DBH: Also called trunk diameter, it refers to the diameter of the trunk at the height from the ground. When the section is deformed, measure the average of the maximum and minimum values. 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.

DBH is short for DBH. One of the most basic factors in stumpage determination. The trunk off the ground is equivalent to the breast height diameter of an average adult.

Due to the different heights of people, in order to make the measurement points consistent, the specific height of chest height is uniformly stipulated within a country, but it is not consistent in different countries. In China and most countries, the breast height is set at1.3m above the ground. This standard height is more convenient for ordinary adults to measure readings with a wheel ruler.

Discrimination of nouns

Trunk diameter measured at1.3m above the ground.

Also known as the diameter of the trunk, that is, the diameter at breast height, is only applicable to the measurement of trees.

Ground diameter

Also known as bottom diameter, it refers to the diameter of soil trace. * * * The same understanding refers to "the diameter of seedling trunk near the surface", but in practical application, it is 20 cm from the ground, and some requirements are 10cm from the ground.

Jing Peng

Refers to the diameter of shrubs and shrubs' vertical projection plane.

Mijing

Refers to the diameter at 1 m on the ground. (Generally, the rice provided by Miao farmers is mostly of this rice diameter. )

Difference between DBH and flower diameter

The DBH requirement of flowers and trees is the data measured at a specific position of flowers and trees.

There is no such requirement for diameter, and diameter can be measured anywhere.

DBH of the thickest tree

The diameter of the thickest tree is 16.5 meters.

history

The concept of DBH (abbreviated as DBH, abbreviated as DBH) was introduced to China from European countries (non-Japan and the United States), but the height of DBH measured by European countries and most Commonwealth countries is 4 feet 3 inches above the ground, 4 feet 3 inches = 4× 0.3048+3× 0.0254 = 1.25.
