典型岩溶县域土壤有机碳的空间分异及主控因素

Shuitu Baochi Xuebao
目的探究岩溶与非岩溶区土壤有机碳(SOC)的空间分异及其主控因素差异。方法以滇东南典型岩溶县域云南省文山市为例，采用网格采样法，调查研究文山市表层(0~20 cm)和深层(0~200 cm)土壤SOC质量分数和空间差异，并运用半变异函数和地理探测器分析外部环境要素对文山市SOC空间分异的影响。结果文山市表层和深层土壤SOC质量分数平均值分别为17.80、5.18 g/kg，总储量为3 770.89×104 t，其中，表层土SOC呈西部高、中北部低的分布格局，深层土SOC呈中西部高、东北部低的分布格局 ...

黄河三角洲新生湿地不同植物群落下土壤钙、镁分布特征

, 2013
以黄河三角洲新生湿地为研究对象,对不同植物群落下湿地土壤Ca、Mg含量的分布特征进行了对比研究。结果表明,不同类型湿地土壤中Ca、Mg含量沿群落演替方向呈波动变化,其水平变异性较大,所有土层均为中等变异(C.V>10%),但Ca的变异性明显大于Mg。Ca的垂直变异性较大,大部分采样点的变异系数在10%以上,属中等变异。影响土壤Ca含量分布的主要因素有成土母质风化迁移以及垂直淋失。比较而言,不同类型湿地土壤中Mg的垂直分布差异不大,其主要受制于湿地土壤水盐条件和成土母质。相关分析表明,土壤中的Ca ...
