中文摘要	以黄土丘陵区甘肃省定西市龙滩流域白杨纯林及其植被结构调整后形成的白杨(Populus tomentosa) +5年生油松(Pinus tabuliformis)、白杨+10年生油松混交林为对象,分析白杨纯林结构调整后的土壤全碳、土壤有机碳和土壤无机碳的变化,旨在为该区域退化白杨林地的改造模式提供科学依据。结果显示:(1)土壤全碳与有机碳含量变化相似,随着植被恢复年限的增加均呈上升趋势;白杨油松混交林土壤有机碳储量高于白杨纯林,不同样地间土壤全碳与无机碳储量差异不显著(P<0.05)。(2)土壤碳与土壤含水量、容重、pH等土壤理化性质之间存在显著相关关系,土壤水分的增加、pH和土壤容重的降低与土壤碳的累积之间在一定程度上存在协同效应。本研究能够为半干旱黄土丘陵区人工植被的有效恢复和生态系统服务功能的提升提供科学指导。
英文摘要	Understanding the responses of soil carbon to forest structure adjustment is an important issue concerning vegetation restoration in semi-arid regions. In this study, total carbon, organic carbon, and inorganic carbon in soils of three different plantations (Populus tomentosa plantation, Populus tomentosa plantation transformed with Pinus tabuliformis for 5 years, and Populus tomentosa plantation transformed with Pinus tabuliformis for 10 years) were analyzed in a typical semi-arid loess watershed. The results showed that: (1) The temporal changes of soil total carbon and soil organic carbon concentration were similar. Concentrations of soil total carbon and soil organic carbon increased over time. Soil organic carbon storage in both mixed plantations was significantly higher than that in pure plantation. There was no difference in soil total carbon and inorganic carbon storage among the three plantations. (2) Soil carbon concentrations were significantly correlated with soil moisture, bulk density, and pH in different plantations. Increased soil moisture and decreased pH and bulk density had a synergistic effect with increasing soil carbon. Our results can provide scientific guidance to vegetation restoration and the enhancement of ecosystem services in the semi-arid Loess Plateau.
