湿地松胸径与地径关系的研究

Study on the Relationship between the DBH and Basal Diameter of Pinus elliottii

本文利用138株湿地松的地径、胸径资料建立了湿地松胸径与地径的关系模型,结果表明:湿地松胸径与地径的关系可采用直线方程进行模拟;在此基础上,可以通过测定湿地松地径换算成胸径,从而达到估算林木材积的目的,为林政资源管理及林业执法机关的执法提供理论依据,具有十分重要的生产实践意义。

In this paper the DBH and basal diameter data of 138 Pinus elliottii trees were used to establish the relational model between the DBH and basal diameter of Pinus elliottii in Jixi County. The results showed that the relationship between the DBH and basal diameter could be modeled with the linear equation and based on this,the DBH could be converted with the basal diameter measured to achieve the aim of estimating the timber volume and provide theoretical basis for the forestry administration, forest resource management and law enforcement by forestry law enforcement agencies, being of great significance in production practice.
