- 摘要:
- 为了探究小兴安岭地区针、阔叶林土壤碳汇稳定性差异,对小兴安岭凉水国家级自然保护区内针、阔叶林进行调查并采集0~20 cm表层土壤样品,测定土壤有机碳含量(SOC)、土壤异养呼吸速率(Rs)、温度敏感性(Q10)、湿度敏感性(Hs)及土壤理化性质指标。结果表明,阔叶林土壤有机碳含量较针叶林显著高出31.49%(P<0.05),土壤异养呼吸速率针、阔叶林间差异不显著。针叶林土壤温度敏感性(Q10)比阔叶林显著高出16.82%,但湿度敏感性针、阔叶林间差异不显著。与针叶林相比,阔叶林土壤有机碳含量更高,且阔叶林温度敏感性更低。冗余分析结果表明土壤容重对碳汇稳定性影响最大。
- Abstract:
- In orden to explore the differences in soil carbon stability between coniferous-leaved forests and broad-leaved forests in Xiaoxing′an Mountains. This study investigated and collected 0-20 cm soil samples from coniferous-leaved forests and broad-leaved forests in Liangshui Nature Reserve, Xiaoxing′an Mts., and measured soil organic carbon content (SOC), soil heterotrophic respiration rate (Rs), temperature sensitivity (Q10), humidity sensitivity (Hs), and soil physicochemical properties. The soil organic carbon content in broad-leaved forests was significantly higher than that in coniferous-leaved forests by 31.49% (P<0.05), and there was no significant difference in soil heterotrophic respiration rate between coniferous-leaved forests and broad-leaved forests. The Q10 of soil temperature sensitivity in coniferous-leaved forests was significantly higher than that in broad-leaved forests by 16.82% (P<0.05), but there was no significant difference in humidity sensitivity. Compared with coniferous-leaved forests, broad-leaved forests had higher soil organic carbon content and lower temperature sensitivity. Redundancy analysis indicated that soil bulk density had the greatest impact on carbon capture stability.
