| Abstract: | On the basis of previous research results on potential agricultural productivity, the potential grain productivity of China is studied in this paper with the support of geographic information system (GIS) and national agricultural data\|base including spatial databases and attribute databases. At frist, the concept and development of potential grain productivity are expounded, and the method of GIS based study on the potential grain productivity is discussed. Then, after stressed research on such factors of potential grain productivity as soil effective coefficient, potential land productivity, social effective coefficient, and potential social productivity, the authors put forward some new computing models. Furthermore, using the mechanism methodology and computing models mentioned above, they calculated computed China's national potential grain productivity by county unit. Finally, the predominance of exploiting potential grain productivity regions of China is determined through comparing the computing results with current grain productivity. |
