杉木马尾松几个模型的预报有效性的计算机模拟试验

A Computerized Simulation Test on the Effectiveness of Several Models of Chinese Fir and Masson Pine

用计算机模拟试验的方法,对杉木和马尾松平均树高、平均胸径及最大密度的数学模型的预报有效性进行检验。结果表明:各模型的模拟检验精度均达到99.0％以上,并且P{R>R}>85.0％。可认为各模型的总体相关系数及其预报效果是理想的。

This paper deals with the effectiveness of H-HA models, D-H models and maximum density-D models of Chinese fir and Masson pine, making use of computerized simulation tests. The results showed that the simulation test precisions of the models reached up 99.0%, and P {R>R*}> 85.0%. The population correlation coefficients and the forecasting effectiveness of the models were satisfactory.
