摘要

以济宁市粉煤灰充填复垦中的园地、耕地和林地为研究对象，研究不同利用方式对复垦土壤的有机碳组分空间分布的影响。通过现场分层采集土样和室内化验指标，研究有机碳组分（WDOC、POC、MOC、LFOC、HFOC、MBC）在不同利用方式土壤中的空间分布特征。结果表明：（1）3种利用方式的全碳（TC）、土壤有机碳（SOC）和土壤有机碳密度（SOCD）均偏低于对照耕地。不同利用方式之间TC、SOC和SOCD的大小关系均为复垦园地＞复垦林地＞复垦耕地。（2）不同利用方式之间有机碳组分差异明显（P＜0.05），SOC与各组分之间均表现为极显著正相关，且关系密切。通过对组分进行相关性分析、比重分析和敏感性分析发现，MOC和HFOC的含量偏低是导致复垦土壤有机碳低于对照耕地的根本原因。（3）根据有机碳组分丰富度指数发现，复垦园地的组分在0—40 cm土层恢复较好，复垦林地在40—60 cm土层恢复较好，复垦耕地恢复效果一般。在0—60 cm土层的综合指数上表现为复垦园地＞复垦林地＞复垦耕地。通过对3种利用方式的有机碳组分空间分布特征进行分析后发现，在济宁市平阳寺镇的粉煤灰充填复垦地中，利用成园地效果最好，值得进一步推广。

Abstract

Taking the reclaimed soil backfilled with coal ash in the Ji’ning region as the research objects

the spatial distribution characteristics of organic carbon components (WDOC

POC

MOC

LFOC

HFOC

MBC) in the reclaimed soil under three different utilization modes: garden land

cultivated land and forest land. The results showed that: (1) The total carbon (TC)

soil organic carbon (SOC) and soil organic carbon density (SOCD) of the three different utilization modes were lower than the control. The sizes of TC

SOC and SOCD in different utilization modes: garden land＞forest land＞cultivated land. (2) The difference of organic carbon components between different utilization modes was significant (P＜0.05)

there were significant positive correlations between the organic carbon and other components. By correlation analysis

specific gravity analysis and sensitivity analysis

the lower contents of MOC and HFOC resulted in the lower soil organic carbon in reclaimed soil than the control. (3) According to the organic carbon component enrichment index

the composition of the garden was recovered well in the 0—40 cm soil layer

the forest land recovered well in 40—60 cm

bute not so much for the recovery in cultivated land. For the composite index of 0—60 cm soil layer

it turned out that garden land＞forest land＞cultivated land. In a word

through analyzing the organic carbon composition

the best utilization mode is garden land

which is worth further promotion.
