不同林分类型土壤碳储量及其影响因素分析
摘 要
本研究旨在探讨不同林分类型对土壤碳储量的影响及其相关因素。通过采集多种林分类型的土壤样本，运用化学分析和统计学方法，对土壤有机碳含量、碳储量及其与土壤理化性质的关系进行了深入分析。结果表明，不同林分类型间土壤碳储量存在显著差异，其中针叶林土壤碳储量高于阔叶林。土壤碳储量与土壤质地、水分含量及微生物活性等因素密切相关。本研究创新性地揭示了林分类型对土壤碳储量的影响机制，为森林生态系统碳循环研究提供了新的视角。同时，研究成果对于指导林业生产实践、提升土壤碳汇功能具有重要意义，为应对全球气候变化提供了科学依据。

Abstract
This study aimed to investigate the influence of different stand types on soil carbon reserves and its associated factors. By collecting soil samples of various forest types and using chemical analysis and statistics, the soil organic carbon content, soil carbon reserves and their relationship with soil physical and chemical properties were deeply analyzed. The results showed that soil carbon reserves were significantly different among different stand types, with higher soil carbon reserves in coniferous forests than in broad-leaved forests. Soil carbon reserves are closely related to soil texture, moisture content and microbial activity. This study innovatively revealed the influence mechanism of stand type on soil carbon reserves, and provided a new perspective for the study of carbon cycle in forest ecosystems. At the same time, the research results are of great significance for guiding forestry production practice and improving the function of soil carbon sink, and provide a scientific basis for coping with global climate change.
