黄土高原近40年梯田建设的土壤固碳效益初步估算

open access: yesShuitu Baochi Xuebao
[目的] 为揭示黄土高原梯田土壤有机碳含量的时空规律和梯田土壤固碳时空分布特征。[方法] 基于META分析的方法,研究梯田土壤有机碳含量随土层深度和梯田修建年限的变化特征,分析黄土高原各区域梯田土壤固碳的时空分布特征。[结果] (1)SOC含量和固碳效益随土壤深度的增加而减少,80—100 cm土层的SOC含量为0-20 cm土层的60.74%,0—20 cm土层的固碳效益为23.1%,80—100 cm土层为5.7%。(2)梯田固碳效益随修建年限呈非线性增加,梯田0—20 ...
