| 摘 要： | 本文以Richards模型为基础,推导出了Richards衍生模型,刻服了时间因子获取比较困难的不足,又保留了Richards模型的优点.同时对北京市昌平区西部采用LIDAR技术获得的35株铅笔柏数据应用Richards衍生模型和其它常用的胸径一元材积公式进行了拟合,都通过了F检证,得到了Richards衍生模型的残差平方和最小为0.0315,可用;还可进一步推导出材积树高的Richards衍生模型.

| Abstract: | By Richards model-based,derived from the Richards-derived model,engraved served time factor more difficult to obtain enough to retain the advantages of the Richards model. At the same time,Changping District,Beijing,west of the use of LIDAR technology 35 pencil hodginsii Richards derived data applications and other commonly used model for a dollar volume diameter to fit the formula has been derived from the model of Richards and the smallest residual sum of squares for 0.0315,F through the inspection certif... |
