| 摘 要： | 以香樟落叶为分解底物材料，通过模拟酸雨研究酸解对凋落物分解的影响.结果表明，酸解作用在前期对凋落物失重率影响不大，在后期随着酸解增强失重率逐渐增大，凋落物CO2释放在各处理之间差异无统计学意义，但是相应的分解酶如Cx、β-葡萄糖苷酶、α-淀粉酶、漆酶、过氧化物酶等在酸解pH值4.0强度下表现出明显高的活性，说明酸雨酸解作用短期内对香樟凋落物分解有明显的促进作用.

| Abstract: | A 120-day experiment of decomposition was carried out in field using simulated acidolysis of Cinnamomum camphora litter to analyze mass loss，CO2 release and related microbial enzymes.The results showed that acidolysis did not significantly affect mass loss of litter in the former stage，but mass loss increased with strengthening of acidolysis in the later stage.CO2 release in degrading litter had not significant difference among each treatment of acidolysis，but related enzymes such as Cx，β-glucosidase，α-amylase，laccase and peroxidase were significantly improved in the treatment of pH was 4.0.In conclusion，acidolysis of acid rain significantly improves the litter decomposition of C. camphora in the short period. |
