基于FORECAST模型模拟杉楠混交林的固碳量
|
摘要
研究不同混交比例对杉阔混交林固碳的影响,对增加人工林生物多样性、优化林分结构、提升固碳潜力具有重要意义。应用FORECAST模型模拟了不同混交比例对杉楠混交林固碳的长期影响,达到优化经营杉木人工林的目标。研究表明,在中等立地条件下,杉木和楠木混交时楠木比例不宜过大,杉木和楠木以3:1的混交比例最适宜,是混交林中固碳效果最优的。在增加土壤有机碳方面,楠木纯林>杉楠混交林>杉木纯林,这是因为楠木土壤有机质含量丰富,土壤结构较杉楠混交林和杉木纯林疏松。
To study the effects of different mixed ratios on carbon sequestration in Chinese fir and broad-leaved mixed forests is an great significance for increasing the biodiversity of plantation forests, optimizing the stand structure and enhancing the carbon sequestration potential. The FORECAST model was used to simulate the long-term effects of different mixed ratios on carbon sequestration of Chinese fir and its mixed forests, and the goal of optimizing the management of Chinese fir plantations were achieved. The research shows that under the condition of medium site conditions, the proportion of Phoebe bournei in the mixed forests should not be too large, and the mixed ratio of Chinese fir and Phoebe bournei with 3:1 is the most suitable, which is the best carbon fixation effect in mixed forests. In terms of increasing soil organic carbon, Phoebe bournei>mixed forests > Chinese fir, this is because the soil organic matter content of Phoebe bournei is rich, and the soil structure is looser than the mixed forests and Chinese fir.
