摘要
由于树木生长模型是构建林分生长模型的基础,因此国内外许多林业研究者给予了极大关注并发表了许多著名的生长模型。从研究结果上看,各种模型都有一定的适应性;而在生物学意义上,VonBertalanffy模型的解释更令人满意。分析结果证明,该模型拟合性好,无论直径、树高,还是材积,相关指数的平方(R2)均在0.99以上,其平均平方残差(MSSD)直径为0.1520,树高为0.0652,材积为0.000007,而且具有明显的生物学意义。
Because the tree growth model is the basis of construction of forest growth, many national and international researchers put a geat interest in the subject and amounted a lot of famous growth models. The results of the study showed that each model has its proper adaptability. However, in the sense of biology, the explaination of Von Bextalanffy model is satisfied. The result showed the model not only has good fitting, the correlation index square(R2) of the diameter, height and volume are all over 0.99, and its MSSD of the diameter is 01520, the height is 00652, the volume is 0000007, also has significant sense of biology.
