- 摘要:
- 在全球气候变化背景下，人工林的适应性管理对固碳潜力的提升具有重要影响。应用加拿大不列颠哥伦比亚大学开发的FORECAST森林生态系统管理模型，通过外业调查、查找相关文献资源等方式收集不同立地条件下杉木林分的生物量积累、林分密度、光响应曲线及土壤养分方面的数据。模型经过校准和检验后，模拟不同采伐剩余物处理方式对杉木人工林固碳量的影响。结果表明：SO处理（采伐茎干，采伐剩余物留在林地）对杉木林长期固碳效果最好；FR处理其次（采伐茎干，清除地上部分采伐剩余物），而WH（全树采伐，清除所有采伐剩余物）和SB（采伐后，火烧采伐剩余物）固碳效果最差。该研究可为杉木人工林的可持续经营提供理论依据。
- Abstract:
- Under the background of global climate change, adaptive management of plantation has the important influence on the promotion of carbon sequestration potential. Using FORECAST ecosystem management model developed by University of British Columbia, Canada, through field investigation, collecting Chinese fir relevant literature resources under different site conditions. The data include biomass accumulation, stand density, light response curve and soil nutrient, we calibrate and test model, and simulate different logging residue treatment effects of Chinese fir plantation on carbon sequestration. The results showed that SO treatment (cutting stem, logging residue in forest land) of Chinese fir carbon sequestration long-term effect is the best, followed by FR treatment second part (cutting stem, cleaning the ground logging residue), but WH (cutting full tree, remove all logging residue) and SB (after cutting, burning logging residue) carbon sequestration effects are the worst. This study can provide theoretical basis for sustainable management of Chinese fir plantation.
