Analysis of Soil Organic Carbon Storage and Influencing Factors in the Soil of Binhai Wetland in Tianjin

  • 摘要:

    对天津滨海湿地的土壤有机碳(SOC)储量进行了研究. 结果表明:滨海湿地土壤表层(0~30 cm)w(SOC)为(8.55±3.98)g/kg,平均土壤有机碳密度为(4.70±1.91)kg/m2,低于全国平均水平. 从土地覆盖类型看,除林地外,滨海湿地土壤中w(SOC)也处于偏低水平. 滨海湿地的土壤中w(SOC)与土壤环境因子有显著相关关系,由此建立回归方程,认为土壤中w(黏粒)和pH是影响土壤中w(SOC)的最主要因素,二者可以解释71.8%的土壤有机碳分布情况. 提出对滨海湿地的改良建议,认为适当地进行人为管理和调控,对土壤环境的改善及土壤有机碳储量的增加有积极作用.
