- 摘要:
- 生态交错带是全球变化敏感区，研究生态交错带不同土地利用类型土壤有机碳的变化，可为生态交错带因人类活动引起的土地利用和覆被变化对土壤碳汇功能的影响提供基础数据。该文研究了岷江上流干旱河谷/山地森林交错带具有代表性的高山栎地、灌丛地、灌木林地、花椒地、农耕地以及人工刺槐林地不同土层深度土壤中有机碳和易氧化态碳的含量和分布特征，以及易氧化态碳与有机碳的关系。结果表明：不同土地利用类型的有机碳含量和易氧化态碳含量随土层深度的增加而减少；易氧化态碳与有机碳间呈极显著的相关性；土壤易氧化态碳占有机碳的比例波动为3.57%～12.71%，表现为高山栎地＞农耕地＞灌木林地＞人工刺槐林地＞灌丛地＞花椒地。研究结果说明植被类型是导致岷江上游干旱河谷/山地森林交错带不同土地利用类型土壤中有机碳和易氧化态碳含量差异的重要原因。
- Abstract:
- Ecotone is a sensitive region for global climate change,and study on soil organic carbon under different land use types at ecotone could provide basic data for the effect of carbon sink function for land management concerning land use and land coverage change.This paper analyzed the contents and distribution characteristics of soil organic carbon(SOC) and readily oxidation carbon(ROC) and the relationship between them under six kinds of representative land use types(including Quercus semicarpifolia secondary forest,shrub,shrubbery,Zanthoxylum bungeanum forest,farmland and Robinia pseudoacacia plantation) at arid valley-mountain forest ecotone in the upper reaches of Minjiang River.The results showed that respective content of SOC and ROC decreased with the increase of depth of soil;there is extremely significant correlation between SOC and ROC;the ROC content accounted for 3.57%～12.71% of SOC,which showed Quercus semicarpifolia secondary forest>farmland>shrubbery>Robinia pseudoacacia plantation>shrub>Zanthoxylum bungeanum forest.It can be seen that vegetation types is an important reason for causing the content differences between ROC and SOC under different land use types at ecotone.
