大兴安岭松岭大扬气林场落叶松生长规律研究

树木生长量的大小及生长速率,一方面受树木本身遗传因素的影响,另一方面也受所处环境条件的制约。以大扬气林场的兴安落叶松为研究对象,基于其37株标准木的树干解析、生长数据,利用线性模型、对数模型、多项式模型、指数模型研究不同测树因子(胸径、树高等)之间的关系,分析模拟其生长规律。结果表明:在研究区域内,多项式模型模拟所得到的相关系数相对较高,因此可以利用此模型来预估此区域落叶松的生长规律。

Growth Regularity of Larix gmelinii in Dayangqi Forest Farm of Daxing'anling Region

The growth and growth rate of trees are not only influenced by the genetic factors,but also by the trees and the environmental conditions.Taking Larix gmelinii in Dayangqi Forest Farm as research objects,based on the tree stem analysis and growth data of 37 standard woods,the relationship among different tree sizes (DBH,tree height) were studied by using linear model,logarithm model,polynomial model and exponential model;the growth laws were simulated.Result shows that the model can be used to predict the growth of Larix gmelinii in this area,tre correlation coefficient obtained by polynomial model simulation is relatively high.
