造林方法是树木生长和林分结构的重要决定因素。然而，长期森林管理的潜在优势，即，混合有价值的非固氮阔叶树种，如红锥，马尾松Pinus massonianaLamb.增加林分生长和生态系统碳储存，仍然知之甚少。本研究对26年生红锥（100C26）、26年生马尾松（100P26）、50年生马尾松（100P50）、均匀和非均匀年龄（50C26+ 50P26和50C26 +50P50）混交林的树木生长、地上部碳积累和地下部碳固定进行了研究。50C26 + 50P50混交林生态系统总碳储量、乔木层和土壤层碳储量均显著高于100C26和100P50单作林的平均值（p< 0.05）。相比之下，灌木层和枯落物层之间的差异不显著，整个生态系统中观测到的碳储量值与预期值之间的差异也不显著，但50C26 + 50P26混合种植园土壤中的碳储量除外。这些结果表明，马尾松与红蜘蛛异龄混交林通过正交互作用促进了碳汇。
Silvicultural practices are an important determinant of tree growth and stand structure. However, the potential advantages of long-term forest management, i.e., mixing valuable non-N2-fixing broadleaf tree species, such asCastanopsis hystrixMiq., with Masson pine (Pinus massonianaLamb.) to increase stand growth and ecosystem carbon storage, remain poorly understood. In this study, we assessed tree growth, aboveground carbon accumulation, and belowground carbon sequestration in 26-year-old monocultures ofC.hystrix(100C26), 26-year-old monocultures ofP.massoniana(100P26), 50-year-old monocultures ofP.massoniana(100P50), and even- and uneven-aged (50C26+50P26and50C26+50P50, respectively) mixed plantations. Carbon storage within the total ecosystem and in the tree and soil layers of50C26+50P50mixed plantations was significantly greater than values predicted based on the means of the100C26and100P50monoculture plantations (p< 0.05). By contrast, differences within the shrub and litter layers were not significant, nor were the differences between observed and expected carbon storage values in the total ecosystem, except in the case of carbon stock in50C26+50P26mixed plantation soils. These results indicate that plantations of uneven-aged mixtures ofP.massonianaandC.hystrixpromote carbon sequestration via positive interactions.
