Abstract

Abstract: Grassland ecosystem is one of the most important terrestrial ecosystems, and its carbon cycle processes play an important role in the global carbon balance. In order to explore the response of ecosystem carbon fluxes to different grazing intensities, this study was conducted in Leymus secalinus grassland of northern Shanxi. We dynamically monitored net ecosystem carbon exchange, ecosystem respiration and gross primary productivity under ungrazing, light grazing, moderate grazing and heavy grazing. The results showed that different grazing intensities had no significant effect on ecosystem carbon fluxes in 2017. In 2018, moderate and heavy grazing increased ecosystem respiration and gross primary productivity to some extent by changing soil temperature and net primary productivity, but still had no significant effect on net ecosystem carbon exchange. Therefore, the results of this study indicate that the response of ecosystem carbon fluxes to different grazing intensities is related to grazing years.

Key words: Ecosystem respiration, Grazing intensities, Leymus secalinus grassland, Gross primary productivity, Net ecosystem carbon exchange

摘要： 草地生态系统是最主要的陆地生态系统之一，其碳循环过程在全球碳平衡中具有重要作用。为探讨草地生态系统碳通量对不同放牧强度的响应，本研究以晋北赖草草地为研究对象，动态监测不放牧、轻度放牧、中度放牧和重度放牧下生态系统净碳交换、生态系统呼吸和生态系统总初级生产力。结果显示，2017年不同放牧强度对生态系统碳通量影响不显著；2018年中度和重度放牧通过改变土壤温度和净初级生产力，一定程度上提高生态系统呼吸和生态系统总初级生产力，但对生态系统净碳交换影响不显著。因此，晋北赖草草地生态系统碳通量对不同放牧强度的响应与放牧年限相关。
