土壤呼吸是陆地生态系统碳循环的重要环节,在维持全球碳平衡中发挥着十分重要的作用。全球气候变暖会改变大气环流和全球水文循环,进而导致全球的降水格局发生变化,其最直接的影响就是改变土壤的水分状况,关于土壤水分状况对土壤呼吸的影响机理的研究对于预测未来土壤碳储量变化具有重要意义。本文总结了国内外关于土壤水分对土壤呼吸的影响方面的研究,系统分析了土壤水分是怎样影响土壤呼吸的各组成部分的,并简单介绍了土壤水分对Q10值的影响,最后针对当前相关研究存在的问题,对今后的研究方向加以展望。
Soil respiration is an important link in the carbon cycle of terrestrial ecosystems and plays a very important role in maintaining the global carbon balance. Global warming will change the atmospheric circulation and the global hydrological cycle, which led to changes in the global precipitation pattern, the most direct impact is to change the soil moisture status of the soil moisture on the soil respiration impact mechanism for the prediction of future soil Changes in carbon stocks are of great importance. This paper summarizes the research on the influence of soil moisture on soil respiration at home and abroad, systematically analyzes how soil moisture affects the components of soil respiration, and briefly introduces the influence of soil moisture on Q10. Finally, according to the current related research The problems that exist, and future research directions to be looked forward.
