摘　　要：草原生态系统是世界上分布最广泛的植被类型之一,具有重要的生态服务功能,对全球碳水循环发挥着重要作用。刈割作为内蒙古草地常见的利用方式,其会对草原生态系统结构与功能均产生深刻的影响。但目前关于刈割对草原生态系统碳水循环过程影响机制尚不清晰。缺乏长期、连续的通量观测数据是重要原因之一。按照ChinaFLUX标准数据处理方法,我们收集整理了2006–2015年内蒙古锡林浩特温性典型草原生态系统碳水通量和常规气象数据。本数据集提供的长期涡度通量观测数据,不仅为研究刈割利用下草原生态系统碳水通量的时间动态过程及调控机理提供了坚实的数据基础,同时也对优化该区域草地利用管理及评估刈割对我国北方草原碳汇功能的影响具有重要价值。Grassland is one of the most widely distributed vegetation types around the world,and play an important role in the global carbon and water cycle.As a common type of land use in Inner Mongolia,mowing has profoundly affected plant growth and ecosystem functioning of grasslands.However,the influences of mowing on the carbon and water cycle processes in grassland ecosystems are still unclear.A lack of long-term and continuous observation flux data is one of the important reasons.According to the flux data processing procedure by ChinaFLUX,we collected the carbon and water fluxes and conventional meteorological data of typical grassland ecosystems in Xilinhot,Inner Mongolia from 2006 to 2015.This dataset provides a high-quality and continuous long-term eddy flux observation valuable for the research of temporal variations and mechanisms of carbon and water fluxes.Meanwhile,it is important for optimizing grassland management practices and evaluating the role of grassland in regional and global carbon and water cycles.
