Abstract: In this paper, the population and grain output of the Loess Plateau region are predicted with the unequal interval time-series models. The accuracy of the models are 95.68% and 99.43% respectively. This provides a decision-making basis for working out a comprenensive exploitation plan in the region.

Key words: population, grain output, prediction model
