摘要: 基于云南省第五次、第六次和第七次森林资源连续清查样地数据,以优势树种为云南松的样地为研究对象,采用生物量转换因子法及生物量和碳储量之间的转换模型,分别计算和分析不同海拔梯度、龄组、郁闭度、林分密度以及径级的云南松样地生物量和碳储量及其变化情况。结果表明:1)云南松样地生物量和碳储量随海拔的升高呈先升高后降低的变化趋势,1 800~2 400m为云南松生长的最适宜海拔区间;2)随龄组的增加呈先升高后降低的变化趋势,样地生物量和碳储量最高值出现于中龄林;3)随郁闭度的增大呈先升高后降低的变化趋势,最高值出现于中郁闭度林分;4)随林分密度的增加呈先升高后降低的变化趋势,最高值出现于Ⅱ林分密度级;5)随径级的增大呈先升高后降低的变化趋势,最大值出现于中径组。

Abstract: Based on the data of the Continuous Forest Inventories(CFI),Biomass Expansion Factor(BEF) and the conversion model between biomass and carbon storage were used to estimate and analyze the biomass and carbon storage of different altitudes,age classes,canopy density,stand density and diameter classes and their variations.The results show that:1) the biomass and carbon storage of Pinus yunnanensis showed increase at first and then decrease with the increase of altitude.The 1800-2400 meters was the most suitable altitude range for Pinus yunnanensis growth.2) with the increase of age classes,it showed increase at first and then decrease.The highest value of sample biomass and carbon storage appeared in the middle-age forest.3) it showed increase at first and then decrease with the increasing of canopy density,the highest value appeared in the middle canopy density.4) with the increase of stand density,it showed increase at first and then decrease.The highest value appeared in Ⅱ stand density.5) with the increase of the diameter,it showed increase at first and then decrease.The maximum value appeared in the middle-diameter group.
