摘要:

利用内蒙古四子王旗榆树根径(D0.05)和胸径(D1.3)调查数据,研究了榆树根径与胸径的回归关系。结果表明:根径—胸径的二次函数数学模型最优,其最佳适用范围为10~30cm的根径。该研究可为内蒙古毁林案件的查处以及森林抚育和林木采伐利用的监督管理提供参考。

关键词: 榆树, 根径, 胸径, 回归关系

Abstract:

Based on the investigation data of root diameter (D0.05) and DBH (D1.3) of Ulmus pumila in Siziwang Banner,Inner Mongolia,the regression relationship between root diameter and DBH of Ulmus pumila was studied.The results showed that the quadratic function mathematical model of root diameter-DBH was the best,and its optimal application scope was the root diameter of 10~30cm.This study can provide references for the investigation and treatment of deforestation cases in Inner Mongolia,and the supervision and management of forest tending and forest harvesting.

Key words: Ulmus pumila, root diameter, diameter at breast height, regression relationship
