模拟增温对草地植物、土壤和生态系统碳交换的影响

摘要

Based on the methods of simulated warming,the effects of simulated warming on grassland plants,soil,and ecosystem carbon exchange were summarized.Warming could alter the plant phonologi-cal periods,plant community structure,soil physical and chemical properties as well as ecosystem carbon exchange.However,the results were not consistent because of the time of warming,warming facilities and different environment conditions.Finally,the weakness of current research of effect of simulated war-ming on grassland ecosystem were put forward and the important aspects in the future research were sug-gested.It may provide a better understanding of the effects of warming on grassland ecosystem in the fu-ture.%在分析模拟增温研究方法的基础之上，总结了模拟增温对草地生态系统植物、土壤和生态系统碳交换的影响。增温会提前或者推后草地植物的物候期，影响植物群落结构、土壤理化性质以及生态系统碳交换，但是增温时间的长短、增温装置以及环境条件的不同会导致不同结果。最后，提出了目前研究的不足以及未来模拟气候变暖研究中应关注的重要方向，为全面了解气候变暖对草地生态系统的影响提供参考。
