项目标书摘要：植被恢复可以增加土壤有机碳含量，提高土壤肥力，对煤矿废弃地的环境改善至关重要。阐明不同植被修复模式对土壤有机碳各组分的影响，对揭示土壤固碳机理具有重要意义。本研究以太原市西山煤矿修复林地(栎树、火炬树、松树)为研究对象，分析了土壤碳组分的变化特征。结果表明：植被修复能显著增加煤矿废弃地土壤有机碳含量。三种修复模式下，土壤有机碳、溶解性有机碳和微生物量碳含量差异显著。植被修复模式对土壤无机碳的含量影响不显著；而对土壤有机碳储量影响显著。此外，植被修复可以显著改善土壤理化性质。本研究有助于揭示复垦土壤固碳机制及其与修复方式的关系，旨在为煤矿废弃地生态修复实践提供参考。

Application Abstract: Vegetation restoration tends to increase soil organic C and soil fertility,which is essential for improving the environment in post-mining area.Understanding the effects of vegetation restoration on soil organic C fractions is of great significance for soil C sequestration.Focus on the restoration vegetation in a post-mining area,soil organic C fractions has been investigated by plot survey and lab measurement.The results showed that soil organic C content increased significantly due to vegetation restoration.Soil organic C,soluble organic C,and microbial biomass C varied greatly among vegetation types.The restoration model had no great influence on soil inorganic C,while it affected soil C stock.Moreover,soil characteristics were improved by vegetation restoration.This study is helpful to reveal the relationship between vegetation type and soil C sequestration,and to lay a foundation for ecological restoration and soil C cycle in coal mine areas.
