摘 要
本研究旨在对比分析针叶林与阔叶林土壤碳储量的差异。通过采集两种林型下不同深度的土壤样品，运用专业的土壤碳测定方法，对土壤有机碳含量进行了精确测量。研究结果显示，针叶林土壤碳储量普遍高于阔叶林，这可能与针叶林凋落物的分解速率较慢、有机质积累较多有关。此外，土壤深度对碳储量也有显著影响，随着土壤深度的增加，碳储量逐渐减少。本研究还进一步探讨了土壤类型、气候条件及植被特征对土壤碳储量的影响，揭示了针叶林和阔叶林在碳循环中的不同作用。本研究不仅为深入理解不同林型对土壤碳储量的影响提供了科学依据，也为森林碳循环和全球气候变化研究提供了新的视角。通过对比分析，我们发现针叶林在碳储存方面表现出更高的潜力，这对于森林管理和碳汇功能的提升具有重要意义。同时，本研究也为森林生态系统的可持续发展和碳平衡维持提供了理论支持。

Abstract
The purpose of this study was to compare and analyze the difference of soil carbon storage between coniferous forest and broad-leaved forest. By collecting soil samples at different depths under two forest types and using professional soil carbon measurement methods, the soil organic carbon content was accurately measured. The results showed that the soil carbon storage of coniferous forest was generally higher than that of broad-leaved forest, which may be related to the slower decomposition rate of litters and the higher accumulation of organic matter in coniferous forest. In addition, soil depth also has a significant effect on carbon storage, and carbon storage gradually decreases with the increase of soil depth. The effects of soil types, climatic conditions and vegetation characteristics on soil carbon storage were further discussed, and the different roles of coniferous forest and broad-leaved forest in the carbon cycle were revealed. This study not only provides a scientific basis for further understanding of the effects of different forest types on soil carbon storage, but also provides a new perspective for the study of forest carbon cycle and global climate change. Through comparative analysis, we found that coniferous forests showed higher carbon storage potential, which is of great significance for forest management and carbon sink function enhancement. At the same time, this study also provides theoretical support for the sustainable development of forest ecosystem and the maintenance of carbon balance.
Key words: Soil carbon storage; Contrast between coniferous forest and broad-leaved forest; Soil depth; Carbon cycle
