Abstract: |
This paper is reviewed the current research contents about the potential productivity of Chinese arable land.We attempted to sort out the direction and key research content in future..It was found that the urgent requirement was to understand the inner defending mechanisms between the cereal security and the 0.12 billion hectares of basic arable land and their distribution in different regions of China.It was necessary to consider the influence of the climatic changes with land use transfer in regions and farmers on the changes of the potential productivity of Chinese arable land. |
Key words: arable land potential productivity research progress enlightenment |
