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
