摘 要:为编制沙地油松一元立木材积表,对辽西北章古台地区沙地442株油松的地径与胸径数据进行了分析,结果表明:章古台沙地油松的地径与胸径之间存在明显的相关性,采用6种数学模型进行相关分析,其中二次曲线方程D=-3.384+1.0041 d+0.0055 d^(2)为最佳模型,地径与胸径拟合效果良好,可在科研和生产中应用。In order to compile one-way tree volum table of Pinus tabulaeformis in sandy land,the ground diameter and DBH data of 442 P.tabulaeformis trees in the sandy land of Zhanggutai area in Northwest Liaoning Province were analyzed.The results showed that there was an obvious correlation between ground diameter and DBH.Six mathematical models were used to analyze the correlation.The quadratic equation D=-3.384+1.0041 d+0.0055d^(2) was the best model,showing a good fitting effect between ground diameter and DBH,which could be applied in scientific research and production.
