| 摘 要： | 本研究量化了美国俄亥俄州橡树-山毛榉混交林森林碳储量，研究结果表明森林碳密度的增长率与其商品材积和总材积的增长率是一致的。橡树-山毛榉混交林连年增长量（CAI）和年平均增长量（MAI）高峰值分别出现在第23和46年。对于地上碳储量而言，其CAI和MAI最高值分别出现在第26年和53年。对于地上碳密度和地上商品材碳密度，其MAI高峰出现在第30年，与其同时间内总蓄积量和商品材的蓄积量出现的情况一致。了解了森林碳储量的增长和蓄积量的增加模式是相近的道理，有助于我们理解森林蓄积量增长的管理模式过渡到森林碳储量管理的模式。

| Abstract: | Carbon （C） stocks and sequestration rates were determined for oak-hickory forests in Ohio, USA. The models we developed show that the patterns of C sequestration rates follow what we expect in total and merchantable volume increment. The current annual increment （CAI） and the mean annual increment （MAI） peaks at ages 23 and 46 years, respectively, for total aboveground C. The peak CAI and MAI for the aboveground C peaks at ages 26 and 53 years, respectively. The 5-year periodic MAI for both total aboveground C and aboveground portion of merchantable trees occurs at age 30 years, occurring simultaneously with the 5-year periodic MAI for total and merchantable volume. Knowing that C sequestration occurs in similar patterns to volume growth is helpful in transitioning from traditional volume-based management to carbon-based management. |
