reflect the difference of the impact of climate factors on rubber production capacity in different regions. It would provide decision-making basis for rubber yield prediction, adaptation strategies and measures to climate change for Chinese rubber planting.

Key words: Rubber, Net Primary Production (NPP), Potential productivity of rubber, Model
