Abstract: We studied the materials by principal component regression analysis, the data are season rainfall, month density of Meriones unguicalatus of April to May, October to November in the period of 1981~1986 in Erdosi desert-grasslants. Two mathematical model of the prediction at density under two different conditions were obtained respectively.
