Is DBH the same as DBH?

DBH is the trunk diameter of tree height 1.3m, and the ground diameter is the thickness diameter of the tree at 5- 15cm near the ground.

The diameter of most trees is larger than the DBH. Some fast-growing trees will be similar. Some branches are very different when they are low. Therefore, there is a difference between the two.

Extended data:

Ground diameter is a term indicating the measurement position in the measurement of garden seedlings. Ground diameter refers to the diameter of trees (seedlings) at a certain distance from the ground, similar to tree diameter and breast diameter, and is usually used to indicate the specifications of trees and seedlings.

* * * The same understanding refers to "the diameter of the seedling trunk near the ground", but in practical application it is 20 cm above the ground.

Variation difference of ground diameter

According to different varieties, the starting position of some seedlings is 10cm or 30cm above the ground, and the starting position of a few varieties is 5cm. There is no uniform standard in China at present. Different varieties have different starting distances, and different regions have different starting distances. Unless otherwise specified, the starting position of ground diameter is generally 10cm by default.

DBH: Also called trunk diameter, it refers to the DBH of the tree trunk from the ground surface. When the cross section is abnormal, measure the average of the maximum value and the minimum value. Different trees have different DBH, and different countries have different regulations on DBH. In China and most countries, the breast height is set at1.3m above the ground.
