为明确工程堆积体不同植被类型下土壤有机碳(SOC)及易氧化有机碳(EOC)变化特征及其影响因子
分别设置乔木、灌木、草地和裸地这4种类型样地
分层采集0—10
10—20
20—40
40—60
60—80 cm的土壤并测定其有机碳组分及理化性质
采用主成分分析法及相关性分析法进行分析。结果表明:(1)不同植被类型之间SOC含量存在显著差异
乔木、灌木、草地和裸地下SOC均值依次为45.73
41.81
34.75
21.11 g/kg
植被恢复显著提升SOC含量
且表层土壤提升效果优于深层土壤。(2)乔木和灌木下土壤碳库活度(活性有机碳与非活性有机碳之比)显著高于草地
乔木、灌木下SOC更容易被植物吸收利用。(3)全氮(TN)、全磷(TP)、水解氮(HN)与SOC、EOC均呈显著正相关(p<0.05)
对SOC的提升起主要作用。因此
混种具有固氮作用的豆科植物有利于SOC的提升和积累。
In order to determine the change characteristics and influencing factors of soil organic carbon (SOC) and easily oxidized organic carbon (EOC) under different vegetation types of engineering deposits
four types of sample plot of tree
shrub
grassland and bare land were set up in this study
and the soil samples were collected at the depth of 0—10
10—20
20—40
40—60 and 60—80 cm. The organic carbon components and physical and chemical properties of the soil were determined by principal component analysis and correlation analysis. The results showed that: (1) There were significant differences in SOC content among different vegetation types. The mean values of SOC in tree plot
shrub plot
grassland plot and bare soil were 45.73
41.81
34.75 and 21.11 g/kg
respectively. Vegetation restoration significantly increased SOC content
especially in surface soil. (2) Soil carbon pool activity (ratio of active organic carbon to inactive organic carbon) of tree plot and shrub plot was significantly higher than that if grassland plot
and SOC of tree plot and shrub plot was easier to be absorbed and utilized by plants. (3) Total nitrogen (TN)
total phosphorus (TP) and hydrolysis nitrogen (HN) were significantly positively correlated with SOC and EOC (p<0.05)
and played a major role in the improvement of SOC. Therefore
mixing legumes with nitrogen fixation effect was beneficial to the improvement and accumulation of SOC.
