陆地生态系统土壤呼吸的影响因素研究综述

Research review of the impact factors on soil respiration in terrestrial ecosystem

土壤呼吸是陆地生态系统碳循环中的一个重要过程,也是陆地生态系统最大的二氧化碳释放源,对全球气候和环境变化产生重要影响。对国内外关于陆地生态系统土壤呼吸影响因素的研究进行综述,分析了温度、水分、土壤性质等非生物因素,植被、土壤微生物、土壤动物等生物因素以及人类活动等对土壤呼吸产生的影响。最后分析了目前有关土壤呼吸研究中存在的问题,并提出了今后努力的方向:改进和创新土壤呼吸的测量方法,拓宽土壤呼吸的研究范围,加强土壤呼吸组分的区分研究,重视人类活动对土壤呼吸影响的研究。

Soil respiration is not only an important process of carbon cycling in terrestrial ecosystem,but also is the largest CO_2 releases source in terrestrial ecosystems,which have an important impact on the global climate and environment change.Based on the research on soil respiration of the previous scholars at home and abroad,both biological and non-biological factors that influence the soil respiration were reviewed,including temperature factors,moisture, soil properties, vegetation, soil microbes,soil animals and induction of human activities,etc. Previous studies have indicated that temperature and moisture are the most important effects in soil respiration influence factors. The future research works on soil respiration were put forward： Soil respiration measurement methods should be improved and innovated,and the research scope of soil respiration should be broaden,and the components of soil respiration research should be strengthened. With the increasing of human impacts,the research of human activities on soil respiration is becoming more important.
