Moso bamboo (Phyllostachys pubescens) is widely used for afforestation and reforestation in subtropical China because of its high carbon (C) sequestration rate and ability to control soil erosion in degraded areas; it also plays an important role in mitigating climate change. To satisfy the requirements of carbon trading systems, methodologies for estimating changes in C storage under different planting approaches and site conditions are needed. A 10-year field monitoring study of a moso bamboo reforestation area was carried out to research the effects of different planting approaches and site conditions on stand structure dynamics and aboveground C storage accumulation (AGCSA). The bamboo was transplanted in groups of 3 plants (3-PG) or as individual plants (IP). The site conditions were classified into three categories (poor, fair and excellent). The bamboo diameter at breast height (DBH) and height exhibited a slow-fast-slow growth rate trend under both planting approaches. The DBH and height peaked in the 9th year under the 3-PG approach, but maximum DBH and height values were not reached under the IP approach during the study period. The density (D) of new culms (NCs) peaked at five years after reforestation under both planting approaches, and the aboveground C storage (AGCS) of NCs peaked seven years after reforestation. Both planting approaches exhibited clear on-year and off-year plant growth characteristics. The different planting approaches and site conditions significantly influenced AGCSA. Growth models for DBH, height and AGCSA under the specific silvicultural approaches and site conditions were established on the basis of the identified correlations. Ten years after reforestation under the 3-PG approach, the AGCSA was only 3.71 Mg C ha⁻¹ under poor site conditions, while under excellent site conditions, the AGCSA reached 14.71 Mg C ha⁻¹. An optimized management model that considers soil factors has great potential for improving C sequestration in moso bamboo forests.

毛竹（Phyllostachys pubescens）因其高的碳（C）固存率和控制退化地区土壤侵蚀的能力而在亚热带地区被广泛用于造林和再造林。它在缓解气候变化方面也起着重要作用。为了满足碳交易系统的要求，需要估算在不同种植方式和场地条件下碳储存量变化的方法。进行了为期10年的毛竹造林地区野外监测研究，以研究不同种植方式和场地条件对林分结构动态和地上碳储量积累（AGCSA）的影响。将竹子移植为3种植物（3-PG）或单独种植（IP）。工地条件分为三类（差，中，优）。在两种种植方式下，胸径和胸高的竹径均表现出缓慢-快速-缓慢生长的趋势。在3-PG方法下，DBH和身高在第9年达到峰值，但在研究期间，在IP方法下，未达到最大DBH和身高值。在两种种植方式下，新造林（NC）的密度（D）在造林后的五年达到峰值，而在造林后七年，NC的地上碳储量（AGCS）达到峰值。两种种植方法均显示出清晰的年度和年度植物生长特征。不同的种植方式和场地条件对AGCSA有显着影响。在确定的相关性的基础上，建立了在特定造林方法和场地条件下DBH，高度和AGCSA的生长模型。^-1在恶劣的现场条件下，而在良好的现场条件下，AGCSA达到14.71 Mg C ha ^-1。考虑土壤因素的优化管理模型具有改善毛竹林中固碳的巨大潜力。
