摘要
为准确测算湖南省毛竹碳汇林的固碳能力,促进湖南省毛竹碳汇林业的均衡稳定发展,在湖南省毛竹主产区设置标准样地,并根据胸径、龄阶实测258株毛竹的生物量,用多元回归方法建立毛竹地上部分总生物量及其各器官生物量的一元(以胸径为自变量)、二元(以胸径和龄阶为自变量)模型。通过模型评价与检验,各模型均符合适用精度,具有适宜的预估水平。
In order to accurately estimate carbon sequestration of PhyUostachys pubescens and promote the balanced and stable development of bamboo forest of carbon sink. , the standard plots were set up in the main producing areas of P. pubescens in Hunan Province. The biomass data from 258 sampled trees of P. pubescens was determined for total aboveground biomass and biomass of components, including diameter alone; diameter and age as independent variables. Then the multiple regression method was used to develop one and two variable biomass models with advantages of easy ob- tain of indicators and good fitting precision and estimation level in Hunan Province.
