Abstract

Based on the cross-entropy theory, a spatial production allocation model (SPAM) has been developed for presenting spatio-temporal dynamics of maize cropping system in Northeast China during 1980–2010, at the pixel level. The AA. further explored spatio-temporal variations of maize with latitude, longitude, and elevation. Discussion of the results. It is highlighted that maize planting density increased gradually to a moderately high level over the investigated period, which reflected the trend of aggregation of maize cultivation driven by market demand
