亚热带森林碳储量与固碳量的构成及影响因素——以武宁县为例

Shuitu Baochi Xuebao
目的准确评估区域森林碳储量和固碳量的数值、分布特点、构成和影响因素，是科学制定森林管理及相应调控政策的重要依据。方法选择隶属于亚热带典型森林区域的生态型县域作为研究对象，选取97个不同树种及不同龄组的样地开展地上、地下碳储量和固碳量的实测，分析碳储量的构成及其与立地因子的相互关系，并将实测固碳量值与CASA模型计算值比较，以期为亚热带森林碳储量和固碳量评估提供参考。结果1）2020年研究区森林平均碳密度、总碳储量、植被层总固碳量分别为158.05 t/hm²、4.07×107 t、28.41×105 t/
