Abstract: Agro-grassland is a new agricultural system that gives consideration to ecological and production systems, food and forage. It allows integration with the global economy and adaptation to development. Agro-grassland helps to meet the development of the urban and rural areas, to resolve the traditional agricultural development problems in China, and it will be a milestone on optimizing the agricultural structure. The agro-grassland system was developed in order to implement the party’s “decision” in the Third Plenary Session of the 18th Central Committee of the China Central Committee, which proposed “to strengthen the construction of new think-tank with Chinese characteristics, to establish and improve the system of decision-making consultation”. This paper outlines a concept for building the proposed think-tank information system based on new cloud computing technology, so as to consolidate the existing research results, combine research resources, promote timely information collection and analysis, to make this the “nervous system” of the Agro-grassland concept. A strength will be the sharing of information. The Agro-grassland think tank should be independent, scientific, timely and effective, and be an intelligence platform to provide services for the front-line production enterprises, research institutes and government agencies. It will provide the technology support for the development of Agro-grassland system practice, facilitating structural transformation of Chinese agriculture from the traditional grain-based agriculture to the Agro-grassland system with consideration of both food and forage production in China.
