摘要：

利用中国第二次土壤普查确定的886个典型地带性土种剖面资料,通过统计分析研究了全国及6个地理区域(华东、华南、西南、东北、华北和西北)地带性土壤表层有机质含量与pH的关系。结果表明,土壤表层有机质含量和pH在不同地理区域间有明显差异;土壤有机质含量有随pH升高而降低的趋势,二者间呈极显著的负相关关系(r=-0.332～-0.530,p<0.001),在控制温度、降雨和海拔条件下,二者间的偏相关关系也均达到1%的显著水平(r偏=-0.217～-0.322);指数方程(SOM=aebpH,a和b为常数)可以较好地描述土壤表层有机质含量与pH的关系,土壤pH变异可以分别解释有机质含量总变异的12.2%～22.9%。
