| 摘 要： | 以蒙古栎（Quercus mongolica）林、杂木林和胡桃楸（Juglans mandshurica）林3种天然次生林土壤为研究对象，通过生长季节内表层土壤（0～30 cm ）淀粉酶、蔗糖酶、脱氢酶和过氧化氢酶活性以及土壤微生物呼吸速率的测定，探讨了辽东山区土壤酶活性与土壤微生物呼吸之间的关系。结果表明：辽东山区蒙古栎林、杂木林、胡桃楸林土壤酶活性与土壤微生物呼吸具有一定的季节波动，但相关性不显著。除胡桃楸林微生物呼吸与过氧化氢酶活性之间具有显著关系外，蒙古栎林和杂木林微生物呼吸与4种酶活性之间均无显著相关性。研究结果为进一步系统了解辽东山区次生林植物群落土壤碳循环过程提供了参考。

| Abstract: | Taking soil in three kinds of natural secondary forest （Quercus mongolica ,weed trees ＆ Juglans mand-shurica） as researching objects ,through determination of amylase ,invertase ,dehydrogenase ＆catalase activity ,the relationship between soil enzyme activities and soil microbial respiration in the mountainous regions of eastern Liaon-ing Province were discussed .Result shows that ：soil enzyme activity ＆ soil microbial respiration of Quercus mon-golica ,weed trees ＆ Juglans mandshurica have certain seasonal fluctuations ,but the correlation is not significant . Except biological respiration ＆ catalase activity of Juglans m andshurica has significant relationship ,microbial res-piration ＆ four kinds of activity of Quercus mongolica ＆ weed trees has no significant correlation .The result pro-vides a reference for understanding systematically the soil carbon cycle of plant communities for secondary forest in the mountainous regions of Eastern Liaoning Province . |
