摘　　要：当前森林土壤有机碳的研究随着全球气候变化的日益加剧越来越受到重视。由于地理位置独特,生态系统较为复杂,藏东南地区成为研究森林土壤有机碳汇的重要区域。文章对近年来藏东南森林土壤有机碳储量和密度的海拔格局及其对气候变化响应的相关研究进行了分析。分析表明,受气温、降水、植被类型等因素的综合影响,藏东南森林土壤有机碳储量和密度在海拔梯度上呈现出明显的空间异质性。此外,气候变化还对藏东南地区森林土壤有机碳的贮存与释放造成了一定程度的影响。探究藏东南森林土壤有机碳汇海拔格局与相关气候因子之间的关系,有助于了解土壤有机碳对气候变化的响应机制,以期为生态恢复和气候适应提供理论支持。At present,the study of forest soil organic carbon has been paid more and more attention with the increasing global climate change.Due to its unique geographical location and complex ecosystems,southeast Xizang has become an important region for studying forest soil organic carbon sinks.This paper summarizes the studies on the elevation pattern of forest soil organic carbon storage and density and its response to climate change in recent years.It was found that forest soil organic carbon storage and density in southeast Xizang showed obvious spatial heterogeneity on the altitude gradient under the comprehensive influence of temperature,precipitation,vegetation type and other factors.In addition,climate change also has a certain degree of impact on the storage and release of forest soil organic carbon in southeast Xizang.To explore the relationship between the elevation pattern of soil organic carbon sink and related climate factors in southeast Xizang,it is helpful to understand the response mechanism of soil organic carbon to climate change,with a view to providing theoretical support for ecological restoration and climate adaptation.
