摘要
土壤呼吸是全球碳循环中重要的流通途径之一,是陆地生态系统最大的二氧化碳释放源,也是碳循环的研究领域中一个普遍关注的热点问题。土壤呼吸是土壤中生物与周围环境之间一个相互作用的过程,可以被看作为一个生态系统,明白影响该土壤生态系统里面生物和环境要素、相互作用过程以及其对该系统所排放出二氧化碳的影响有着非常重要的意义。通过分析影响土壤呼吸的主要因素,土壤温度、土壤湿度、土壤有机质和氮含量、生物因子以及人类活动与土壤呼吸的相互作用方式,概括了影响土壤呼吸因素之间的关系,并对土壤呼吸研究今后的发展趋势进行了展望。
Soil respiration is not only an important circulation route in global carbon cycle but also the largest CO2 release source in terrestrial ecosystem, so it is a common focus of attention in the field of the carb6n cy- cle study. Soil respiration is a process of interaction between the biological and ambient soil. The soil can be regarded as an ecological system, and understanding the impact of the soil ecosystem inside biological and en- vironmental factors, interaction, and the impact of the carbon dioxide emissions of the system has a very im- portant significance. In order to describe the main factors affecting soil respiration, such as soil temperature, soil moisture, soil organic matter and nitrogen, biological factors, human activities, etc. , the relationship between soil respiration factors was summarized, and the future development of soil respiration was prospected.
