Researches about the Effects of Climate Change on China's Grassland Ecosystem

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,degradation of grassland and the trend of basification,grassland carrying capacity is greatly reduced.It severely 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.
