摘要

在济宁高潜水位矿区的充填复垦区内，分析完整复垦周期的土壤碳演变特征。通过从塌陷地（M1）、复垦年限为0，3年的复垦耕地（M2、M3）以及正常耕地（M4）采集土样并检测土壤全碳（TC）、有机碳（SOC）、有机碳密度（SOCD）、有机碳组分（WDOC、POC、MOC、LFOC、HFOC、MBC）及稳定性同位素（δ13C），研究不同复垦周期阶段下土壤碳空间特征的变化情况。研究表明：（1）塌陷地的TC、SOC、SOCD和各有机碳组分含量较低。经过复垦措施期后，SOCD在复垦当年就恢复到正常耕地的水平，TC和SOC含量随着复垦年限不断增加。WDOC、POC、LFOC、MBC等组分恢复速率较快，MOC和HFOC恢复周期较长。（2） TC、SOC、SOCD和各有机碳组分的恢复速率随着土层深度的增加逐渐减缓。（3）复垦土壤的δ13C均值在不同深度间的差异较小，而标准差和变异系数偏大，说明复垦土壤层次不明显且同一层次间土壤来源混乱。从整个复垦周期来看，复垦工作虽具有"碳汇"作用，但会对土壤层次造成破坏。建议进行塌陷地治理时，尽量采用对土层扰动较小的复垦方式，对表土剥离和回填工序进行优化和监督，从而达到更好的恢复效果。

Abstract

The soil carbon evolution was studied under a complete reclamation cycle in the Ji'ning coal mine area with the high groundwater level. The stratified sampling and laboratory anlaysis of the soil were carried out under the different reclamation cycles

including Land subsidence (M1)

reclaimed land for 0 and 3 years (M2

M3) and normal cultivated land (M4)

to study the total carbon (TC)

soil organic carbon (SOC)

soil organic carbon density (SOCD)

organic carbon components (WDOC

POC

MOC

LFOC

HFOC and MBC) and stable isotopes (δ13C). The results showed:(1) The contents of TC

SOC

SOCD and organic carbon components in the subsided area were lower. After the reclamation

the SOCD returned to the level of normal cultivated land in the first year

and the TC and SOC contents were increased with the reclamation period. The recovery rates of components such as WDOC

POC

LFOC and MBC were faster

but the MOC and HFOC recovery periods were longer. (2) The recovery rates of TC

SOC

SOCD and organic carbon components gradually decreased with the increase of soil depth. (3) After reclamation

the δ13C mean difference was small at different soil depths

and the standard deviation and coefficient of variation were larger

indicating that the layers were not obvious in the reclaimed soil and the soil sources might be confused in the same layer. In conclusion

the reclamation work could promote the role of "carbon sinks"

but it could cause damage to soil layer. It was suggested that the reclamation method that disturb the soil layer as little as possible should be adopted

and the topsoil stripping and backfilling process should be optimized so as to achieve better recovery effect.
