摘要: 以我国“十五”期间征占用林地数量为基础,运用灰色系统预测模型对我国“十一五”期间征占用林地趋势进行预测,并对模型精度进行了分析和检验。建立的GM(1,1)模型经精度检验(C=0.50,P=1.00)判为合格,预测的“十一五”期间林地征占用数据,可作为编制我国“十一五”期间林地定额的参考依据。

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
