The results showed that the grain crop productivity was significantly differed in different districts in Gansu province,the main production region of grain crop productivity changed from west part to east part of Gansu province,as well as changed from irrigation area to rain-fed area. The planting area of wheat decreased sharply from 1991 to 2012,the maize and potato increased year by year. Consequently,the structure of grain crop and planting area changed significantly in the past 21 years,and the benefit of grain crop productivity is the main reason which drives this changing.Read More
