Abstract: In order to reveal the effects of chilling injury on rubber gross primary productivity, the influence of the southern low temperature event in 2008 was taken for example. The rubber chilling injury indexes were analyzed based on the criterion of QX/T169-2012. The rubber chilling injury indexes and the changes of rubber gross primary productivity (GPP) were analyzed to reveal the rubber to the chilling injury incident. The results showed that the rubber gross primary productivity would reduce when faced in chilling injury events. The rubber chilling injury index and the change of the GPP were related each other. But in different area ,at the equally chilling injury index, the rubber GPP decreased degree were different, the main reason was the differences of rubber chilling stress resistance. The rubber chilling injury index and the change of the rubber GPP can be used for assessing the rubber chilling injury damage in the same area.
