气候变化(主要指气候变暖)使草原区干旱出现的几率加大，持续时间延长；草地土壤侵蚀危害加重，土地肥力降低；草地在干旱气候、荒漠化、盐碱化的作用下，初级生产力下降，草地景观可能呈现荒漠化趋势。草原生态失去平衡，草原植被覆盖率下降，草原出现了明显的沙化、退化和碱化的趋势，草原载畜能力大大降低，严重制约着社会经济发展、农牧民生产和生活。从气候变化对中国草地生态系统生产力和中国草地生态系统碳库的影响两方面阐述了气候变化对中国草地生态系统的影响，并总结了目前的研究动态和研究进展。

Climate change (mainly refers to the climate warming)makes the chances of getting increased probability of drought and the duration.Grassland soil erosion damage is aggravating and it reduces land fertility.Under the action of drought,desertification,salinization,the primary biomass of the grassland community decreased,grassland landscape maybe presents a tendency of desertification.Grassland ecology balance is broken and grassland vegetation coverage is decreasing.There is an obvious desertification,deg-radation of grassland and the trend of basification,grassland carrying capacity is greatly reduced.It severe-ly restricts the social and economic development,the farmers and herdsmen production and life.From the influence of climate change to China's grassland ecosystem productivity and Chinese grassland ecosystem carbon library,This article elaborates the effects of climate change on China's grassland ecosystem,and sums up the current research progress and the research of dynamic.
