《京都议定书》第3.4条强调了延长森林管理轮伐期，以帮助各国履行减少温室气体排放的承诺。利用CO2 FIX模型Ver.3.2研究了不同轮作年限下中国西南地区橡胶种植园碳储量的动态变化。为了估计作为第三条第4款活动增加轮伐期的效率，研究预测，随着轮伐期的增加（25年、30年、35年、40年和45年），生态系统的橡胶产量和碳储量增加。在比较各轮伐期的经济（橡胶产量）和生态（碳储量）增长速度时，40年轮伐期的产量和碳储量均达到最大值。经过40年的轮伐期延长为连续4个周期后，得出该生态系统的总碳储量为186.65 Mg ha-1。较长的轮伐期在连续4轮伐期后，地下C种群中C种群相对增加。橡胶园碳输入（Mg C ha-1 yr-1）和橡胶产量的变化趋势表明，橡胶种植园以40年轮作为宜。该研究基于四种轮换情景制定了碳减排措施。连续长轮伐期后整个生态系统碳储量可能增加，这表明西南地区橡胶种植园的轮伐期应作为《京都议定书》第3.4条报告的重点。
Extension of the rotation length in forest management has been highlighted in Article 3.4 of the Kyoto Protocol to help the countries in their commitments for reduction in greenhouse gas emissions. CO2FIX Model Ver.3.2 was used to examine the dynamics of carbon stocks (C stocks) in a rubber plantation in South Western China with the changing rotation lengths. To estimate the efficiency of increasing the rotation length as an Article 3.4 activity, study predicted that the rubber production and C stocks of the ecosystem increased with the increasing rotation (25, 30, 35, 40 and 45 years). While comparing the pace of growth both in economical (rubber production) and ecological (C stocks) terms in each rotation, 40 years rotation length showed maximum production and C stocks. After elongation of 40 year rotation to four consecutive cycles, it was concluded that the total C stocks of the ecosystem were 186.65 Mg ha-1. The longer rotation lengths showed comparatively increased C stocks in below ground C stock after consecutive four rotations. The pace of C input (Mg C ha-1yr-1) and rubber production indicated that 40years rotation is best suited for rubber plantation. The study has developed carbon mitigation based on four rotation scenarios. The possible stimulated increase in C stocks of the entire ecosystem after consecutive long rotations indicated that the emphasis must be paid on deciding the rotation of rubber plantation in SW China for reporting under article 3.4 of the Kyoto Protocol.
