低碳经济与草业发展的新机遇

New Opportunity of Development of the Low-carbon Economy and Prataculture

发展低碳经济是我国应对气候变化的必然选择,草业在低碳经济发展中将发挥重要作用。草地是陆地生态系统大的碳库,在减少和固持CO2方面将发挥主要作用。我国草地资源丰富,并且能源草开发潜力巨大。通过选择碳固持能力高的饲草,优化人工草地种植结构,建植高效固碳人工草地,改善反刍家畜日粮结构,增加优质饲草比例,降低反刍家畜温室气体排放等措施,增加碳的固持能力,推动低碳经济的发展。

Developing the low-carbon economy is the inevitable choice to response the atmosphere change;the prataculture will play an important role in the low-carbon economy.Grasslands are the biggest carbon bank,and play a chief part in reducing and fixing CO2.The grassland resource in China is very rich,and developing potential of energy forage is great.By the measures of selecting the grasses which have high capacity to fix the carbon,optimizing the planting structure of the artificial grasses,establishing the artificial grassland which is highly efficient to fix carbon,improving daily ration structure of the ruminant,increasing the ratio of the premium forage,reducing the greenhouse gases,to increase the capacity of fixing the carbon,the development of the low-carbon economy can be promoted.
