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。
Global warming is one of the hottest environmental problems in the world today, mainly due to the dramatic increase in atmospheric CO2 concentration. Forest soil respiration, which accounts for 60% to 90% of the total ecosystem respiration, is a key component of the global carbon cycle. In this paper, the extent and direction of the impact of main forest management measures on soil respiration are summarized. The domestic and international researches on the effects of cutting, forest fertilization, soil improvement, litter removal and fire on the soil respiration are summarized.
