Abstract

以未扰动油松林为对照,研究了油松林皆伐后在不同措施下恢复为幼林地、灌木地和撂荒地0~20cm土层团聚体稳定性、团聚体中
球囊霉素相关土壤蛋白(GRSP)和有机碳(SOC)含量变化特征.结果表明:与对照相比,幼林地团聚体稳定性显著降低(P<0.05),而灌木地及撂
荒地团聚体稳定性显著增加.不同恢复措施团聚体中易提取球囊霉素相关土壤蛋白(EE-GRSP)分布的变化趋势与团聚体稳定性一致,灌木
地团聚体中EE-GRSP 含量相比对照显著增加且最大.灌木地和撂荒地大团聚体(>250μm)中总量球囊霉素相关土壤蛋白(T-GRSP)含量相
比对照显著增加而撂荒地粉黏粒团聚体(<53μm)中T-GRSP含量显著减小.粉黏粒团聚体中EE-GRSP含量普遍大于其他粒径团聚体;微团
聚体(53~250μm)中T-GRSP 含量普遍大于其他粒径团聚体.相比于其他粒径团聚体,大团聚体中T-GRSP 可以更准确的反映土壤碳库的变
化,团聚体稳定性更依赖于大团聚GRSP.

Other Abstract

The objectives of this study were to evaluate the soil aggregate stability, distribution of glomalin-related soil
protein (GRSP) and soil organic carbon (SOC) in different size aggregates from three restoration communities (young
plantation land, shrub land and abandoned forestland) after clear-cutting Pinus tabulaeformis plantation, undisturbed
Pinus tabulaeformis plantation were control treatment. The results showed that soil aggregates were dominated by macro
aggregate (>250μm). Aggregate stability were significantly different among those restoration communities (P<0.05). The
soil aggregate stability in young plantation land was significantly lower than that in the control treatment, while the
aggregate stability in shrub land and abandoned forestland were significantly higher than those in the control treatment.
Content of easily extractable GRSP (EE-GRSP) had similar changes with aggregate stability among all restoration
communities; Content of total GRSP (T-GRSP) in shrub land significant higher than that in the control treatment. On the
other hand, the content of EE-GRSP in clay-silt aggregate (<53μm) was highest than other size aggregates, while the
content of T-GRSP in micro aggregate (53~250μm) was the highest than other size. The aggregate stability significantly
varied among restoration communities, and the changes of EE-GRSP content was consistent with aggregate stabilities
among restoration communites. Our results indicated content of T-GRSP in macro aggregate was a better index to reflect
SOC pool than those in other size aggregates. Moreover, the aggregate stability was mainly depending on the GRSP in
macro aggregate.
