- 为促进喀斯特生态脆弱地区植被的种植和生态修复，以贵州省扎佐林场柳杉针叶林、枫香阔叶林和二者组成的针阔混交林为研究对象，分析西南喀斯特地区不同森林类型之间土壤有机碳组分含量、储量及有机碳稳定性的变化特征，并探究土壤理化性质与有机碳组分含量和有机碳稳定性的关系。结果表明，阔叶林土壤有机碳组分易氧化有机碳（F1）和惰性有机碳（F2）含量分别为12.82和10.20 g·kg-1，储量分别为2.68和2.13 kg·m-2，阔叶林F1和F2含量及储量均显著高于针叶林和针阔混交林。针阔混交林F1分配比例为58.73%，显著高于针叶林；针叶林和阔叶林的F2分配比例分别为41.11%和42.82%，显著高于针阔混交林。针叶林（48.55%）和阔叶林（46.21%）有机碳稳定性均显著高于针阔混交林（40.80%）。土壤有机碳组分含量和有机碳稳定性与土壤理化性质（pH、EC、TN、NN、含水量、砂粒质量分数、粉粒质量分数、黏粒质量分数、BD、AN、TP、TN）存在显著的相关性。
- Abstract:
- In order to promote ecological restoration in the ecologically fragile Karst Area, this study focused on conifer forest composed of Cryptomeria japonica var. sinensis Miquel, broadleaf forest composed of Liquidambar formosana Hance, and mixed coniferous and broad-leaved forest at Zhazuo Forest Farm in Guizhou Province. It analyzed the variation characteristics of soil organic carbon content, storage and organic carbon stability among different forest types in southwest Karst Area. The study further explored the relationship between soil physicochemical properties and organic carbon content and organic carbon stability. The results showed as follows, the contents of readily oxidizable carbon (F1) and recalcitrant organic carbon(F2) of soil organic carbon in broad-leaved forest were 12.82 and 10.20 g·kg-1, respectively, and the reserves were 2.68 and 2.13 kg·m-2, respectively. The contents and reserves of F1 and F2 in broad-leaved forest were significantly higher than those in coniferous forest and mixed forest. The F1 distribution ratio of mixed forest was 58.73%, which was significantly higher than that of coniferous forest. The F2 allocation ratio of coniferous forest and broadleaved forest was 41.11% and 42.82%, respectively, which was significantly higher than that of mixed forest. The organic carbon stability of coniferous forest (48.55%) and broad-leaved forest (46.21%) was significantly higher than that of mixed forest (40.80%). Soil organic carbon component content and organic carbon stability were significantly correlated with soil physical and chemical properties (pH, EC, TN, NN, water content, sand mass fraction, silt mass fraction, clay mass fraction, BD, AN, TP, TN).
