酸雨污染已成为威胁土壤和植物健康的全球性环境问题。为探究酸雨对我国亚热带森林土壤有机碳矿化的影响，选取南京紫金山区域酸碱性不同的森林土壤，通过室内培养试验，以仅添加纯水（CK）和纯水+凋落叶（T0）为对照，模拟凋落叶添加后，pH分别为1.65 （T1）、3.67 （T2）、5.55 （T3）的酸雨对土壤有机碳矿化的影响。结果表明，碱性土壤条件下，各处理CO2累积排放量为1.67~3.35 g·kg-1，表现为T3>T2>T1>T0>CK；而在酸性土壤中，CO2累积排放量为0.99~3.90 g·kg-1，表现为T3>T0>T2>CK>T1。与CK相比，添加凋落叶（T0）后，酸性、碱性土壤CO2累积排放量分别增加了41.20%和71.72%。轻度酸雨（T3）能促进CO2排放，加快凋落叶的分解；...
