土壤无机碳（SIC）和有机碳（SOC）水平随森林发育而变化，但土壤碳平衡的同步变化及其在调节土壤性质方面的功能差异尚不清楚。本文通过分析种植园生长过程中SIC和SOC储量的同步变化及其在维持土壤可持续性方面的功能差异，对49个落叶松种植园林时序样地土壤SIC、SOC等理化性质（N、碱解N、有效Si、电导率、pH和容重）进行了评价。这些土壤具有高SOC（15.34 kg m−2）和低SIC储量（平均83.38 g m−2）的特征。此外，SIC和SOC存储和落叶松生长参数（年龄，树木大小和生物量密度）之间的30个线性回归中有28个没有统计学意义（p 0.05）。然而，观察到SIC和SOC比值随这些生长参数发生显著变化（分别在0-40 cm和40-80 cm之间; p 0.05）。这些结果更有助于确定SIC和SOC垂直分布的变化比存储的变化。线性相关和多元回归分析表明，土壤有机碳影响土壤氮素，土壤有机碳影响土壤酸度。这清楚地表明，落叶松的生长可能会导致不同的SIC和SOC水平的变化，特别是在他们的垂直分布;此外，SIC和SOC的变化可能会间接影响土壤理化性质。
Soil inorganic carbon (SIC) and organic carbon (SOC) levels can change with forest development, however, concurrent changes in soil carbon balance and their functional differences in regulating soil properties are unclear. Here, SIC, SOC, and other physicochemical properties of soil (N, alkali-hydrolyzed N, effective Si, electrical conductivity, pH, and bulk density) in 49 chronosequence plots of larch plantation forests were evaluated, by analyzing the concurrent changes in SIC and SOC storage during growth of plantation and the functional difference of these levels in maintaining soil sustainability. These soils had characteristically high SOC (15.34 kg m−2) and low SIC storage (83.38 g m−2 on average). Further, 28 of 30 linear regressions between SIC and SOC storage and larch growth parameters (age, tree size, and biomass density) were not statistically significant (p > 0.05). However, significant changes were observed in ratios of SIC and SOC with these growth parameters (between 0–40 cm and 40–80 cm, respectively; p < 0.05). These results were more useful for determining the changes in SIC and SOC vertical distribution than changes in storage. Moreover, larch growth generally decreased SIC and increased SOC. Linear correlation and multiple-regression analysis showed that the SIC influences soil acidity, whereas SOC affects soil nitrogen. This clearly indicates that larch growth could result in divergent changes in SIC and SOC levels, particularly in their vertical distribution; further, changes in SIC and SOC may variably affect soil physicochemical properties.
