广东省水稻联合收割机保有量预测

Forecast of Paddy Rice Combine in Guangdong Province

采用三次指数平滑预测法、修正指数曲线预测法、部分信息的灰色GM(1,1)预测法对广东省水稻联合收割机保有量的需求建立了预测模型,并通过精度比较及与2006年的实际数据比较,选用适合广东省水稻联合收割机保有量发展规律的三次指数平滑预测和部分信息的灰色预测模型的组合预测模型,对广东省"十一五"期末和"十二五"期末的保有量进行了预测。

The Cubic Exponential Smoothing Method, Modified Exponential Curve Method, Grey Model GM （1,1） are constructed to forecast the paddy rice combine in Guangdong province, Compared with the precision and the actual data in 2006, the combined forecasting model based on the Cubic Exponential Smoothing Method and Grey Model is adopted and forecasts the paddy rice combine of Guangdong province at the end of ＂Eleventh five-year＂ and ＂Twelfth five-year＂.
