【摘要】 通过对 5种 S增长模型的比较及组合选择 ,结果表明 :S增长模型都具有单调性、渐近性和拐点 ,此特征能客观地反映诸多自然和经济规律 .通过一定的加权组合 ,用多个增长模型来反映 S变化过程 ,可以提高拟合的精度 ,多个模型的组合要优于单个模型 .用加权模型可以很好地反映茶秆竹的高生长过程 ,在实际生产中可选择 yp2 或 yp 3 组合更多还原

【Abstract】 Basing on the selection and comparison of 5 kinds of "S"growth model,the results show that all models have the characters of monotony,adience and inflexion,and these can reflect some disciplinarian of nature and economy The combination of several models may improve the precision of equation and is better than the single equation The combination models are superior to reflecting the height growth for Pseudosasa amabilis McCl,and the equations of y p2 and y p3 are practicable更多还原
