Abstract

Abstract: Based on the area of requisitioned and occupied forest land during China's“10th Five-Year Plan”period,a grey forecasting model of GM(1,1)was used to forecast the trend of requisitioned and occupied woodland during China's“11th Five-Year Plan”period,and the model precision was analyzed.The results showed that GM(1,1)model was effective(C = 0.50 P = 1.00).The predictive value can be used as one of the references for woodland ration during China's“11th Five-Year Plan”period.

Key words: grey system theory, GM(1,1)model, woodland ration
