| 摘 要： | 全球变暖是当今世界最热的环境问题之一, 其主要原因是大气中CO2浓度剧增。而森林土壤呼吸占生态系统呼吸总量的60%~90%, 是全球碳循环的一个关键组成部分。文中综述主要森林经营措施对土壤呼吸造成影响的程度及方向, 详尽总结采伐、林地施肥、土壤改良、凋落物移除和火烧等措施对土壤呼吸影响的国内外相关研究。

| Abstract: | Global warming is one of the hottest environment problems.One of the reasons is the sharp increase of CO2 in atmosphere. Soil respiration in forest ecosystems accounts to 60%-90% of total ecosystem respiration and is therefore one of the key components of the global C cycle. This paper summarized different responses of soil respiration to forest management measures, and described the relevant researches at home and abroad on the effect of management measures like harvesting, forest fertilization, soil improving (Liming), litter removal, and prescribed burning on soil respiration. |

| Keywords: | forest soil respiration effect factor forest management global warming |
