摘要: 为了揭示寒害对橡胶树总初级生产力(Gross primary productivity,GPP)的影响,以2008年1—2月发生的南方地区低温事件为例,参照标准QX/T 169-2012计算橡胶树寒害指数,并通过对相应时间段内的橡胶树寒害指数和橡胶树总初级生产力变化的分析揭示橡胶对寒害事件的响应。结果表明,当面临寒害事件时,橡胶树GPP会出现减小的情况;橡胶树寒害指数和GPP的变化有一定的相关性,但不同区域同等寒害指数条件下对不同区域的橡胶树的GPP减小程度有所不同,主要原因是橡胶树抗寒能力差异引起的;在同一区域,可以利用寒害指数和GPP的变化判断橡胶树的受灾程度。

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.

Key words: rubber, chilling injury, gross primary productivity, meteorological index, effects
