The China-Mongolia-Russia Economic Corridor (CMREC) region is part of the Silk Road Economic Belt and is critical to world food grain safety, and thus, developing its potential grain production will help counter any global food crisis. In this study, a grain production potential measurement system for the CMREC was designed and developed using spatial data to progressively correct environmental factor functions. The potential yield per unit area and potential area of four grain crops in 48 provinces were scientifically and systematically evaluated, and the grain production potential, development potential, and development potential range were calculated. The results show that the grain production potential and development potential of the corridor are significant. The yield of wheat and maize is mainly distributed in Siberia and the south of the Russian Far East. The development potential of soybean is very large and is mainly concentrated in the Russian Far East and northeast region of Mongolia. However, there is little room for paddy yield improvement, and its potential is mainly concentrated in northeast China. The grain production potential forms a high-value region with a low value from north to south, high value in the middle, extending from northwest to southeast. Grain and cereals in the whole region amounted to 8.45 x 10(8) t (4.25 x 10(8) t in Russia, 4.03 x 10(8) t in China, and 0.12 x 10(8) t in Mongolia). In terms of grain type, maize has the highest productivity potential with 1.96 x 10(8) t, followed by wheat at 1.45 x 10(8) t. The potential for paddy is 0.58 x 10(4) t, whereas soybean has the lowest potential of 0.40 x 10(8) t. The results of this study provide evidential support in the form of data for the development of the complementary advantages of agricultural resources, construction of the CMREC, and joint development of a food resource free trade zone. The CMREC will strengthen the development of modern, green, high-yield, high-quality, and efficient grain production zones for soybean and maize, and promote the diversification of grain resource cooperation. |
