Northern and northeastern China is the largest base of crop production in China. It is very important to keep and increase the land productivity in this area for food supply and sustainable development of China in the 21st century. In order to evaluate the potential productivities and possible increase of crop production, we, at first, developed a set of digital maps including the base maps, socioeconomic maps, meteorological maps, soil maps, and land use/cover maps at a scale of 1:1,000,000 (or a ground resolution of about 1km). As a result, a set of maps have been produced, which include crop potential productivities under different limiting factors, and the possible increase of production for each crop by improving those limiting factors
