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.
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, Chang-ping 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 certificate, can be used; can be further deduced volume tree height derived from the Richards model.
