Abstract: The values of both forest and grassland should be recognized in response to the global climate change,and grassland plants can improve and complement the carbon fixation capacity of forest.Grassland is not only an ecological-type but also an economical-and social-type carbon pool and plays an important role in the global climate change.First,grassland is the largest area of green resources,so its carbon fixation capacity would never be ignored.The costs of grassland carbon fixation are cheaper and the carbon formations are more stable.Not just to assimilate the carbon dioxide,grassland also functions effectively as a carbon sink.Grassland covers the earth as the temperature adjustor and the development of grassland agriculture is favorable to decrease carbon discharge in agricultural industry.Therefore,we should strengthen the protection and construction of grasslands and improve the replying capability to the global change,build up the theory of Great Carbon Pool and pay attention to both grassland and forest,increase the investment and political forces to enhance carbon pool capacity gradually,intensify the legal management of grassland and maintain its stability,make use of the favorable international environment to develop grassland carbon pool,emphasize the research on grassland carbon fixation and improve the scientific supporting capacity,and change Arbor Day to Greening Day to promote grass planting from all citizens.

Key words: Grassland, Global climate change
