摘要

[目的] 为阐明抚育间伐条件下凋落物分解和土壤有机碳(SOC)组分的变化特征

揭示抚育间伐条件下凋落物分解对防护林SOC稳定性的影响。[方法] 在抚育间伐3年后

以3种林分(麻栎林、黑松林和麻栎-黑松林)的海岸带防护林凋落物和表层(0—20 cm)土壤为研究对象

采用凋落物原位分解、室内化学性质分析和随机森林模型等分析方法

表征3种抚育间伐强度(对照0

轻度15%

重度30%)下凋落物分解特征和SOC组分

并分析其关系。[结果] 重度抚育间伐显著增加麻栎和麻栎-黑松凋落物在分解过程中的质量剩余

较对照分别增加22.36%和4.18%

代表凋落物分解速率的K值变化特征趋势则与之相反;麻栎林和麻栎—黑松林的SOC、矿物结合有机碳(MAOC)和SOC稳定性均随抚育间伐强度升高显著增加;在抚育间伐条件下

SOC及其稳定性与凋落物分解过程中的氮、磷残留率极显著相关

与凋落物分解速率不相关。[结论] 抚育间伐降低凋落物的分解速率

但增加凋落物碳、氮和磷的残留率

尤其在重度间伐条件下。抚育间伐提高SOC的稳定性

SOC及其稳定性的变化主要受凋落物氮和磷的残留率影响

其中磷残留率的影响最大。

Abstract

[Objective] To elucidate the characteristics of litter decomposition and changes in soil organic carbon (SOC) fractions under thinning

and to reveal the impact of litter decomposition on the stability of SOC in coastal shelter forests under thinning. [Methods] After three years of thinning

the litter and surface soil (0—20 cm) of coastal shelter forests (Quercus acutissima Carruth. (QAC)

Pinus thunbergii Parl. (PTP) and mixed Q. acutissima Carruth. andP. thunbergii Parl. (QP) in Qingdao were studied. In situ decomposition of litter

indoor analyses of chemical properties

and random forest model were used to characterize the litter decomposition and SOC fractions under three different thinning intensities (control 0

light 15% and heavy 30%)

and analyzed their relationships. [Results] Heavy thinning significantly increased the mass remaining of QAC and QP litter during decomposition

with an increase of 22.36% and 4.18% compared to the control

respectively. The trend of K-value changes representing litter decomposition rate was opposite to mass remaining. The SOC content

mineral associated organic carbon (MAOC) content

and SOC stability of QAC and QP all significantly increased with the increase of thinning intensity. The content and stability of SOC were significantly correlated with nitrogen and phosphorus residual rates during litter decomposition under thinning

but not with litter decomposition rate. [Conclusion] Thinning reduces the decomposition rate of litter

but increases the residual rates of carbon

nitrogen

and phosphorus in litter

especially under heavy thinning. Thinning improves the stability of SOC

and the changes in SOC content and stability are mainly influenced by the residual rates of nitrogen and phosphorus in litter

with phosphorus residual rate having the greatest impact.
