【摘要】：森林土壤有机碳在全球碳循环与收支中占主导地位,探究多因子交互作用对土壤有机碳密度的影响,对精确评估土壤有机碳储量、科学预测气候变化以及制定应对气候变化的策略具有重要意义。研究依托国家森林资源清查样地,在江西省选择典型样地进行样地调查和土壤样品采集,运用数量化理论Ⅰ,探讨多因子对土壤有机碳密度的影响,结果表明:林分类型、龄组、海拔、坡向、坡位、土壤类型6个因子是影响土壤有机碳密度的主导因子;并运用数量化理论Ⅰ,构建了林分类型、龄组、海拔、坡向、坡位、土壤类型6个主导因子与森林土壤有机碳密度之间的估算模型。
[Abstract]:Forest soil organic carbon plays a dominant role in the global carbon cycle and budget. It is of great significance to predict climate change scientifically and to formulate strategies to deal with it. Based on the national forest resource inventory and sample plots, the typical sample plots were selected to investigate and collect soil samples in Jiangxi Province. The effects of multiple factors on soil organic carbon density were studied by quantitative theory 鈪，
