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。
This study quantified forest carbon stocks in the oak-beech mixed forest in Ohio, USA. The results show that the forest carbon density increases at a rate consistent with the increase in both the commodity and aggregate volumes. The peak values of annual tree growth (CAI) and annual average growth (MAI) of oak-beech mixed forest appeared in the 23rd and 46th years respectively. For above-ground carbon stocks, the highest values of CAI and MAI occurred in the 26th and 53th years, respectively. For the above-ground carbon density and aboveground carbon density, the MAI peak appeared in the 30th year, consistent with the occurrence of total stock volume and commodity stock volume in the same period. Understanding the pattern of increases in forest carbon stocks and increasing stock volume is a similar principle that helps us to understand the mode of management of forest stock volume growth to the mode of forest carbon stock management.
