Description

Tree diameter measuring device

Technical Field

The utility model relates to a tree diameter measurement device.

Background

With the continuous shift of economic development mode to industrialization in China, greenhouse gases such as carbon dioxide in the atmosphere are continuously increased. The forest is used as a main body of a land ecosystem, more than 86% of carbon of a global vegetation carbon bank and 73% of carbon of a global soil carbon bank are gathered, the diameter of the tree is measured, the annual growth amount and the annual carbon fixation amount of the tree are calculated according to the measured tree species growth amount, and the relationship between the carbon fixation capacity and the current tree stock is analyzed. In the current forest resource clearing and forestry investigation research, the diameter of the tree is an index of necessary investigation. The existing tree diameter measurement is that a caliper is clamped on a tree, accurate data can be obtained only by measuring different parts of the tree at the same height for multiple times, and the caliper cannot guarantee the height consistency of multiple measurements.

Disclosure of Invention
