| 摘 要： | 对人工林与天然次生林的土壤呼吸差异及翻土后对人工林土壤呼吸的影响进行研究，结果表明，天然次生林的土壤呼吸显著小于人工林，而有机质含量却相反；人工林翻土后对土壤呼吸的影响十分显著。因此，保护天然次生林、控制森林砍伐、合理使用土地，这对保持土壤肥力、控制土壤CO2排放、维持全球碳平衡及稳定全球气候变化至关重要。

| Abstract: | Difference of soil respiration between artificial forest and natural secondary forest and effect of turning soil on soil respiration were studied. The results showed that, the soil respiration of natural secondary forest was significanty lower than that of artificial forest , but its content of soil organic matter was higher than that of artifical forest, and that effect of turning soil on soil respiration of artificial forest was significant. Thus, protection for natural secondary forest, restriction of forest cutting and rational utilization of land were important for keeping balance of global carbon and stablizing global climate. |
