虽然CO2施肥对植物生长的影响被反复模拟为目前全球范围内陆地碳汇变化的主要原因，但树木年轮分析对CO2施肥对森林的影响存在争议。利用东北地区常规年轮数据，研究了1950 - 2010年CO2施肥对落叶松生长的影响。在四个站点中，有两个站点表现出显着的剩余增长增强在90%的置信水平后，删除的大小，年龄和气候相关的趋势的树轮指数。此外，我们发现高频CO2波动和剩余生长指数之间的一致性（R从0.26到0.33，p < 0.1），在四个地点的两个共同时期。利用一个地球化学模型定量预测了大气CO2浓度升高对累积剩余生长增强的贡献。在树木年轮数据中发现，14%的剩余增长归因于CO2施肥效应，而气候则负责约86%。
Although CO2 fertilization on plant growth has been repeatedly modeled to be the main reason for the current changes in the terrestrial carbon sink at the global scale, there have been controversial findings on the CO2 fertilization effects on forests from tree-ring analyses. In this study, we employed conventional dendrochronological tree-ring datasets from Northeast China, to detect the effect of CO2 fertilization on Larix gmelinii growth from 1950 to 2010. Among four sites, there were two sites exhibiting a significant residual growth enhancement at a 90% confidence level after removing the size, age and climaterelated trends of tree-ring indices. In addition, we found consistency (R from 0.26 to 0.33, p < 0.1) between the high frequency CO2 fluctuation and residual growth indices at two of the four sites during the common period. A biogeochemical model was used to quantitatively predict the contribution of elevated atmospheric CO2 on accumulated residual growth enhancement. As found in the tree-ring data, 14% of the residual growth was attributed to the CO2 fertilization effect, while climate was responsible for approximately the remainding 86%.
