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。 Based on the quantity of requisitioned and occupied forest land in China during the “Tenth Five-Year Plan” period, the gray system prediction model is used to predict the trend of expropriation and occupation of forest land during the “Eleventh Five-Year Plan” period of China and the model precision is analyzed and tested. The established GM (1, 1) model is qualified as the qualified test (C = 0.50, P = 1.00), and the predicted data of forest land acquisition and occupancy during the “Eleventh Five-Year Plan” "During the quota for woodland quotas.
