| 摘 要： | 应用物理分组方法研究了黄河三角洲典型碱蓬湿地土壤有机碳及其组分分布特征.结果表明,研究区土壤重组有机碳是土壤有机碳的主要组成部分,土壤重组有机碳含量、土壤颗粒有机碳含量与土壤总有机碳含量都显著正相关.研究区土壤轻组组分比例和含量范围分别在0.008%～0.15%和0.10～0.40 g·kg-1,颗粒有机碳分配比例范围为8.83%～30.58%,说明黄河三角洲碱蓬湿地土壤有机碳中非保护性组分较低,碳库相对稳定.

| Abstract: | Applying the method of physical fractionation, distribution characteristics of soil organic carbon and its composition in Suaeda salsa wetland in the Yellow River delta were studied. The results showed that the heavy fraction organic carbon was the dominant component of soil organic carbon in the studied region. There was a significantly positive relationship between the content of heavy fraction organic carbon, particulate organic carbon and total soil organic carbon. The ranges of soil light fraction organic carbon ratio and content were 0.008%-0.15% and 0.10-0.40 g·kg-1, respectively, and the range of particulate organic carbon ratio was 8.83%-30.58%, indicating that the non-protection component of soil organic carbon was low and the carbon pool was relatively stable in Suaeda salsa wetland of the Yellow River delta. |
