土壤有机碳对区域碳平衡起着关键性的作用,量化其空间格局及动态变化是准确评估生态系统碳汇潜力的基础。然而,不同土壤有机碳估算方法和不同样本得出的结果存在非常大的差异和不确定性,尤其是地形复杂、对气候变化敏感的青藏高原地区...土壤有机碳对区域碳平衡起着关键性的作用,量化其空间格局及动态变化是准确评估生态系统碳汇潜力的基础。然而,不同土壤有机碳估算方法和不同样本得出的结果存在非常大的差异和不确定性,尤其是地形复杂、对气候变化敏感的青藏高原地区。为定量评估不同方法估算的土壤有机碳密度空间分布格局在青藏高原地区的差异,论文以青海省为研究区,收集整理了青海省806个土壤有机碳密度采样点数据,基于气候、植被、地形和土壤等多种解释变量,采用逐步回归、反距离权重插值、普通克里格插值和随机森林模型4种不同的方法,对青海省表层(0~30 cm)土壤有机碳密度空间分布及其影响因素进行了探究。结果表明,归一化植被指数、光合有效辐射、总氮、年均温、海拔、年降水量和净初级生产力是土壤有机碳密度估算的重要变量;尽管4种方法所估算的青海省土壤有机碳密度的均值较为接近,处于5.14~5.62 kg C·m^(-2)之间,但其变化范围存在较大差异,分别为0.17~23.25、0.34~46.61、0.56~35.08和0.62~24.85 kg C·m^(-2);4种方法模拟结果的均方根误差分别为3.93、3.37、3.48和3.19 kg C·m^(-2),平均标准差分别为0.12、0.51、0.61和0.27 kg C·m^(-2),其中随机森林模型的结果较为稳定且精度较高,也更能准确反映青海省土壤有机碳的空间分布格局。比较发现,现有的土壤有机碳产品(SoilGrids250m 2.0和HWSD v1.2)在反映青海省土壤有机碳的分布方面还存在较大差异,相对而言,SoilGrids250m 2.0产品的土壤有机碳和随机森林模拟结果比较接近。展开更多
