摘要

在全球天然林面积持续下降而人工林面积不断增加的背景下

人工林是否能达到天然林的土壤固碳能力尚不清楚。以黄土高原子午岭林区的成熟人工和天然油松林为研究对象

比较分析了不同密度人工林和天然林0—20 cm土层的土壤团聚体组成、不同粒径团聚体土壤有机碳(SOC)、不同活性SOC及球囊霉素相关土壤蛋白(GRSP)的分布特征和相关性。结果表明:(1)人工林表层土壤全土的总SOC含量及其高活性、低活性、非活性SOC组分的含量均显著低于天然林

其中总SOC含量和非活性SOC含量随林分密度增加而增加

低活性SOC含量反之。(2)人工林表层土壤各粒径团聚体的总SOC含量及其组分含量均显著低于天然林。人工林大团聚体的重量百分含量、总SOC含量及非活性SOC含量随林分密度的增加而增加

但均显著低于天然林。(3)人工林表层土壤的SOC含量随林分密度增加而增加

其峰值17.95 g/kg

为天然林SOC含量的65.5%

其中大团聚体的数量及其SOC含量和稳定性的显著降低是导致两者差异的主要原因。活性SOC百分含量与总SOC含量的增加呈负相关关系

GRSP随林分密度增加而增加

但低于天然林

且通过提高大团聚体数量增加总SOC含量。增加人工林林分密度可以增加其表层土壤的生物量、土壤大团聚体数量、GRSP含量

以及降低活性SOC百分含量

进而提高其土壤固碳能力

同时显著降低其植物多样性。

Abstract

It is unclear whether the soil carbon sequestration capacity of plantation forests can reach the level of natural forests

especially under the declining area of natural forests and increasing the area of plantation forests on a global scale.Taking planted and natural Pinus tabuliformis forests in the Ziwuling Forest Region of Loess Plateau as the research object

the distribution characteristics and correlations of soil aggregate composition

soil organic carbon (SOC)

different degrees of labile SOC and Glomalin-related soil protein (GRSP) in 0—20 cm soil layer of different density plantations and natural forests were compared and analyzed.The results showed that:(1) The total SOC content and the content of its composition:very-labile

less-labile

and non-labile SOC in the whole soil of the plantations were significantly lower than those in the natural forests.The total SOC and non-labile SOC contents increased with increasing stand density

while the less-labile SOC content was the opposite.(2) The total SOC and its component contents of each particle size aggregates in the plantations were significantly lower than those in the natural forests.With increasing stand density

the weight percentage of macroaggregates

total SOC content and non-labile SOC content of macroaggregates of plantation forests increased

but were significantly lower than those of natural forests.(3) The SOC content of the plantations increased with the increase of stand density

and its peak value was 17.95 g/kg

which was 65.5% of the SOC content of the natural forests.Among them

the number of macroaggregates and their SOC content was significantly reduced

which was the main reason for the difference.The percentage of labile SOC was negatively correlated with the increase of total SOC content

GRSP increased with the increase of stand density but was lower than that of natural forest

and the total SOC content was increased by increasing the number of macroaggregates.Increasing the plantation stand density can improve its soil carbon sequestration capacity by increasing surface soil biomass

the number of soil macroaggregates

and the GRSP content

and reducing the percentage of labile SOC

but significantly reduces the plant diversity of the plantations.
