| 摘 要： | 草地碳循环在全球气候变化中起着重要作用,草地碳通量研究是草地碳循环研究的关键问题。由于草地特殊的地理位置及环境特征,使得草地碳通量有别于其他类型的生态系统。草地温室气体特别是CO2和CH4的释放水平具有明显的时空变化特征,其通量变化与许多外部因素相关,包括土壤微生物、土壤温度、土壤湿度、土地利用方式等。本文对近年来草地生态系统碳汇功能变化以及影响碳通量相关因子的研究成果进行了系统的分析和综述。还讨论了草地碳通量研究存在的问题,并对其发展方向进行了展望。

| Abstract: | Grassland plays an important role on global climate changes.The research on grassland carbon flux is a key of grassland carbon cycle.The greenhouse gas emission,especially CO2 and CH4 emission,shows obviously spatial-temporal variation.The carbon flux is related to many exterior factors,including soil animalcule,soil temperature,soil humidity,land use pattern and so on.This paper analyzed and gave an overview of the changes about grassland carbon sink function and the related factors of influencing grassland carbon flux.Based on these researches,this paper discussed the bottleneck of grassland carbon flux progress,especially gave prospects of the developing direction of carbon flux. |
