摘要
土壤呼吸的研究早在20世纪之前就已经开始了,国外的研究比国内起步早,目前,有许多研究发现土壤呼吸具有很大的时空变化,为了更加准确了解与探讨土壤呼吸时空变化的规律,本文通过对国内外相关文献的查阅、整理、归纳、总结了其变化特征。时间变化主要有日变化、季变化和年际变化。空间变异主要包括群落水平、景观水平、区域尺度和生物区系尺度四个方面,海拔梯度也会影响土壤呼吸。
The research on soil respiration has already started as early as the 20th century,and the research in foreign countries started earlier than that in China.At present,many studies have found that soil respiration has great temporal and spatial changes.In order to understand and explore the temporal and spatial changes of soil respiration more accurately,the related articles at home and abroad were reviewed,sorted out,summed up and summarized.Temporal changes mainly included diurnal changes,seasonal changes and inter-annual changes.Spatial variability mainly included four aspects:community level,landscape level,regional scale and biotic scale.Altitude gradient also affected soil respiration.
