云杉林碳汇功能评估及影响因素分析
摘 要
云杉林作为我国北方重要的森林生态系统之一,在碳汇功能方面具有显著的潜力。近年来,随着全球气候变化问题的加剧,森林碳汇功能的评估与管理成为学术界和政策制定者关注的焦点。本研究旨在通过多源数据融合与模型模拟,系统评估云杉林的碳汇能力,并探讨影响其碳汇功能的关键因素。研究基于遥感数据、气象观测和实地调查数据,采用多元回归分析、随机森林模型和碳循环模型等方法,对云杉林的碳储量、碳通量及其动态变化进行了定量分析。结果表明,云杉林的年均碳吸收量约为2.3吨/公顷,且在不同气候条件和土壤类型下表现出显著的差异性。其中,温度和降水是影响云杉林碳汇功能的主要气候因子,而土壤有机质含量则对碳储量的长期稳定性具有重要影响。

FUNCTIONAL ASSESSMENT AND INFLUENCING FACTOR ANALYSIS OF CARBON SINK IN SPRUCE FOREST
ABSTRACT
As one of the important forest ecosystems in northern China, spruce forest has significant potential in carbon sink function. In recent years, with the intensification of global climate change problems, the assessment and management of forest carbon sink function has become the focus of academia and policy makers. This study aims to systematically evaluate the carbon sink capacity of spruce forest and explore the key factors affecting its carbon sink function through multi-source data fusion and model simulation. Based on remote sensing data, meteorological observation and field survey data, using multiple regression analysis, random forest model, carbon cycle model, and quantitatively analyzed the carbon reserve, carbon flux and dynamic change of spruce forest. The results showed that the average annual carbon uptake of spruce forest was about 2.3 tons / ha, and it showed significant differences under different climatic conditions and soil types. Among them, temperature and precipitation are the main climatic factors affecting the function of carbon sink in spruce forest, while the soil organic matter content has an important influence on the long-term stability of carbon reserves.
