| 摘 要： | 利用山东省宁阳县3种不同立地条件下的107-杨树速生丰产林临时标准地和解析木调查材料,以 Richards生长函数为基本模型,拟合了不同立地条件下的107-杨树速生丰产林生长模拟预测模型.结果表明,107-杨树速生丰产林的生长规律呈现"S"型曲线,用Richards模型拟合其胸径、树高、材积的生长精度很高,P值均小于0.0001;使用未参加建模的107-杨解析木数据对构建的预测方程进行T检验,发现预测值与实测值之间无显著差异(P均大于0.05).可见,利用所建生长模型可以对107-杨树速生丰产林的生长动态进行预测,为107-杨树人工林的合理经营提供依据.

| Abstract: | According to Richards function,several models were imitated for estimating 107-poplar based on 107-poplar temporary and fixed standard stands in Ningyang Shandong.The growth of the 107-poplar plantations presented an s-shaped curve,and high accuracy was exhibited by the growth prediction model when it was used to imitate the growth of breast diameter,height and volume of the trees,P<0.0001;Using some data of 107-poplar plantation that are not used for building models to test,the result showed that the measu... |
